It is unclear who first invented the idea of GMO corn, but we do know that most farmers have been using this method on their crops for many years now. The genetically modified corn (Bt corn) was made for a very important reason, pests kept eating the corn on a farmers land. The corn is called "Bt corn" because a gene called bacillus thuringiensis was added to the genes of the corn grown, which acted as a defense system to repel pests from the corn crops.
Pros: Bt corn is immune to pests. Farmers can collect more corn because more corn will be untouched by pests. The corn will be healthier because no animals have harmed the corn.
Cons: Some people may have an allergic reaction to the corn due to the genes added. People consume a pesticide everytime they eat Bt corn. Beneficial insects are also killed by eating the Bt corn, such as honey bees.
In my personal opinion, I think Bt corn should be able to be used by all farmers becuase it is very beneficial to all people, despite the few cons. Corn is used in a very large amount of different food products, and Bt corn makes it possible for all of these productsto be made. Bt corn has no effect on the way the food tastes, or impacts the body. All people consume Bt corn whether they are aware of it or not. I dont see any problem with the use of GMO corn.
