There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

The entire range of living matter on Earth from whales to viruses and from oaks to algae could be regarded as constituting a single living entity capable of maintaining the Earth's atmosphere to suit its overall needs and endowed with faculties and powers far beyond those of its constituent parts.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

Only nuclear power can now halt global warming.

The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

The big threat to the planet is people: there are too many, doing too well economically and burning too much oil.

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.
