I had a wonderful teacher about animal behavior - my dog Rusty. He taught me that animals have personalities, minds, and feelings.

I shouldn't have named the chimps. It wasn't scientific. I didn't know. I knew nothing. And worse sin of all was that I was ascribing to them emotions like happiness, sadness and so forth.

I was even accused of teaching the chimps how to fish for termites which I mean that would have been such a brilliant coup.

It was because the chimps are so eye-catching, so like us and teach us so much that my work was recognised worldwide.

If you consciously say 'I won't do it!' to yourself, then you have a good chance that you won't.

Every individual matters and has a role to play in this life on Earth.

It's been proven by quite a few studies that plants are good for our psychological development. If you green an area, the rate of crime goes down. Torture victims begin to recover when they spend time outside in a garden with flowers. So we need them, in some deep psychological sense, which I don't suppose anybody really understands yet.
