The worst threats to the environment are green Luddites, global warming ideologues and small-d democrats. The more advanced a technology is, the less harmful it generally is, including nuclear power. Global warming is a good excuse to ignore all other environmental concerns, and if the worst predictions are true, stopping all greenhouse gas emissions is insufficient. Emergency measures to reverse global warming would be necessary. Most of all, we need strong, rational, honest government. So-called democracy is incapable of taking the draconian measures necessary to save what is left of the natural world.
