Environmental activism was already nasty and lethal when I wrote Eco-Imperialism: Green Power--Black Death 18 years ago. It's gotten steadily worse since then, especially with hysteria about the "looming manmade climate apocalypse" driving ever more extreme demands that we rid the world of fossil fuels and prohibit or roll back modern living standards.
The demands have reached previously unimaginable extremes--based primarily on GIGO computer models and wild assertions about planetary temperatures, weather, icecaps and vanishing wildlife. The claims have little basis in real-world evidence, but are presented as Gospel Truth by climate alarmists.
