The precautionary principle is probably THE best all-encompassing argument to act in the face of climate change.
For those interested in further exploring this argument, and for great short movies on the issue of risk management, please see The Manpollo Project (http://www.manpollo.org/). As for the argument that nature will survive - of course it will. That is why it is wrong to say that we want to save the planet. The planet will take care of itself - in its own time frame of 1000s and millions of years. The issue is about us, and our children. And about our responsibility to take care of our home. Maiken
