Genetic modification of basic food-and-fuel crops: basically all

In case you haven’t been keeping track, virtually all corn, cotton, and soybeans (and sugar beets not on this graph) are genetically modified. 

Not only that, but they take up more than half of all cropland in the United States.

And half the corn is used to fuel automobiles.

Monoculture, control of the food supply, and lack of biodiversity, anyone?
