I agree. The rich are the main problem, and that should be top priority. But that also shouldn’t be used as an excuse to not improve oneself personally. My suggestion is that people shouldn’t worry about aiming for personal idealism, but should just make a conscious effort to be less environmentally damaging than their peers, their family, work colleges, and friends. If a person achieves that, then they can be confident that they are not the problem.

[edit] Obviously if everyone did what I’m suggesting then it would be a kind of race-to-the-bottom. But that’s not happening. If it was, then we wouldn’t be in this mess in the first place. All I’m suggesting is a rough heuristic for what’s reasonable for an individual to do on their own.
