Genetic Modification - Good and Bad?

Extracts from this document...


Genetic Modification - Good and Bad The British Medical Association defines genetic modification as "The Process of altering genetic material to express different characteristics." Genetic modification is not a new concept it has been occurring for many years through the basic method of selective breeding. I will now look at the phrase Genetic Modification. To modify something means to change it in some way, the reason to change something is to provide us with benefits, Modifying genetics in animal is not a new concept, but modifying plants is. As scientific technology has progressed GM has become more specific, scientists can now alter just one gene in an animals body. My knowledge of this subject is very small; before I venture into this essay with my opinion that Genetic modification is a good thing, it increases crop yield, strengthens countries economies and has the potential to save lives.(1) Genetic engineering evolves restriction enzymes to cut DNA at specific sequences to create "sticky ends" which will stick to other "sticky ends" made by the same enzyme. ...read more.


I argue however that any reduction is better in the use of damaging chemicals is better than none at all. In contrast to this the BMA stated in a recent report that the impact on genetic modification on agriculture, food and health that too much emphasis was being made on making crops resistant to the actual pest or weed leaving plants with increased amounts of insecticide and pesticide rather than making them resistant to the actual pest or weed leaving plants with increased amounts of insecticide and pesticide residue. There are concerns that pest-resistant crops will remove important food sources for wildlife, and the ecological impact of such crops certainly must be evaluated. One of the major benefits would be to be able to grow crops that were herbicide tolerant. This would allow farmers to use broad-spectrum herbicides that they would not normally be able to use, as they would harm their crop. An example is Soya that has been Genetically altered to make it tolerant to one kind of broad-spectrum herbicide that would kill non-GM Soya. ...read more.


There are many ethical reasons for the Genetic Engineering of crops, the main argument being if we have the technology to improve the quality of life of people in the third world by changing the genetics of a plant to make it possible to grow crops in arid areas and to increase the nutritional value of the plant. By making these modifications it would make it easier for third world countries to grow and sustain their countries basic dietary needs. After carrying out my research, I am still not completely for Genetic modification nor am I against. One main issue I have is that genetic modification has not been round long enough for us to investigate they full effects on our environment and ecosystems. As for the ethical issues I believe all GM foods should be labelled so that consumers have the choice to eat what foods they wish. I do not believe that Genetic Modification will cause to many biological problems, I believe the greatest problem of all is they way in which humans use Genetic Modification. Over all I think GM crops are a good thing. ...read more.
