We are in a fool's climate, accidentally kept cool by smoke, and before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.

Climate change now represents so urgent a threat to mankind that the only way to deal with it is by suspending democracy.

Only nuclear power can now halt global warming.

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.

Only rarely do we see beyond the needs of humanity, and he linked this blindness to our Christian and humanist infrastructure. It arose 2,000 years ago and was then benign, and we were no significant threat to Gaia. Now that we are over six billion hungry and greedy individuals, all aspiring to a first-world lifestyle, our urban way of life encroaches upon the domain of the living Earth.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

There is no clear distinction anywhere on the Earth's surface between living and nonliving matter. There is merely a hierarchy of intensity going from the 'material' environment of the rocks and the atmosphere to the living cells.
