Is Sustainability different than Environment?

This forum is for discussing those issues that relate specifically to sustainability. As opposed to Environment which would (as some recent books and movies suggest) exist just fine without humans, Sustainability discussions typically revolve around what we as a human society can or should do if we want to sustain ourselves as a species or at least in some semblance of the societal standards we've come to expect. Obviously the 2 concepts are related. As they are to many other areas on this board. For a good discussion see the Wikipedia entry at What are your thoughts on sustainability these days? Is it important to you and your family? What should we be doing in Evanston or this Neighborhood for a more sustainable future?
