My suggestion is that we should first work to ensure the Third World has clean drinking water and sanitation.

I found university a little dispiriting. I thought I would enter the great halls of Plato, but instead I entered the halls of an intellectual sausage factory. I wanted to do something not on the main course, and chose the environment.

The Kyoto treaty has an estimated cost of between US$150 and $350 billion a year, starting in 2010.

I really try to say things as they basically are and it so happens that it is a good message that things are getting better, but there are still problems.

I tentatively believe in a god. I was brought up in a fairly religious home. I think the world is compatible with reincarnation, karma, all that stuff.

Think on a 50-year scale, which is a much more natural time-scale for global warming. The US is right now spending about 200 million dollars annually on research into renewable energy.
