LONDON -- Perhaps philosophers have a name for it -- this modern phenomenon of continuing to enjoy life in a way that we know is leading to destruction because we feel that there is nothing we can do about it anyway.

I am, of course, referring to the ecological crisis we are now in, which can only be resolved two ways: a revolutionary change in the way we live or the destruction of the world as we know it.

A year ago, British scientist John Houghton asserted that "our long-term security is threatened by a problem at least as dangerous as chemical, nuclear or biological weapons, or indeed international terrorism -- human-induced climate change."
