Neel Sheth- Genetic Engineering on Food
Genetic engineering, a practice commonly utilized on food, is the manipulation of an organism's gene makeup through the use of biotechnology. In 1994, the first genetically modified food, the Flavr Savr Tomato, was approved for release. In the 25 years since then, the prevalence of GMO's has increased each year. GMO's are useful from an economic standpoint, as crop yields are greatly increased from the new genetics. However, genetic engineering can have negative effects, such as, a lack of biodiversity, ecological risks, and human health risks.
One example of a negative consequence of GMO production is the lack of biodiversity. Genetically modified different species of plants can cause some of these species to become invasive. Because much of the genetic engineering field is an unknown quantity, many of the results can't be predicted with 100% accuracy. For example, a plant may pass a lab inspection and be deemed safe to be planted or grown in an actual environment (as opposed to in a lab). However, if something goes wrong, the plant may be inedible, or even deadly, to species that used to eat it, throwing off the food web and causing destruction of other species in certain cases.
In addition, an ecological risk that results from the production of genetically engineered crops is the increased use of insecticide and pesticide. Scientists will develop plants that are more resistant to insecticide, pushing farmers to spray more on their yields. As a result, insects may develop a stronger and faster resistance due to the increased exposure to insecticide, which causes even more to be sprayed. Overall, this results in more pollution due to the increased insecticide, more companies selling these chemicals to farmers, and more insects becoming resistant to the very product meant to harm them.
So, the question must be asked: is it worth it to support the genetic engineering of different organisms? Despite the positive economic gains, negative environmental and ecological effects persist, and it is up to us, the consumers, to decide whether or not we want to support it.
Questions to consider:
Are the economic benefits of GMO's worth the risks?
Are GMO's necessary to keep food supply up as human population increases?
Are generically engineered foods more appealing to you because they "taste better"?
Is the higher cost of organic foods worth it?
