Sez you. We don't want it, you Americans will just have to eat it all yourselves. That shouldn't be a problem as you say it's so safe.
What about all the poor people in the world who would not be able to afford food if GM-modified foods weren't grown to boost the food supply to include them?
Do you want them to go hungry?
If not, how do you propose to produce enough food for them without GM? Reducing food waste? Feeding less grains and legumes to animals so that they can be consumed by humans instead?
What sacrifices are you willing to make with your food supply to compensate for reducing GM-produced food? Are you willing to eat less meat? Stop utilizing prepared-food services that cause more food waste as part of their business model for providing a variety of ready-to-eat foods that don't require customers to wait?
And furthermore, non-GM foods are more labor intensive to produce and process, so where does the extra labor and processing equipment come from for everyone to enjoy the luxury you have in affording to reject GM? Are YOU personally going to join the growing labor pool of agricultural and other food supply-chain workers needed to produce and distribute enough non-GM foods so everyone in the world can avoid GM?
Plus if you did go to work in agriculture or food-handling, you realize you would have to sacrifice many luxuries, including but not limited to free time and retirement - because how are you going to afford expensive organic food on agricultural/food-worker wages while also saving up money for the future?
