It is easy to feel powerless because "everyone else" is making it so much worse than me, why bother, but I prefer the adage "Don't curse the darkness, light a candle". There are obvious reasons why massive economies won't just replace factories etc. with cleaner tech so instead, those of us who really care should be developing the tech that drives this. Invent an amazing wind turbine or clean battery and let the Chinese and whoever else buy it up to clean up their country! This isn't just for pollution though. If you think that you can do policing/government/privacy/transport/whatever better then do it and let all the other countries copy you :-)
