We have domesticated crops over a very long period of time, like tens of thousands of years. And crops get - seeds get carried. Sometimes, if they're very small seeds, they get scattered off trucks. Pollen travels.

For me science is not different from art, except in the one small, crucial detail that experiments speak their own truths, not ours.

One of the really remarkably beneficial aspects of genetic engineering is that much of the previous methodology for controlling pests and so forth is through chemicals that affect a very broad spectrum of insects, for example, or fungicides that control fungi.

If everybody switched to organic farming, we couldn't support the earth's current population - maybe half.

We need to continue to decrease the growth rate of the global population; the planet can't support many more people.

Weeds do become resistant to herbicides, and it needs to be managed with multiple herbicides.

In many places in the developed world, we eat or waste probably twice as many food calories as we really need. We're wasteful of food. We ship all over the world. We're now realizing that generating the energy to ship the food around the world is also ruining our climate.
