Grethe asks, on behalf of the future occupants of Earth:
How come we, in the so-called industrial world, are so unwilling to lower our demands for unnecessary and luxury goods, even though we know that we cannot continue to consume as we do now if coming generations shall have an inhabitable Earth to inherit?
My thought is that many of us do not realize the impact of our individual actions. We believe that what we want isn't so much. It's the "other guy" who is greedy.
