Based on your readings about Bt corn, express your opinion about whether or not farmers should continue planting Bt corn. Explai
miss Akunina [59]
Farmers should discontinue the use of Bt corn (genetically modified maize)as their negative affects on the health of the consumers have not been fully over ruled by the recent research. In my opinion, genetically modified crops, although, are resistant to various pests, should not be encouraged because of the toxic chemical contents used during their production. There's a strong likelihood of these toxic chemicals entering our food chain and also being harmful to other naturally growing plants, hence there's a need for more research before this idea is pursued.
