I've been bitten by a python. Not a very big one. I was being silly, saying: 'Oh, it's not poisonous' Then, wallop! But you have fear around animals.

If you watch animals objectively for any length of time, you're driven to the conclusion that their main aim in life is to pass on their genes to the next generation.

All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.

Its about cherishing the woodland at the bottom of your garden or the stream that runs through it. It affects every aspect of life.

That people will object very much to seeing a predator killing its prey, and yet, in the news, will accept showing shots of people shooting one another.

What humans do over the next 50 years will determine the fate of all life on the planet.

I'm luckier than my grandfather, who didn't move more than five miles from the village in which he was born.
