So-called 'sustainable development' is meaningless drivel.

A billion could live off the earth; 6 billion living as we do is far too many, and you run out of planet in no time.

I think that we reject the evidence that our world is changing because we are still, as that wonderfully wise biologist E. O. Wilson reminded us, tribal carnivores. We are programmed by our inheritance to see other living things as mainly something to eat, and we care more about our national tribe than anything else. We will even give our lives for it and are quite ready to kill other humans in the cruellest of ways for the good of our tribe. We still find alien the concept that we and the rest of life, from bacteria to whales, are parts of the much larger and diverse entity, the living Earth.

Nowadays if you're dependent on a grant - and 99% of them are - you can't make mistakes as you won't get another one if you do.

I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while.

If a power station were to be built down the road, I'd prefer a nuclear plant over an oil burner, and definitely over a coal burner. We simply have to lessen our consumption of fossil fuels.

Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades.
