Q: Why are GMOs so controversial?

Proponents of GMOs note that most studies on the products (including corn, soybeans, sugar beets, dairy products, cotton, papayas, and zucchini) have deemed them safe for human consumption. They point to benefits like more-efficient food production and superior nutritional content or taste.

Critics say that most studies on GMOs are short-term and that the long-term effects are unknown. Even the short-term risks are still not fully known, they say. More needs to be done to determine possible effects on human health as well as on the environment, including the evolution of "super pests" that could devastate sustainable agriculture.


Some critics advocate a total ban on GMOs; others call on more oversight of the industry, including labeling of foods containing GMOs, until more data is collected.

Q: What is the US position on GMOs?
