The reason my food bank is vegan is because I can't pay for animal products in good conscience.

I was very concerned about helping animals improve their situations. But that was out of love. It wasn't political or out of a belief that animals had rights.

I feel so guilty when I see orcas performing their stupid tricks in their little swimming pools, and when I see circuses or elephant abuse. I don't want to be in the same industry with these people.

Through PETA, we rescue animals in roadside zoos and circuses. They are some of the most abused animals in the country.

In the pressure cooker of a TV show, it’s a little bit of a witches’ brew. I completely think I’m capable of being crazy. I probably was crazy when I was doing 'The Simpsons'.

I want medical experiments on animals stopped. They don't do anything, and they don't work.

Veganism is an answer for almost every problem facing the world in terms of hunger and climate change.
