Apart from anything else, I am designed by evolution, like we all are: if we see a little thing like that, big eyes, tiny nose, we go 'aaah'. That's what evolution does. We are programmed to do that. So to find babies the most amazing, isn't surprising, I don't think.

No one will protect what they don't care about, and no one will care about what they have never experienced.

There is no question that climate change is happening; the only arguable point is what part humans are playing in it.

I find it far more awesome, wonderful, that creation; our appearance in the world; should be the culmination, or at least one of the latest products of 3,000 Million years of organic evolution, than a kind of country trick, taking a rib out of a man's side in a trance.

You've got to be fairly solemn [about the environment]. I mean the mere notion that there are three times as many people on Earth as there were when I started making television. How can the Earth accommodate them? When people, including politicians, set their faces against looking at the consequences-it's just unbelievable that anyone could ignore it.

I'm not an animal lover if that means you think things are nice if you can pat them, but I am intoxicated by animals.

Many individuals are doing what they can. But real success can only come if there is a change in our societies and in our economics and in our politics.
