James Lovelock

I imagine, like most people I became aware of the Gaia Theory—essentially that the all of the complex interacting systems that make up the planet can effectively be seen as a single large organism—before I knew of its originator, James Lovelock. Since then I've come to know his work more and while sometimes it can be tough to hear (only nuclear power can now halt global warming, 90% of human population will be killed off by 2100 due to the effect of rise temperatures), Lovelock is of such stature, and has such a long scientific track record that you have to consider seriously what he says. As an environmentalist, you can't afford not to pay attention to him, even if sometimes he sounds like a defeatist.
