There is no question that climate change is happening; the only arguable point is what part humans are playing in it.

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

There's a small worm called Loa Loa Filariasis. This parasite can survive in one environment exclusively- namely, underneath the skin and inside the eyes of human beings. Children and the elderly in tropical regions (usually the poorest) are the most widely affected. A painful, slow death is virtually certain. The worm can actually live in the host for 17 years before the host finally dies.

Getting to places like Bangkok or Singapore was a hell of a sweat. But when you got there it was the back of beyond. It was just a series of small tin sheds.

It is that range of biodiversity that we must care for - the whole thing - rather than just one or two stars.

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.

Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.
