The question is, are we happy to suppose that our grandchildren may never be able to see an elephant except in a picture book?

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.

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.

The World is full of wonders, but they become more Wonderful, not less Wonderful when Science looks at them.

I'm against this huge globalisation on the basis of economic advantage.

We really need to kick the carbon habit and stop making our energy from burning things. Climate change is also really important. You can wreck one rainforest then move, drain one area of resources and move onto another, but climate change is global.

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.
