What are our personal obligations toward the environment?

That is such a hard question to answer. The freaks tell you to go back to the stone ages. The freaks on the other end dare not even entertain the question. In the end, most people are stuck at a relativistic position that roughly translates to setting the bar at precisely the lifestyle that they themselves are leading. It's not unlike the law of driving "Anyone who's driving slower than me is an idiot, and anyone faster is a maniac". This is when the economists' detached unemotional approach is so refreshing to read. Found this really interesting. The comments are great too.
