Genetically Modified Foods

Extracts from this document...

Introduction

David Ballard Biology 4/30/2005 Genetically Modified Foods Throughout time there have been many changes in the types of food we eat. There have been changes in the way food is grown and produced. Many people are unaware of what they are actually eating when they buy vegitables at the grocery store. The new changes in the foods today, are known as GM, genetically modified foods. Many people do not support the growing and consuming of genetically modified foods but I do. The term GM foods or GMO's means genetically modified organisms. They are foods that have been created for humans and animals consumption. These GMO's are produced by the latest molecular biology techniques. When the plants are modified in the laboratories they are being modified in many different ways for many different purposes. In the laboratories the traits of the plants are modified. Examples of traits that are modified are increased resistance to herbicides, and improved nutritional content. ...read more.

With the natural pest resistances this makes it so farmers don't need to use chemical pesticides, which are very harmful to the environment and to humans. People don't want to eat food that has been treated with chemical pesticides because it will be a very big hazard for the person's health. Run offs from pesticides and fertilizers can get into water, which can poison a water supply. Herbicide tolerance is effective because, plants that aren't engineered with herbicide tolerance require weeds to be removed, which costs lots of money and takes up lots of time. Disease resistance is an advantage because there are many viruses and fungi, scientists are working to create plants that can fight against these diseases. Cold resistance is an effective advantage because often times on farms there is unexpected frost which will kill some crops instantly. The way cold resistance is applied to plants is a gene from a cold water fish is taken and put into a crop. ...read more.

Conclusion

Genetic engineering makes it possible for farmers a lot faster and with much better nutrition and quality at a much lower cost. There are some criticisms to genetically modified foods, but even with those risks and hazards present, without genetically modified foods the world would be in bad shape for the future. The world's population is growing at a faster and faster rate, and the world needs ways to have food with proper nutrition. Criticisms that are against genetically modified foods are unintended harm to other species. The unintended harm comes from the genes is some crops that cause some insects to die. You must ask yourself this question though, whats more important, the loss of many human lives from malnutrition, or some insects dying from genetically modified foods? All the reasons above are why I support genetically modified foods, I think that in the future scientists will make more discoveries about foods that will help the world. We will have better quality food, more quantity of food, and the people will be a lot healthier. ...read more.

Another major threat to the capybara is hunting by humans for meat and oil from the subcutaneous fat, which is a popular medicine in southern South America (distribution of capybara shown left http://en.wikipedia.org/wiki/Image:Capybara-range.png ). The hides are used to make gloves, belts, leatherjackets, handbags, harnesses and saddles.

    This also implies that living organisms are to be tested on, and accidentally produced defect organisms are produced that need to be terminated, which can be unacceptable for some groups of people. This again raises ethical issues. One of the biggest concerns is that new toxins and allergies can be formed through genetic engineering.
