Actually, the capitalist point of view is that the government destroys the environment by regulation and government ownership of land. The basic argument is that it is easy to get away with polluting land that is not privately owned because the government is too big and slow to really stop it. Because it is public land, no one really takes responsibility for it and there's no immediate victim. Capitalism advocates private ownership of land, in which case pollution would not be as big of a problem because it would be damaging private property, and the owners of that property would be better able to take legal action against the polluters than the government.

That's the theory at least...
