The more you go on, the less you need people standing between you and the animal and the camera waving their arms about.

Instead of controlling the environment for the benefit of the population, perhaps we should control the population to ensure the survival of our environment

Can a growing human population still leave space for wildlife?

I'm not a propagandist, I'm not a polemicist; my primary interest is just looking at and trying to understand how animals work.

I'm absolutely strict about it. When I land, I put my watch right, and I don't care what I feel like, I will go to bed at half past eleven. If that means going to bed early or late, that's what I live by. As soon as you get there, live by that time.

I think the most alarming animals I have encountered are really poisonous snakes.

The only acceptable way to solve ecological problems is if you can persuade people to have fewer children. In the Victorian times, there were families of 15 children. Someone like Edward Lear, he was the last of 21 children. And so what we have to think about is offering people the alternative choice. And in the West, that's what's happening. The birth rate has been dropping steadily and still is. I'm wanting human beings to be better off so they don't view children as an insurance for the future.
