Torn at the Genes

One Family's Debate Over Genetically Altered Plants

By Jennifer Nelson, Clyde Freeman Herreid

Share Start a Discussion

The setting for this case is the family dinner table, where a heated discussion about genetically altered foods is taking place. Marsha Cumberland’s brother-in-law has joined the family for dinner. Ed is an industry official whose job it is to decide whether or not new products need pre-market approval by the FDA. He has just returned from a conference on transgenic foods.  When it turns out that some of the food on the dinner table is genetically modified, a debate ensues with different members of the family at different ends of the spectrum. Written for an introductory biology course, the case considers the scientific and ethical issues of genetically altered plants.

Little Details

Welcome to my little realm

Torn at the Genes: Ones family’s debate over genetically altered plants

In this case study, there was a family who debated about whether or not genetically altered foods were safe. The mother and eldest daughter were on the not-safe side while the youngest daughter and the uncle were on the safe side. The uncle provided facts and details as to how GMOs help with the environment and can provide a bigger crop yield for the growing population. The mother had added that GMOs could harm the environment and could harm the people eating them. Towards the end of the argument, nobody was swayed for either side, so the debate on GMOs could go either way, it depends on whether you can see the benefit they have.

Why is writing essays so hard?

Patterns and boring topics imposed by schools and universities are not very conducive to creativity and human development. Such essays are very difficult to write, because many are not interested in this and do not see the meaning of the text. There are a number of criteria that make it impossible to write essays:

• Boring and incomprehensible topics. Many topics could be more interesting, but teachers formulate them in a way that makes you want to yawn.
• Templates. 90% do not know how to make an essay interesting, how to turn this detailed answer to a question into a living story.
• Fear of not living up to expectations. It seems to many that the essay is stupid and that they simply did not understand the question. There is a fear of getting a bad mark and disappointing the professor, parents and classmates. There is a fear of looking stupid and embarrassing in front of the team.
• Lack of experience. People don't know what and how to write about. In order to make a good essay, you need to have a perfect understanding of the topic and have the skills of a writer.

That is why the company EssaysWriting provides its services. We remove the responsibility for the result from the clients and do everything to ensure that the scientific work is recognized.
