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.

The idea that the Lord had given us a present, that the world is a gift from God... well, the amount of stuff, back then, that the Lord was giving away was limited. We do not have dominion.

It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.

I've never actually met one in the wild, but I have seen a king cobra. They go towards people, they rear up six feet tall and they're very aggressive and they are very fast. And one bite means certain death. So if I encountered a king cobra in the wild I would be very alarmed.

Dealing with global warming doesn't mean we have all got to suddenly stop breathing. Dealing with global warming means that we have to stop waste, and if you travel for no reason whatsoever, that is a waste.

I'm no longer sceptical. I no longer have any doubt at all. I think climate change is the major challenge facing the world.

Bringing nature into the classroom can kindle a fascination and passion for the diversity of life on earth and can motivate a sense of responsibility to safeguard it.
