Based on your readings about Bt corn, express your opinion about whether or not farmers should continue planting Bt corn. Explai
nataly862011 [7]

Answer:

Although it is controversial topic, it is not a recommended practice among socienty to cultivate BT corn when alternative methods of increasing plant yield are already available. On the other hand, scientists are encouraging more research on genetically modified (GM) solutions with lesser/reduced impact on ecosystem.

Explanation:

Although, cultivating BT corn helps improving the yield, reduce insecticides usage, and enhance the grain quality, it has been extensively debated to reduce this practice globally. This is because of severals reasons. At first, cultivation of BT corn affects non-target organisms that interact with the plant for symbiotic or neutral reasons including pollination. Due to genetic modificaitons, BT corn produce BT-proteins that kills the non-target organism. Secondly, it increases the insect resistance and those insects which survives even after chewing plant tissues of BT-corn, they are found to have resistance against several toxins at high doses. Once these chemicals enters the food chain, they could be extremely toxic to other naturally growing organisms.

Prince Charles stated that use of GM plants is disaster and should be banned immediately. Likewise, he said that it is also impacting the climate change. On the other hand, Prof. Smith showed a contradictory opinion and said that the views of Prince Charles are saddening. He is seeing the one sided picture only. He should ask for extensive research rather discouraging this aspect of modern science.

In my opinion, I would also say that the technology should be improved and make more eco-friendly rather than complete abolishing especially when the apparent benefits are greater than the harmful effects.
