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 swanning round the world looking at the most fabulously interesting things. Such good fortune.

I can mention many moments that were unforgettable and revelatory. But the most single revelatory three minutes was the first time I put on scuba gear and dived on a coral reef. It's just the unbelievable fact that you can move in three dimensions.

I'm a humanist. I'm neither one side nor the other.

Can a growing human population still leave space for wildlife?

I mean, it is an extraordinary thing that a large proportion of your country and my country, of the citizens, never see a wild creature from dawn 'til dusk, unless it's a pigeon, which isn't really wild, which might come and settle near them.

Now, I find that very difficult to reconcile with notions about a merciful God.
