I think we're lucky to be living when we are, because things are going to get worse.

I'd like to see the giant squid. Nobody has ever seen one. I could tell you people who have spent thousands and thousands of pounds trying to see giant squid. I mean, we know they exist because we have seen dead ones. But I have never seen a living one. Nor has anybody else.

The whole of science, and one is tempted to think the whole of the life of any thinking man, is trying to come to terms with the relationship between yourself and the natural world. Why are you here, and how do you fit in, and what's it all about.

The process of making natural history films is to try to prevent the animal knowing you are there, so you get glimpses of a non-human world, and that is a transporting thing.

In the West, that's what's happening. The birth rate has been dropping steadily and still is. But there is still a vast amount of the world where that's not the case. And that is where the big population growth is taking place.

I would love to go and see the Himalayan Mountain Kingdoms. There are very few left now. I would loved to have gone to Tibet and Nepal. And there are still parts of central Asia that are utterly unexplored.

We can now destroy or we can cherish-the choice is ours.
