It's time to face facts: Most people stop being environmentalists when they sit down to eat.

To me, it is one world, and the non-human animals bear the brunt of oppression and suffering.

Today, I marvel at the vegan foods in the supermarket, at the cruelty-free clothing choices in stores, and at the fantastic alternatives to dissection in schools, the modern ways to test medicines without killing rabbits and beagles, the many forms of entertainment involving purely human performers.

Pigeons are gentle and smart and have complex social relationships. Their hearing and vision are both excellent.

The best bet for the horses would be to stop betting on the Derby and other horse races, and to stop breeding, racing and killing thoroughbreds altogether

I'm not only uninterested in having children. I am opposed to having children. Having a purebred human baby is like having a purebred dog; it is nothing but vanity, human vanity.

There's nothing humane about the flesh of animals who have had one or two or even three improvements made in their singularly rotten lives on today's factory farms.
