With genetically modified organisms, traits are selected for, but not in the historical sense. They're selected from a menu of desired features. "Oh, well, hmm...these red beets could be a bit more...golden! and uh... plump! and could I add some more sugar?" I imagine this is what industrial farmers say. Of course, the Green Revolution feeds many more people than traditional agriculture can, but at a cost to nature and a long-term risk for people.
GMO's are plants too. And plants reproduce, something they're are quite good at after doing it for millions of years. To survive, they have evolved -through natural selection- neat and sometimes tricky ways of reproducing. So, when GMO's are planted near non-GMO's, there is a high chance of cross pollination. In that case, GMO's contaminate non-GMO's. Natural crops with one set of features are contaminated by GMO crops with a completely different set. The chances increase of a genetic monoculture, whereby GMO's would completely dominate another crop, leaving only themselves. I won't argue about whether GMO's are fundamentally evil, or about Monsanto, or the 1980's legislature declaring life patent-able, but I will say that mono-cultures scare me. If we rely on mono-cultures for our bananas and turnips, not only do we risk those mono-cultures being wiped out by a single disease: our food becomes boring! On an end note, we eat ONE type of banana in the U.S., while Indians have a selection of about 300 different types of bananas.
