 Governments traditionally have been the problem when it comes to environmental protection. I again offer you, the communist world, the mega political states that were the dirtiest states in history. If you took the train from the west to Berlin, you could tell when you crossed the Iron Curtain. You didn't need the police dogs. All you had to do was see the degraded infrastructure and the smoke-belching trabonts. That was East German's people's car. So the air was really degraded in the communist world. And in the third world, where neither communism nor capitalism, just very few viable organized economies, it's horrible. People die young deaths from lung disease because they cook with dung indoors. Don't you think it would be nice to foster environmental protection by helping them become affluent with free markets? That's the moral case for libertarianism right there.
