The ocean covers 70 percent of Earth 's surface. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth. The ocean makes all life on Earth possible, and makes the planet appear blue when viewed from space. Earth is the only planet in our solar system that is definitely known to contain liquid water. Although the ocean is one continuous body of water, oceanographers have divided it into five principal areas: the Pacific, Atlantic, Indian, Arctic, and Southern Oceans. The Atlantic, Indian, and Pacific Oceans merge into icy waters around Antarctica. Climate The ocean plays a vital role in climate and weather . The sun’s heat causes water to evaporate , adding moisture to the air. The oceans provide most of this evaporated water. The water vapor condenses to form clouds, which release their moisture as rain or other kinds of precipitation . All life on Earth depends on this process, called the water cycle . The atmosphere receives much of its heat from the ocean. As the sun warms the water, the ocean transfers heat to the atmosphere. In turn, the atmosphere distributes the heat around the globe. Because water absorbs and loses heat more slowly than land masses, the ocean helps balance global temperatures by absorbing heat in the summer and releasing it in the winter. Without the ocean to help regulate global temperatures, Earth’s climate would be bitterly cold. Ocean Formation After Earth began to form about 4.6 billion years ago, it gradually separated into layers of lighter and heavier rock. The lighter rock rose and formed Earth’s crust . The heavier rock sank and formed Earth’s core and mantle . The ocean’s water came from rocks inside the newly forming Earth. As the molten rocks cooled, they released water vapor and other gases. Eventually, the water vapor condensed and covered the crust with a primitive ocean. Today, hot gases from the Earth’s interior continue to produce new water at the bottom of the ocean. Ocean Floor Scientists began mapping the ocean floor in the 1920s. They used instruments called echo sounders , which measure water depths using sound waves . Echo sounders use sonar technology. Sonar is an acronym for SOund Navigation And Ranging. The sonar showed that the ocean floor has dramatic physical features, including huge mountains, deep canyons , steep cliffs , and wide plains . The ocean’s crust is a thin layer of volcanic rock called basalt . The ocean floor is divided into several different areas. The first is the continental shelf , the nearly flat, underwater extension of a continent. Continental shelves vary in width. They are usually wide along low-lying land, and narrow along mountainous coasts. A shelf is covered in sediment from the nearby continent. Some of the sediment is deposited by rivers and trapped by features such as natural dams. Most sediment comes from the last glacial period , or Ice Age, when the oceans receded and exposed the continental shelf. This sediment is called relict sediment . At the outer edge of the continental shelf, the land drops off sharply in what is called the continental slope . The slope descends almost to the bottom of the ocean. Then it tapers off into a gentler slope known as the continental rise. The continental rise descends to the deep ocean floor, which is called the abyssal plain . Abyssal plains are broad, flat areas that lie at depths of about 4,000 to 6,000 meters (13,123 to 19,680 feet). Abyssal plains cover 30 percent of the ocean floor and are the flattest feature on Earth. They are covered by fine-grained sediment like clay and silt. Pelagic sediments, the remains of small ocean organisms, also drift down from upper layers of the ocean. Scattered across abyssal plains are abyssal hills and underwater volcanic peaks called seamounts. Rising from the abyssal plains in each major ocean is a huge chain of mostly undersea mountains. Called the mid-ocean ridge , the chain circles Earth, stretching more than 64,000 kilometers (40,000 miles). Much of the mid-ocean ridge is split by a deep central rift, or crack. Mid-ocean ridges mark the boundaries between tectonic plates . Molten rock from Earth’s interior wells up from the rift, building new seafloor in a process called seafloor spreading . A major portion of the ridge runs down the middle of the Atlantic Ocean and is known as the Mid-Atlantic Ridge. It was not directly seen or explored until 1973. Some areas of the ocean floor have deep, narrow depressions called ocean trenches . They are the deepest parts of the ocean. The deepest spot of all is the Challenger Deep , which lies in the Mariana Trench in the Pacific Ocean near the island of Guam. Its true depth is not known, but the most accurate measurements put the Challenger Deep at 11,000 meters (36,198 feet) below the ocean’s surface—that’s more than 2,000 meters (6,000 feet) taller than Mount Everest, Earth’s highest point. The pressure in the Challenger Deep is about eight tons per square inch.

Ocean Life Zones From the shoreline to the deepest seafloor, the ocean teems with life. The hundreds of thousands of marine species range from microscopic algae to the largest creature to have ever lived on Earth, the blue whale. The ocean has five major life zones, each with organisms uniquely adapted to their specific marine ecosystem . The epipelagic zone (1) is the sunlit upper layer of the ocean. It reaches from the surface to about 200 meters (660 feet) deep. The epipelagic zone is also known as the photic or euphotic zone, and can exist in lakes as well as the ocean. The sunlight in the epipelagic zone allows photosynthesis to occur. Photosynthesis is the process by which some organisms convert sunlight and carbon dioxide into energy and oxygen . In the ocean, photosynthesis takes place in plants and algae. Plants such as seagrass are similar to land plants—they have roots, stems, and leaves. Algae is a type of aquatic organism that can photosynthesize sunlight. Large algae such as kelp are called seaweed . Phytoplankton also live in the epipelagic zone. Phytoplankton are microscopic organisms that include plants, algae, and bacteria. They are only visible when billions of them form algal blooms , and appear as green or blue splotches in the ocean. Phytoplankton are a basis of the ocean food web . Through photosynthesis, phytoplankton are responsible for almost half the oxygen released into Earth’s atmosphere. Animals such as krill (a type of shrimp), fish, and microscopic organisms called zooplankton all eat phytoplankton. In turn, these animals are eaten by whales, bigger fish, ocean birds, and human beings. The next zone down, stretching to about 1,000 meters (3,300 feet) deep, is the mesopelagic zone (2). This zone is also known as the twilight zone because the light there is very dim. The lack of sunlight means there are no plants in the mesopelagic zone, but large fish and whales dive there to hunt prey . Fish in this zone are small and luminous . One of the most common is the lanternfish, which has organs along its side that produce light. Sometimes, animals from the mesopelagic zone (such as sperm whales ( Physeter macrocephalus ) and squid) dive into the bathypelagic zone (3), which reaches to about 4,000 meters (13,100 feet) deep. The bathypelagic zone is also known as the midnight zone because no light reaches it. Animals that live in the bathypelagic zone are small, but they often have huge mouths, sharp teeth, and expandable stomachs that let them eat any food that comes along. Most of this food comes from the remains of plants and animals drifting down from upper pelagic zones. Many bathypelagic animals do not have eyes because they are unneeded in the dark. Because the pressure is so great and it is so difficult to find nutrients , fish in the bathypelagic zone move slowly and have strong gills to extract oxygen from the water. The water at the bottom of the ocean, the abyssopelagic zone (4), is very salty and cold (2 degrees Celsius, or 35 degrees Fahrenheit). At depths up to 6,000 meters (19,700 feet), the pressure is very strong—11,000 pounds per square inch. This makes it impossible for most animals to live. Animals in this zone have bizarre adaptations to cope with their ecosystem. Many fish have jaws that look unhinged. The jaws allow them to drag their open mouth along the seafloor to find food, such as mussels, shrimp, and microscopic organisms. Many of the animals in this zone, including squid and fish, are bioluminescent. Bioluminescent organisms produce light through chemical reactions in their bodies. A type of angler fish, for example, has a glowing growth extending in front of its huge, toothy mouth. When smaller fish are attracted to the light, the angler fish simply snaps its jaws to eat its prey. The deepest ocean zone, found in trenches and canyons, is called the hadalpelagic zone (5). Few organisms live here. They include tiny isopods , a type of crustacean related to crabs and shrimp. Invertebrates such as sponges and sea cucumbers thrive in the abyssopelagic and hadalpelagic zones. Like many sea stars and jellyfish, these animals are almost entirely dependent on falling parts of dead or decaying plants and animals, called marine detritus . Not all bottom dwellers, however, depend on marine detritus. In 1977, oceanographers discovered a community of creatures on the ocean floor that feed on bacteria around openings called hydrothermal vents. These vents discharge superheated water enriched with minerals from Earth’s interior. The minerals nourish unique bacteria, which in turn nourish creatures such as crabs, clams, and tube worms. Ocean Currents Currents are streams of water running through a larger body of water. Oceans, rivers, and streams have currents. The ocean’s salinity and temperature and the coast’s geographic features determine an ocean current’s behavior. Earth’s rotation and wind also influence ocean currents. Currents flowing near the surface transport heat from the tropics to the poles and move cooler water back toward the Equator . This keeps the ocean from becoming extremely hot or cold. Deep, cold currents transport oxygen to organisms throughout the ocean. They also carry rich supplies of nutrients that all living things need. The nutrients come from plankton and the remains of other organisms that drift down and decay on the ocean floor. Along some coasts, winds and currents produce a phenomenon called upwelling . As winds push surface water away from shore, deep currents of cold water rise to take its place. This upwelling of deep water brings up nutrients that nourish new growth of plankton, providing food for fish. Ocean food chains constantly recycle food and energy this way.

Some ocean currents are enormous and extremely powerful. One of the most powerful is the Gulf Stream , a warm surface current that originates in the tropical Caribbean Sea and flows northeast along the eastern coast of the United States. The Gulf Stream measures up to 80 kilometers (50 miles) wide and is more than a kilometer (3,281 feet) deep. Like other ocean currents, the Gulf Stream plays a major role in climate. As the current travels north, it transfers moisture from its warm tropical waters to the air above. Westerly, or prevailing, winds carry the warm, moist air to the British Isles and to Scandinavia , causing them to have milder winters than they otherwise would experience at their northern latitudes . Northern parts of Norway are near the Arctic Circle but remain ice-free for most of the year because of the Gulf Stream. The weather pattern known as El Niño includes a change to the Humboldt Current (also called the Peru Current) off the western coast of South America. In El Niño conditions, a current of warm surface water travels east along the Equator and prevents the normal upwelling of the cold, nutrient-rich Humboldt Current. El Niño, which can devastate the fisheries of Peru and Ecuador, occurs every two to seven years, usually in December. The paths of ocean currents are partially determined by Earth’s rotation. This is known as the Coriolis effect . It causes large systems, such as winds and ocean currents that would normally move in a straight line, to veer to the right in the northern hemisphere and to the left in the southern hemisphere . People and the Ocean For thousands of years, people have depended on the ocean as a source of food and as a route for trade and exploration . Today, people continue to travel on the ocean and rely on the resources it contains. Nations continue to negotiate how to determine the extent of their territory beyond the coast. The United Nations’ Law of the Sea treaty established exclusive economic zones (EEZs), extending 200 nautical miles (230 miles) beyond a nation’s coastline. Even though some countries have not signed or ratified the treaty (including the U.S.), it is regarded as standard. Russia has proposed extending its EEZ beyond 200 nautical miles because two mid-ocean ridges, the Lomonosov and Medeleev Ridges, are extensions of the continental shelf belonging to Russia. This territory includes the North Pole. Russian explorers in a submersible vehicle planted a metal Russian flag on the disputed territory in 2007. Through the centuries, people have sailed the ocean on trade routes . Today, ships still carry most of the world’s freight , particularly bulky goods such as machinery, grain, and oil . Ocean ports are areas of commerce and culture. Water and land transportation meet there, and so do people of different professions: businesspeople who import and export goods and services; dockworkers who load and unload cargo ; and ships’ crews. Ports also have a high concentration of migrants and immigrants with a wide variety of ethnicities, nationalities, languages, and religions. Important ports in the U.S. are New York/ New Jersey and New Orleans. The busiest ports around the world include the Port of Shanghai in China and the Port of Rotterdam in the Netherlands. Ocean ports are also important for a nation’s armed forces. Some ports are used exclusively for military purposes, although most share space with commercial businesses. “The sun never sets on the British Empire” is a phrase used to explain the scope of the empire of Great Britain , mostly in the 19th century. Although based on the small European island nation of Great Britain, British military sea power extended its empire from Africa to the Americas, Asia, and Australia. Scientists and other experts hope the ocean will be used more widely as a source of renewable energy . Some countries have already harnessed the energy of ocean waves, temperature, currents, or tides to power turbines and generate electricity. One source of renewable energy are generators that are powered by tidal streams or ocean currents. They convert the movement of currents into energy. Ocean current generators have not been developed on a large scale, but are working in some places in Ireland and Norway. Some conservationists criticize the impact the large constructions have on the marine environment. Another source of renewable energy is ocean thermal energy conversion (OTEC). It uses the difference in temperature between the warm, surface water and cold, deep water to run an engine. OTEC facilities exist in places with significant differences in ocean depth: Japan, India and the U.S. state of Hawai'i, for instance. An emerging source of renewable energy is salinity gradient power , also known as osmotic power. It is an energy source that uses the power of freshwater entering into saltwater. This technology is still being developed, but it has potential in delta areas where fresh river water is constantly interacting with the ocean. Fishing Fishers catch more than 90 million tons of seafood each year, including more than 100 species of fish and shellfish . Millions of people, from professional fishers to business owners like restaurant owners and boat builders, depend on fisheries for their livelihood . Fishing can be classified in two ways. In subsistence fishing, fishers use their catch to help meet the nutritional needs of their families or communities. In commercial fishing , fishers sell their catch for money, goods or services. Popular subsistence and commercial fish are tuna, cod, and shrimp. Ocean fishing is also a popular recreational sport. Sport fishing can be competitive or noncompetitive. In sport fishing tournaments, individuals or teams compete for prizes based on the size of a particular species caught in a specific time period. Both competitive and noncompetitive sport fishers need licenses to fish, and may or may not keep the caught fish. Increasingly, sport fishers practice catch-and-release fishing, where a fish is caught, measured, weighed, and often recorded on film before being released back to the ocean. Popular game fish (fish caught for sport) are tuna and marlin. Whaling is a type of fishing that involves the harvesting of whales and dolphins. It has declined in popularity since the 19th century but is still a way of life for many cultures, such as those in Scandinavia, Japan, Canada, and the Caribbean. The ocean offers a wealth of fishing and whaling resources, but these resources are threatened. People have harvested so much fish and marine life for food and other products that some species have disappeared. During the 1800s and early 1900s, whalers killed thousands of whales for whale oil (wax made from boiled blubber ) and ivory (whales’ teeth). Some species, including the blue whale ( Balaenoptera musculus ) and the right whale, were hunted nearly to extinction . Many species are still endangered today. In the 1960s and 1970s, catches of important food fish, such as herring in the North Sea and anchovies in the Pacific, began to drop off dramatically. Governments took notice of overfishing —harvesting more fish than the ecosystem can replenish . Fishers were forced to go farther out to sea to find fish, putting them at risk. (Deep-sea fishing is one of the most dangerous jobs in the world.) Now, they use advanced equipment, such as electronic fish finders and large gill nets or trawling nets, to catch more fish. This means there are far fewer fish to reproduce and replenish the supply. In 1992, the collapse, or disappearance, of cod in Canada’s Newfoundland Grand Banks put 40,000 fishers out of work. A ban was placed on cod fishing, and to this day, neither the cod nor the fisheries have recovered. To catch the dwindling numbers of fish, most fishers use trawl nets. They drag the nets along the seabed and across acres of ocean. These nets accidentally catch many small, young fish and mammals. Animals caught in fishing nets meant for other species are called bycatch . The fishing industry and fisheries management agencies argue about how to address the problem of bycatch and overfishing. Those involved in the fishing industry do not want to lose their jobs, while conservationists want to maintain healthy levels of fish in the ocean. A number of consumers are choosing to purchase sustainable seafood . Sustainable seafood is harvested from sources (either wild or farmed) that do not deplete the natural ecosystem. Mining and Drilling Many minerals come from the ocean. Sea salt is a mineral that has been used as a flavoring and preservative since ancient times. Sea salt has many additional minerals, such as calcium, that ordinary table salt lacks. Hydrothermal vents often form seafloor massive sulfide (SMS) deposits , which contain precious metals. These SMS deposits sit on the ocean floor, sometimes in the deep ocean and sometimes closer to the surface. New techniques are being developed to mine the seafloor for valuable minerals such as copper, lead, nickel, gold, and silver. Mining companies employ thousands of people and provide goods and services for millions more. Critics of undersea mining maintain that it disrupts the local ecology . Organisms—corals, shrimp, mussels—that live on the seabed have their habitat disturbed, upsetting the food chain. In addition, destruction of habitat threatens the viability of species that have a narrow niche . Maui’s dolphin ( Cephalorhynchus hectori maui ), for instance, is a critically endangered species native to the waters of New Zealand’s North Island. The numbers of Maui’s dolphin are already reduced because of bycatch. Seabed mining threatens its habitat, putting it at further risk of extinction. Oil is one of the most valuable resources taken from the ocean today. Offshore oil rigs pump petroleum from wells drilled into the continental shelf. About one-quarter of all oil and natural gas supplies now comes from offshore oil deposits around the world. Offshore drilling requires complex engineering . An oil platform can be constructed directly onto the ocean floor, or it can “float” above an anchor. Depending on how far out on the continental shelf an oil platform is located, workers may have to be flown in. Underwater, or subsea, facilities are complicated groups of drilling equipment connected to each other and a single oil rig. Subsea production often requires remotely operated underwater vehicles (ROVs). Some countries invest in offshore drilling for profit and to prevent reliance on oil from other regions. The Gulf of Mexico near the U.S. states of Texas and Louisiana is heavily drilled. Several European countries, including the United Kingdom, Denmark, and the Netherlands, drill in the North Sea. Offshore drilling is a complicated and expensive program, however. There are a limited number of companies that have the knowledge and resources to work with local governments to set up offshore oil rigs. Most of these companies are based in Europe and North America, although they do business all over the world. Some governments have banned offshore oil drilling. They cite safety and environmental concerns. There have been several accidents where the platform itself has exploded, at the cost of many lives. Offshore drilling also poses threats to the ocean ecosystem. Spills and leaks from oil rigs and oil tankers that transport the material seriously harm marine mammals and birds. Oil coats feathers, impairing birds’ ability to maintain their body temperature and remain buoyant in the water. The fur of otters and seals are also coated, and oil entering the digestive tract of animals may damage their organs. Offshore oil rigs also release metal cuttings, minute amounts of oil, and drilling fluid into the ocean every day. Drilling fluid is the liquid used with machinery to drill holes deep in the planet. This liquid can contain pollutants such as toxic chemicals and heavy metals . Pollution Most oil pollution does not come from oil spills, however. It comes from the runoff of pollutants into streams and rivers that flow into the ocean. Most runoff comes from individual consumers. Cars, buses, motorcycles, and even lawn mowers spill oil and grease on roads, streets, and highways. (Runoff is what makes busy roads shiny and sometimes slippery.) Storm drains or creeks wash the runoff into local waterways, which eventually flow into the ocean. The largest U.S. oil spill in the ocean took place in Alaska in 1989, by the tanker Exxon Valdez . The Exxon Valdez spilled at least 10 million gallons of oil into Prince William Sound. In comparison, American and Canadian consumers spill about 16 million gallons of oil runoff into the Atlantic and Pacific Oceans every year. For centuries, people have used the ocean as a dumping ground for sewage and other wastes. In the 21st century, the wastes include not only oil, but also chemical runoff from factories and agriculture . These chemicals include nitrates and phosphates , which are often used as fertilizers . These chemicals encourage algae blooms. An algae bloom is an increase in algae and bacteria that threatens plants and other marine life. Algae blooms limit the amount of oxygen in a marine environment, leading to what are known as dead zones , where little life exists beneath the ocean’s surface. Algae blooms can spread across hundreds or even thousands of miles. Another source of pollution is plastics . Most ocean debris, or garbage, is plastic thrown out by consumers. Plastics such as water bottles, bags, six-pack rings, and packing material put marine life at risk. Sea animals are harmed by the plastic either by getting tangled in it or by eating it. An example of marine pollution consisting mainly of plastics is the Great Pacific Garbage Patch . The Great Pacific Garbage Patch is a floating dump in the North Pacific. It’s about twice the size of Texas and probably contains about 100 million tons of debris. Most of this debris comes from the western coast of North America (the U.S. and Canada) and the eastern coast of Asia (Japan, China, Russia, North Korea, and South Korea). Because of ocean currents and weather patterns, the patch is a relatively stable formation and contains new and disintegrating debris. The smaller pieces of plastic debris are eaten by jellyfish or other organisms, and are then consumed by larger predators in the food web. These plastic chemicals may then enter a human’s diet through fish or shellfish. Another source of pollution is carbon dioxide. The ocean absorbs most carbon dioxide from the atmosphere. Carbon dioxide, which is necessary for life, is known as a greenhouse gas and traps radiation in Earth’s atmosphere. Carbon dioxide forms many acids, called carbonic acids , in the ocean. Ocean ecosystems have adapted to the presence of certain levels of carbonic acids, but the increase in carbon dioxide has led to an increase in ocean acids. This ocean acidification erodes the shells of animals such as clams, crabs, and corals. Global Warming Global warming contributes to rising ocean temperatures and sea levels . Warmer oceans radically alter the ecosystem. Global warming causes cold-water habitats to shrink, meaning there is less room for animals such as penguins, seals, or whales. Plankton, the base of the ocean food chain, thrives in cold water. Warming water means there will be less plankton available for marine life to eat. Melting glaciers and ice sheets contribute to sea level rise . Rising sea levels threaten coastal ecosystems and property. River deltas and estuaries are put at risk for flooding. Coasts are more likely to suffer erosion . Seawater more often contaminates sources of fresh water. All these consequences—flooding, erosion, water contamination—put low-lying island nations, such as the Maldives in the Indian Ocean, at high risk for disaster. To find ways to protect the ocean from pollution and the effects of climate change, scientists from all over the world are cooperating in studies of ocean waters and marine life. They are also working together to control pollution and limit global warming. Many countries are working to reach agreements on how to manage and harvest ocean resources. Although the ocean is vast, it is more easily polluted and damaged than people once thought. It requires care and protection as well as expert management. Only then can it continue to provide the many resources that living things—including people—need.

The Most Coast . . . Canada has 202,080 kilometers (125,567 miles) of coastline. Short But Sweet . . . Monaco has four kilometers (2.5 miles) of coastline.

No, the Toilet Doesn't Flush Backward in Australia The Coriolis effect, which can be seen in large-scale phenomena like trade winds and ocean currents, cannot be duplicated in small basins like sinks.

Extraterrestrial Oceans Mars probably had oceans billions of years ago, but ice and dry seabeds are all that remain today. Europa, one of Jupiter's moons, is probably covered by an ocean of water more than 96 kilometers (60 miles) deep, but it is trapped beneath a layer of ice, which the warmer water below frequently cracks. One of Saturn's moons, Enceladus, has cryovolcanism, or ice volcanoes. Instead of erupting with lava, ice volcanoes erupt with water, ammonia, or methane. Ice volcanoes may indicate oceanic activity.

International Oil Spill The largest oil spill in history, the Gulf War oil spill, released at least 40 million gallons of oil into the Persian Gulf. Valves at the Sea Island oil terminal in Kuwait were opened on purpose after Iraq invaded Kuwait in 1991. The oil was intended to stop a landing by U.S. Marines, but the oil drifted south to the shores of Saudi Arabia. A study of the Gulf War oil spill (conducted by the United Nations, several countries in the Middle East and the United States) found that most of the spilled oil evaporated and caused little damage to the environment.

Ocean Seas The floors of the Caspian Sea and the Black Sea are more like the ocean than other seas they do not rest on a continent, but directly on the ocean's basalt crust.

Early Ocean Explorers Polynesian people navigated a region of the Pacific Ocean now known as the Polynesian Triangle by 700 C.E. The corners of the Polynesian Triangle are islands: the American state of Hawai'i, the country of New Zealand, and the Chilean territory of Easter Island (also known as Rapa Nui). The distance between Easter Island and New Zealand, the longest length of the Polynesian Triangle, is one-quarter of Earth's circumference, more than 10,000 kilometers (6,200 miles). Polynesians successfully traveled these distances in canoes. It would be hundreds of years before another culture explored the ocean to this extent.

The Ocean: Life Below Water and Why it Matters

Key questions >>>

• Why does the ocean matter? How is the ocean important for sustainable development?
• What does the sustainable blue economy offer us?
• What are the ocean knowledge gaps?
• How do we need to develop a multidisciplinary ocean science?

The ocean covers around three-quarters of the earth's surface and contains more than 90% of living species on our planet. The ocean is also the single largest ecosystem in the world, and it provides food for billions of people worldwide, as well as maritime transport, renewable energies, and other goods and services like regulating, cultural and supporting services. 

Nevertheless, the ocean is not indestructible, and our footprint is very large. Overfishing, toxic pollution, invasive species, nutrient over-enrichment, habitat degradation and destruction, biodiversity loss, dependence of a growing global population on its goods and services, and coastal development, all threaten the sustainability of coastal ocean ecosystems ( Vanderweerd in Sherman and McGovern, 2011). Ocean acidification is also a growing threat that may be more important than warming, pollution and overfishing (Roberts, 2011).

Why Does the Ocean Matter?

Oceans mean different things for different people: life, passion or wonderment; vastly important; a very important source of life and energy; an incredible source of food and amazing source of biodiversity; it's wild, exciting, terrifying and exhilarating; means a lot to me, if something happens I will not have the fun I’m used to; it's a livelihood, it's been there for generations and hopefully will be there for generations to come.’ (Adapted from video excerpt, Plymouth Marine Laboratory, 2011, in Muñoz-Sevilla and Le Bail 2017).

According to the World Wildlife Fund, the ocean is currently valued at $24 trillion dollars. The goods and services from marine environments add up to an additional $2.5 trillion yearly. This means the ocean would have the seventh-largest GDP in the world.  However, the value of the ocean relies on its current output, which in turn depends on its conditions. Climate change, ocean acidification, habitat destruction, pollution and overfishing are endangering the ocean and threatening its value and the security and livelihood of the three billion people who depend on it. Most of these people live in Small Island Developing States, they are among the ones who contribute least to these issues, but they are the ones at most risk, as they’re already vulnerable. ( Hoegh-Guldberg 2015)

Agenda 2030: SDG 13 and SDG 14

A historical change has been taking place for the past 23 years, from Agenda 21 to Agenda 2030. At the Rio de Janeiro Earth Summit in 1992, more than 178 countries adopted Agenda 21. The Millennium declaration was adopted after the 2000 Millennium Summit in New York. 10 years after the Rio Earth Summit, in the Millennium Development Goals (MDGs) that were adopted during the Earth Summit in Johannesburg, ocean issues were included in the conversation for the first time. 

In 2012, at the United Nations Conference on Sustainable Development (also popularly known as Rio+20), member states adopted the document titled “The Future We Want”, which set the process of developing the sustainable development goals (SDGs) building on the MDGs. Finally, during the UN Sustainable Development Summit in 2015, seventeen SDGs were adopted which are an integral part of the 2030 Agenda.  

Progress of SDG 14 in 2019

The expansion of protected areas for marine biodiversity and existing policies and treaties that encourage responsible use of ocean resources are still insufficient to combat the adverse effects of overfishing, growing ocean acidification and worsening coastal eutrophication. As billions of people depend on oceans for their livelihood and food source, increased efforts and interventions are needed to conserve and sustainably use ocean resources at all levels. 

• Ocean acidification is caused by the uptake of atmospheric CO 2 by the ocean, which changes the chemical composition of the seawater. Long-term observations over the past 30 years have shown an average increase of acidity of 26 percent since pre-industrial times. At this rate, an increase of 100 to 150 percent is predicted by the end of the century, with serious consequences for marine life. 
• To achieve sustainable development of fisheries, fish stocks must be maintained at a biologically sustainable level. Analysis reveals that the fraction of world marine fish stocks that are within biologically sustainable levels declined from 90 percent in 1974 to 66.9 percent in 2015. 
• As of December 2018, over 24 million km 2 (17.2 per cent) of waters under national jurisdiction (0–200 nautical miles from a national border) were covered by protected areas, a significant increase from 12 percent in 2015 and more than double the extent covered in 2010. The protected areas increased from 31.2 per cent in 2000 to 44.7 per cent in 2015 and to 45.7 per cent in 2018. 
• Illegal, unreported and unregulated fishing remains one of the greatest threats to sustainable fisheries, the livelihoods of those who depend upon them and marine ecosystems. Most countries have taken measures to combat such fishing and have adopted an increasing number of fisheries management instruments in the past decade. 
• Small-scale fisheries are present in almost all countries, accounting for more than half of total production on average, in terms of both quantity and value. To promote small-scale fishers’ access to productive resources, services and markets, most countries have developed targeted regulatory and institutional frameworks. However, more than 20 per cent of countries have a low to medium level of implementation of such frameworks, particularly in Oceania and Central and South Asia.

The Ocean Decade

To recognize that more needs to be done to mitigate the global decline in ocean health, in December 2017, the UN declared 2021 to 2030 as the decade of ‘Ocean Science and Sustainable Development’. 

The Ocean Decade will strengthen international cooperation in all levels by strengthening dialogues, developing partnerships, developing capacity-building and leveraging investment, while supporting the entire 2030 Agenda for sustainable development. Other critical goals include improving ocean literacy and education to modify social norms and behaviors, and creating new models for ocean action.

The Ocean Decade aims to include science-informed mitigation and adaptation policies around the world and share knowledge with coastal communities who are most vulnerable to the changes of the ocean. (Claudet et al. 2019)

The COVID-19 Pandemic and the Ocean 

From Little Blue Letter, Glen Wright

• Marine creatures are enjoying some quiet time as underwater noise levels drop. Scientists are studying these effects on marine mammals.
• ​From Florida to Thailand, the number of sea turtles nests has increased on the now-empty beaches. The rapid recovery of marine wildlife in coastal areas shows how extensive our impacts are and highlights the importance of protected areas. 
• Fishers around the world are struggling with decreased demand, lack of sanitary conditions and logistical challenges. In some countries, like India, food security of the communities may be affected by this disruption of supply chains.
• PADI and Rash’R are producing (non-profit)  reusable face masks made from Ocean plastic , with designs based on sea animals!

Final Remarks

We can all take small steps towards protecting our ocean. Reduction of single-use plastic, responsible fish consumption, avoiding ocean harming products, and making your voice heard can all directly contribute towards a healthier ocean. However, more indirect approaches can be taken by reducing the amount of greenhouse gases produced by our daily activities and, therefore, reducing our carbon footprint. Reducing red meat consumption, consuming locally sourced products and using personal vehicles less are all examples of small steps we can take towards reducing our impact. The sum of individual actions can truly make a difference in the fate of our ocean.

Collectively, we need to form a global ocean community, acknowledging that all of our actions have an impact on the ocean (Claudet et al. 2019). And, although it is incumbent on each of us to take steps to protect the ocean, collective action is also required. New models for ocean action, which are collaborative, intergenerational, cross-cultural, and multi-sectoral, are needed in the coming decade, in order to protect our beloved ocean. 

The ocean is our life support system, it connects every one of us, you can think of the ocean as the blue heart  of this planet, but then we look after that heart and we know how we are damaging it and it needs intensive care. We know that scientists, politicians and stakeholders are talking to each other, but it isn’t just up to them, each and every one of us can make the difference, even if the difference might be small, after all individual small drops of sea water can make up the vast ocean . (Adapted from video excerpt, Plymouth Marine Laboratory 2011, in Muñoz-Sevilla and Le Bail 2017).

Water is an extremely important element for the survival of all living organisms on our planet. The significance of water is crucial in more than one way. Furthermore, there’s no substitute for water. Regardless of the huge amount of water on the planet, usable and drinking water is very limited. Even though water covers 71% of the earth’s crust, just around 3% of it is suitable for human use. However, we waste water and pollute it, which has created issues like water scarcity for all. There is a continuous depletion of groundwater as well.

A hungry person can stay without eating food, but a thirsty one cannot go on without water since living without fluids is impossible. This essay on water for class 3 will help kids learn about the importance of water.

Everyone, including humans and plants, requires water. People, creatures, and flora all need water. Life cannot exist without water; everyone and everything will perish if no water is available. Water helps in maintaining our body temperature and aids in digestion too. Aquatic animals use oxygen and nutrients present in water for their survival.

There are two kinds of water available on our planet – fresh water and salt water, and the ocean is all salt water. Humankind uses most water for irrigation, home, and business purposes. The quantity of drinkable or fresh water on earth is diminishing daily; therefore, we must save it. We should store water and then use it wisely. We must not leave the tap running or wash our automobiles with water pipes for long hours.

FEATURE IMAGE SSID: (1931142059) (ALT<(Essay On Importance of Water – 10 Lines, Short and Long Essay for Children>)

Water represents life. Water is a precious resource, a fundamental human requirement, and a valuable asset that all living things possess. Every child should understand the importance of water in daily life.

There are many reasons why water is considered one of the most important and valuable resources on our planet. Let us look at this in a more detailed manner.

Significance Of Water

Water is the cornerstone of human survival when it comes to life. A human body requires water every single day. We might be capable of not eating for seven days; however, we won’t last even three days without drinking water. Furthermore, approximately 60% of human bodies are made up of water which aids our body’s normal functioning. As a result, ingesting impure water will cause major health issues in humans. Therefore, the amount and quality of water we drink are critical to everyone’s physical health and wellness.

Furthermore, our everyday activities would be incomplete without water, like brushing our teeth or preparing meals. Also, many companies use water on a massive scale as almost every single activity of their procedure requires water.

Water has an important function in the lives of all living organisms. From the tiniest insect to the largest whale, each life requires water to stay alive. Water is not just a human need but also flora and fauna. Water is necessary for the planet’s life to function. We should not be self-centred and utilise it for our purposes without caring for the consequences.

Water For Life Processes

• Water plays a crucial part in most biological functions as a solvent. Several waste materials are also eliminated as a solution via urination and sweat.
• Water aids in maintaining body temperature. We take plenty of fluids when it’s hot outside, which keeps the body temperature stable. Water also escapes from the body’s surface as sweat, which removes heat from the body and gets to normal temperature.
• Water is required for plants to make food.

Uses Of Water

• In our daily lives, water is utilised for drinking, dishwashing, baking, showering, and wiping.
• We need water daily for our home gardens too.
• A hydroelectric power plant uses water to create energy.
• Water is being used to irrigate crops and create a variety of items.
• Many water sports include swimming, sailing, kayaking, etc.
• Water can also be used to put out fires.
• Water is necessary for the correct operation of farmed fish, dairies, and many other non-farm operations.
• The majority of fresh water is frozen.
• The oceans contain just about all the water on the planet.
• The salt content of salty water fluctuates.
• One single drop could hold a great deal of life.
• Comets might have also provided some water in the earth’s history. 

Your child will learn how to improve their writing and creative abilities. They will also discover how important water is for their bodies and the ecosystem and the various ways they might use it. They will learn about the importance of water on this planet, not just for humans but for all living things. Last but not least, students will learn about several water-related facts.

1. What Will Happen If Water Vanishes?

Complete vegetation would die rapidly without water, making the earth brown instead of greenish-blue. As clouds will fail to develop and there will be no rainfall, the climate will be dominated entirely by atmospheric circulation. Life as we know it would cease to exist. 

2. Why Should We Not Waste Water?

Water is scarce, despite its abundance, and cannot be regenerated. We must utilise it with caution.

To summarise, water is indeed the foundation of all living things on the planet. Recognising fresh water’s importance and educating people about it is necessary.

100 Words Essay on Life Below Water

Introduction.

Life below water is a world full of wonder and mystery. It is home to a diverse array of creatures, from tiny plankton to giant whales.

Importance of Life Below Water

Marine life plays a vital role in the world’s ecosystem. It provides food, regulates climate, and contributes to the air we breathe.

Threats to Marine Life

However, human activities like pollution, overfishing, and climate change are threatening life below water. These actions disrupt the balance and can lead to the loss of species.

Conservation Efforts

It’s crucial to protect marine life. Conservation efforts include creating marine reserves, reducing pollution, and promoting sustainable fishing.

We must respect and protect life below water. It’s not just about the creatures in the sea, but our survival too.

250 Words Essay on Life Below Water

The importance of life below water.

Life Below Water, a phrase that encapsulates the vast, diverse, and often unexplored world beneath the ocean’s surface, is an essential element of our planet’s ecosystem. It is home to millions of species, many of which are yet to be discovered and plays a critical role in regulating the Earth’s climate.

Marine Biodiversity and Ecosystem

The marine ecosystem is a treasure trove of biodiversity, teeming with a multitude of species that range from the smallest plankton to the largest mammal – the Blue Whale. This rich biodiversity is a crucial contributor to the global food chain, supporting millions of human lives. Moreover, it acts as a buffer against climate change by absorbing large amounts of CO2.

Threats to Oceanic Life

Despite its importance, life below water faces numerous threats. Overfishing, pollution, and climate change are the primary culprits, leading to habitat destruction and species extinction. The bleaching of coral reefs, a critical habitat for many marine species, is a glaring example of the impact of these threats.

The Need for Conservation

Conservation of life below water is not just an environmental issue, but also a socio-economic one. Healthy oceans are vital for sustainable fishing, tourism, and even medicine. Therefore, it’s crucial to advocate for sustainable practices, strict regulations on marine pollution, and the establishment of marine protected areas.

In conclusion, life below water is a vital component of our planet’s health and prosperity. It is our collective responsibility to ensure its conservation for the benefit of future generations.

500 Words Essay on Life Below Water

Life below water is a realm of existence that is as fascinating as it is crucial to the overall balance of our planet. This underwater world, covering about 71% of the Earth’s surface, is home to a diverse array of species and ecosystems, playing a vital role in maintaining the planet’s health and survival.

The Biodiversity of Underwater Life

The underwater ecosystem is a vibrant and diverse world teeming with life. From the microscopic plankton, the foundation of the aquatic food chain, to the colossal blue whales, the ocean’s biodiversity is staggering. Coral reefs, often referred to as the rainforests of the sea, host approximately 25% of all marine species. These ecosystems, despite only covering less than 0.1% of the ocean’s floor, are hotspots of underwater biodiversity, providing shelter, food, and breeding grounds for numerous species.

The Role of Oceans in Climate Regulation

Oceans act as the Earth’s thermostat, regulating the global climate and weather patterns. They absorb about 30% of the carbon dioxide produced by humans, buffering the impacts of global warming. The ocean’s currents distribute heat around the planet, maintaining a balance that allows diverse ecosystems to flourish. Phytoplankton, tiny marine plants, contribute significantly to this process by absorbing carbon dioxide for photosynthesis and releasing oxygen. In fact, they are responsible for producing over half of the world’s oxygen, highlighting the ocean’s role in sustaining life not only underwater but also on land.

Threats to Life Below Water

Despite its importance, life below water faces numerous threats. Overfishing, pollution, and climate change are among the most pressing issues. Overfishing depletes fish populations faster than they can reproduce, disrupting the food chain and leading to a decline in overall marine biodiversity. Pollution, particularly plastic pollution, is another significant threat, with millions of tons of plastic waste ending up in the ocean each year, causing harm to marine life.

Climate change, driven by greenhouse gas emissions, leads to ocean warming and acidification, both of which have devastating impacts on marine life. Coral reefs are particularly vulnerable, with mass bleaching events and die-offs becoming increasingly common as the oceans warm.

The Path Forward

Addressing these threats requires concerted global action. Sustainable fishing practices, stricter pollution controls, and ambitious climate action are all necessary to protect life below water. The global community must recognize the intrinsic value of the ocean’s biodiversity and the essential role it plays in supporting life on Earth.

In conclusion, life below water is a complex, diverse, and vital part of our planet. It plays a crucial role in climate regulation, supports a vast array of species, and provides resources upon which human societies depend. However, it is under threat from human activities. As we move forward, it is essential that we take steps to protect and preserve this remarkable world beneath the waves.

Essay on Water Pollution in 500 Words

The term “water pollution” is employed when human or natural factors lead to contamination of bodies of water, such as rivers, lakes, and oceans. Responsible management is now imperative to address this significant environmental concern. The primary sources of water contamination are human-related activities like urbanization, industrialization, deforestation, improper waste disposal, and the establishment of landfills.

The availability of freshwater on our planet is limited, and pollution only increases this scarcity. Every year, a substantial amount of fresh water is lost due to industrial and various other types of pollution. Pollutants encompass visible waste items of varying sizes as well as intangible, hazardous, and lethal compounds.

Numerous factories are situated in proximity to water bodies, utilizing freshwater to transport their waste. This industrial waste carries inherent toxicity, jeopardizing the well-being of both plant and animal life. Individuals living close to polluted water sources frequently suffer from skin problems, respiratory ailments, and occasionally even life-threatening health conditions.

Water contamination is also intensified by urban waste and sewage, adding to the problem. Each household generates considerable waste annually, including plastic, chemicals, wood, and other materials. Inadequate waste disposal methods result in this refusal to infiltrate aquatic ecosystems like rivers, lakes, and streams, leading to pollution.

Raising awareness about the causes and consequences of water pollution is crucial in significantly reducing its prevalence. Encouraging community or organizational clean-up initiatives on a weekly or monthly basis plays a pivotal role. 

To eradicate water contamination completely, stringent legislation needs to be formulated and diligently enforced. Rigorous oversight would promote accountability, potentially deterring individuals and groups from polluting. Each individual should recognize the impact of their daily actions and take steps to contribute to a better world for generations to come.

My affection for my town has always been heightened by its abundant lakes, rivers, and forests. During one of my walks alongside the river that flowed through my village, I was struck by the unusual hues swirling within the water. The once-familiar crystal-clear blue had been replaced by a murky brown shade, accompanied by a potent, unpleasant odour. Intrigued, I decided to investigate further, descending to the riverbank for a closer look at the source of the peculiar colours and smells. Upon closer inspection, I observed peculiar foam bubbles floating on the water’s surface.

Suddenly, a commotion behind me caught my attention, and I turned to witness a group of people hastening toward the river. Their frantic shouts and vigorous gestures conveyed their panic, prompting me to realize that a grave situation was unfolding. As the group reached the river, they were confronted with the distressing sight of numerous lifeless fish floating on the water’s surface. 

Following a comprehensive investigation, it was revealed that a local factory had been releasing toxic chemicals into the river, resulting in extensive pollution and the devastation of the ecosystem. This investigation left me stunned and disheartened, acknowledging the significant effort required to restore the river to its own form.

• Water Scarcity Essay

Essay on Water Scarcity

Water is the basic necessity of every human being, but water scarcity is a major issue that is rising very rapidly in India nowadays. The problem has become so severe that in many states the groundwater has almost dried up and people have to depend on water supply from other sources. In addition, water is one of the most misused natural resources that we still waste. It is the central point of our lives but unfortunately, not our priority concern. 

Earlier, people understood the value of water and planned their lives around it. Moreover, many civilizations were born and lost around water, but today, in spite of having knowledge, we still fail to understand the value of water in our lives. 

Reasons for Water Scarcity

Mismanagement of water and the growing population in our country are the two main reasons for water scarcity. There are also a number of other man made disturbances that continue to rise. Besides this, some of the reasons for water scarcity are:  

Wasteful Use of Water for Agriculture  

India, an agricultural country, produces a huge quantity of food to feed its population. The surplus that is left, gets exported outside. 

It is not unknown that producing this much food requires a lot of water too. The traditional method of irrigation wastes a lot of water due to evaporation, water conveyance, drainage, percolation, and the overuse of groundwater. Besides, most of the areas in India use traditional irrigation techniques that stress the availability of water.

However, the technique of irrigation has changed during modern times and we provide water to plants using a sprinkler or drip irrigation.

Reduction in Water Recharges Systems  

Rapid construction that uses concrete and marbles may not let the rainwater get absorbed in the soil, but still, we install some mechanism in our houses so that we can hold the rainwater. Then we can recharge the groundwater.

Lack of Water Management and Distribution

There is a need for an efficient system to manage and distribute the water in urban areas. The Indian government also needs to enhance its technology and investment in water treatment. Besides, we should ensure optimization at the planning level.

Solutions to Overcome this Problem

Close the running tap.

 During dishwashing and hand washing people often let the tap run. These running taps waste thousands of liters of water per year. Therefore, closing the tap will reduce this problem.

Replace Dripping Taps  

In India, it is commonly seen that most of the houses have taps or faucets that go on dripping water even when they are closed. This running tap wastes up to 30,000 liters of water that nobody bothers to change. So, we should replace these taps immediately.

Brief on Water Scarcity  

Water is a basic necessity for every living being.  Life without water is impossible, not just for us humans, but for all plants and animals too. Water scarcity is an issue of grave concern these days as water scarcity has become very common. Water is one of the most wasted natural resources and corrective measures should be taken before the water scarcity situation becomes worse. In spite of being aware of the implications, not much is being done today. 

In India, and across the world, it has been recorded that about half a billion people face a shortage of water for about six months annually. Many well-known cities around the world are facing acute scarcity of water. Many facts and figures are available to know about the water scarcity problem, but what are the reasons for this scarcity? 

With the growing population, the use of water has increased manifold. The lack of more freshwater sources and the increase in population is a major reason for this scarcity. The lack of proper Water management systems and proper drainage systems in India, especially in the urban areas is a major cause too. Kitchen wastewater should be able to be recycled but due to a poor drainage system, this is not possible. An efficient water management system is required in order to distribute water in urban areas.

Another major issue is Deforestation. Areas with more greenery and plants are known to have good rainfall.  Industrialisation and urbanization are two major factors here. Due to Deforestation, and cutting down of trees, rainfall has become an issue too.

Rivers are a major source of fresh water in India. Today we see a lot of industries that have come up and all of them are mostly near the rivers and these rivers become highly polluted as a result of all the industrial waste.

Effect of Global Warming and Climate Change

Global Warming and Climate Change are also responsible for the scarcity of water. The melting of icebergs into the sea due to the rise in temperatures is a reason as to how salty water is increasing day by day instead of freshwater. The percentage of rainfall has decreased drastically these days. Climate change along with the decrease in rainfall percentage has greatly affected freshwater bodies. 

Water scarcity has become a major problem and an alarming issue these days, and we must consciously strive to work together to find some solution to this issue of water scarcity. The Indian government today has formulated and come up with many plans on how to tackle and solve this problem.

To conclude, water scarcity has become an alarming issue day by day. If we do not take the problem of water scarcity seriously now, our future generations are going to suffer severely and may even have to buy this necessity at a high cost.

FAQs on Water Scarcity Essay

1.  What are the reasons for Water Scarcity?

The lack of proper Water Management and proper Drainage system plays a major role. Many other factors and reasons can be held responsible for the scarcity of water. Some of the major reasons are Global Warming and Climate Change; Pollution of the rivers due to industrialization; Deforestation and the cutting down of trees is another reason; Reduced percentage of rainfall due to the climate change pattern; Increase in the population which leads to increase in the use of water.  Learn more about water scarcity on Vedantu website helpful for long-term.

2. What is meant by the scarcity of water?

The scarcity of water means a shortage of water and not being able to manage the demand and supply of water. Water scarcity refers to the lack of freshwater bodies to meet the standard quantity and demand of water. Unequal distribution of water due to factors like Climate Change and Global Warming. Water Scarcity is also due to pollution and lack of rainfall. Water scarcity means a scarcity due to some physical scarcity or scarcity due to the lack of regular supply.

3. What are the two types of water scarcity?

Physical water scarcity is the result of regions' demand outpacing the limited water resources found in that location. According to the Food and Agricultural Organization (FAO) of the United Nations, about 1.2 billion people live in areas of physical scarcity and many of these people live in arid or semi-arid regions. People who are affected by this Physical kind of water scarcity are expected to grow as the population increases and as the weather patterns keep changing as a result of climate change.

Economic water scarcity is due to the lack of proper water infrastructure and a proper water management system or also because of poor management of water resources. The FAO estimates that more than 1.6 billion people face economic water shortages today. Economic water scarcity can also take place because of the unregulated use of water for agriculture and industry.

4.  How can we solve the problem?

Conscious awareness is required to deal with and understand the problem of water scarcity. We can start off by consciously saving water in our homes and surroundings.  Small easy steps like taking care when washing hands, or when working in the kitchen, have to be taken. The running water taps are a major reason for losing hundreds of liters of water on a daily basis. And we should be careful not to waste this water. Conscious decision to save and the need to understand the problem of water scarcity is of utmost importance.

5. How do we waste water?

Water is wasted in ways we do not even realize, in our homes and in our workplaces. When we brush our teeth, when we shave or when we wash the dishes, one of the most common things we do is to keep the water running, especially when running water is available. As soon as we begin cleaning or washing, we do not think of the water that is being wasted. While washing hands, we leave the water tap on, which results in wasting water too. Small things like these should be kept in mind and this could be our small step towards preserving water.

Short Essay on River in 100 Words

A river is a naturally flowing stream of water. Rivers usually rise from a mountain or large lake and flow towards an ocean, sea, or another river. Many rivers are seasonal and are fed by rainwater or snow water. Some rivers flow into the ground and dry up before reaching another water body. Rivers bring not just water but also silt, which gets deposited on the banks, making the soil fertile.

Rivers provide cheap transportation, an easy source of food, and fresh water for drinking, cleaning, and farming. Most of the ancient civilizations like those in Egypt, Mesopotamia, China, and India, settled around rivers. Rivers are truly the cradle and the backbone of human civilization. 

Short Essay on River in 200 Words

A river is a naturally flowing stream of water that flows from high altitude to low altitude due to the force of gravity. Rivers usually rise from a mountain or large lake and flow towards an ocean, sea, or another river. They can be perennial rivers that flow throughout the year or seasonal rivers which carry either rainwater or snow water.

Some rivers flow into the ground and dry up before reaching another water body. Small rivers are often called streams, brooks, creeks, or rivulets. Many small rivers often join bigger rivers forming their tributaries. Bigger rivers then flow to even bigger water bodies. 

As rivers flow from highlands to lowlands, they don’t just bring water but also silt. This silt gets deposited on the river banks making the soil extremely fertile. Most of the ancient civilizations like those in Egypt, Mesopotamia, China and India, settled around rivers as rivers made farming possible.

Rivers also provide a cheap mode of transportation, nutritious food in the form of fish, and fresh water for drinking, cleaning, and other activities. In many places, rivers are used to generate electricity, drive machinery as well as dispose of sewage and waste. 

Rivers are truly the cradle and the backbone of human civilization. They have given us life for thousands of years. It is our duty now to keep them clean and save them.

Essay On River

500 words essay on river.

Rivers are the backbone of human civilizations which provide freshwater that is the basic necessity for human life. We cannot live without water and rivers are the largest water bodies for freshwater. In fact, all civilizations in the past and present were born near river banks. In other words, they are veins of the earth that make life possible. Through an essay on rivers, we will take a look at their importance and how to save them.

Importance of Rivers

We refer to rivers as the arteries of any country. No living organism can live without water and rivers are the most important source of water. Almost all the early civilizations sprang up on the river banks.

It is because, from ancient times, people realized the fertility of the river valleys. Thus, they began to settle down there and cultivate the fertile valleys. Moreover, rivers originate from mountains which carry down rock, sand and soil from them.

Then they enter plains and water keeps moving slowly from the mountainsides. As a result, they deposit fertile soil. When the river overflows, this fertile soil deposits on the banks of rivers. Thus, bringing fresh fertile soil constantly to the fields.

Most importantly, rivers help in agriculture. In fact, a lot of farmers depend on rivers for agricultural purposes. Rivers have the ability to turn deserts into productive farms. Further, we can use them for constructing dams as well.

Further, rivers also are important highways. That is to say, they offer the cheapest method of transport. Before road and railways, rivers were essential means of transportation and communication.

In addition, rivers bring minerals down from hills and mountains. We construct damns across the river for generating hydel power and also preserve the wildlife. Further, they also come in use for encouraging tourism and developing fisheries.

Save Rivers

As pollution is on the rise, it has become more important than ever to save rivers. We must take different measures to do so. First of all, we must use biodegradable cleaning products and not use chemical products for body washing.

Further, we must not waste water when we shower. After that, we must install the displacement device in the back of the toilet for consuming less water. It is also essential to turn the tap off while brushing or shaving.
