Environmentalists assume that environmental change caused by humanity is bad, but that much larger 'natural' changes are neutral. This is because they often suffer a 'naturalist fallacy' or "appeal to nature". Because natural is defined as good in their eyes, they can't imagine a bad natural change. In contrast, every man-made change is assumed to be bad, even when the man-made change improves the environment.
This leads to anti-human, anti-environment policies. e.g. Calls for bans against: fishing, genetic engineering, plastic bags, nuclear power, fossil fuels, factory farming, 'chemicals', including pesticides, herbicides, and fertilizers. Greens propose: organic farming, natural energy such as renewable energy systems: wind-, solar-, hydro-, geo-, bio- energies. Every green solution is worse for the environment than the technologies it is designed to replace. Because greens long ago abandoned cost benefit analysis for the 'precautionary principle' they can't even know whether their proposals make sense. Perhaps this may explain why their policies are senseless and they attract so many incompetents to their ranks?
The green sense of moral superiority (rarely made explicit) is often glanced through their outrage against perfectly good technologies which benefit the environment, such as fossil fuel burning. Giving up on cost-benefit analysis means the give up on basic evidence too. This moral superiority is misplaced, and is really outrage against humanity for living so well and improving our lot.
