There are more obese people in the world than starving people. As China and India start to develop our eating habits - and not by accident but because agribusiness is going over there and imposing our habits on them - if the population doesn't increase at all, we'll have to raise twice as many animals as we do.

I tried to think about other things. I tried to invent optimistic inventions. But the pessimistic ones were extremely loud.

Everything is to protect you. I exist in case you need to be protected.

Things were happening around us, but nothing was happening between us.

Just to be a functioning adult in the world, we develop all of these layers of protection. When we see homeless people, we don't cry, even though homeless people probably deserve our tears - you know, it's a horrible thing.

I know lots and lots and lots of vegetarians who think it's perfectly all right to kill animals for food to eat, but don't do it because they think all the ways in which it's done are wrong.

Factory farming, of course, does not cause all the world's problems, but is is remarkable just how many of them intersect there.
