That's an easy thing to say, but not really accurate. Even without capitalism, we've wiped out entire animal populations. We're just doing it a lot faster now. Even if we were fully socialist, and there was no profit being made for anyone, our own humanity would be destroying the ecosystem; strip mining would still happen under perfect communism (e.g., not authoritarian states).
Capitalism and communism both need to same resources, they're just distributed different.
