Yes, I agree the risks of GM foods may not have been studied enough and that reduction in plant variety is an issue. But, to feed almost 9,000,000,000,000 people, many of whom do not have as much money as we do, food production capacity has to be increased dramatically, and GM food allows that. So, one benefit is less hungry people worldwide, at lower prices.
There are other benefits, like higher resistance to diseases and less pesticide usage.
I am not a food expert, but both sides of any technology ( and that is what I call GM food ) have to looked at. Sometimes benefits outweigh drawbacks, as may be the case here, or may be not. Like global warming, some countries, like Canada, benefit.
I need to hear more from both sides to be convinced that drawbacks outweigh benefits. Perhaps rich Westerners lose but poorer Africans or Asians win ?
I need more facts.
