I am quite surprised to see this default-to-no-action comment here on HN. Sometimes, a problem isn't your fault, but you are still compelled to fix it. If people have this attitude, then "we" (as a species) are absolutely screwed vis-a-vis climate change. In a generation, nobody is going to be around who did all the polluting, and hopefully everyone doesn't just sit around saying "Well I didn't do it!"
