It really is a shame that communists cloak themselves in these sorts of good intentions because we all want clean air and rivers, obviously, only a psycho wouldn't. It's such an effective trogen horse for them because it's obviously a good thing and it's very difficult to imagine how to accomplish it without empowering the state. So if empowering the state is your aim it makes a lot of sense to ride in the Trojan horse of environmentalism. It's kind of an all communists are environmentalists but not all environmentalists are communists sort of thing... (of course not literally all, just almost all)
