The awful thing is we don't respect each other.

I never wanted to give up. I thought I might have to. Especially at the beginning when chimpanzees had never seen a white person before.They gave one look at me and ran away! They were scared, but eventually I got their trust.

The cheapest and most efficient way of slowing down global warming is to protect and restore the forests, particularly the tropical forests

It's not Africa that is destroying the African rainforest, it's selling concessions to timber companies that are not African, they are from the developed world - Japan, America, Germany, Britain.

The tree I had in the garden as a child, my beech tree, I used to climb up there and spend hours. I took my homework up there, my books, I went up there if I was sad, and it just felt very good to be up there among the green leaves and the birds and the sky.

I urge you to read Eternal Treblinka and think deeply about its important message.

Chimps are far too much human to be my favorite animal.
