Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?

I don't think that faith, whatever you're being faithful about, really can be scientifically explained. And I don't want to explain this whole life business through truth, science. There's so much mystery. There's so much awe.

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

I'm always pushing for human responsibility. Given that chimpanzees and many other animals are sentient and sapient, then we should treat them with respect.

And always I have this feeling--which may not be true at all--that I am being used as a messenger.

Certainly, if you look at human behavior around the world, you have to admit that we can be very aggressive.

My favorite animals are dogs.
