But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.

In what terms should we think of these beings, nonhuman yet possessing so very many human-like characteristics? How should we treat them? Surely we should treat them with the same consideration and kindness as we show to other humans; and as we recognize human rights, so too should we recognize the rights of the great apes? Yes.

Even chimps understand the concept - if a troop of chimps enters a fruit tree, they will only pick the fruits that are ripe and leave the others growing. That is sustainability.

Our brain is almost the same as the chimps', but we have language, we have electronic communications, we've put people on the moon - we are immensely more intelligent. And yet: how come the being with the most extraordinary intellect ever is destroying its only planet?

I was the sort of person who didn't care about hairdressing and clothes and parties and boyfriends. I really wanted to be in the wild.

Become as knowledgeable as possible.
