Did Tolkien ever think of environmental implications when Saruman destroyed all trees

I think he did. He thought that modern world was ugly (in one article he says that there are no modernn houses which are beautiful and etc.) I think he was concerned with ecology problems. And the regime of Saruman in the Shire is also agressive to nature. If society is totalitarian, e.g. evil, it is evil in all aspects and it is equally destructive towards both people and nature
