Environmentalism poses a problem for libertarian ideology/environmentalists
From Critiques Of Libertarianism
The short of is that environmentalists totally smash open the idea that property rights theories can really account for who is permitted to do what with the land that they own. Almost all uses of land will entail some infringement on some other piece of land that is owned by someone else. So how can that ever be permitted? No story about freedom and property rights can ever justify the pollution of the air or the burning of fuels because those things affect the freedom and property rights of others.
