As far as I'm concerned, if there is a supreme being then He chose organic evolution as a way of bringing into existence the natural world... which doesn't seem to me to be necessarily blasphemous at all.

I have no doubt that the fundamental problem the planet faces is the enormous increase in the human population

If we were all to reduce our demands for energy, it would make an enormous amount of difference.

I don't think whole populations are villainous, but Americans are just extraordinarily unaware of all kinds of things. If you live in the middle of that vast continent, with apparently everything your heart could wish for just because you were born there, then why worry? [...] If people lose knowledge, sympathy and understanding of the natural world, they're going to mistreat it and will not ask their politicians to care for it.

All our environmental problems become easier to solve with fewer people and harder - and ultimately impossible to solve - with ever more people.

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.

Natural history is not about producing fables.
