Pollution and global warming are two separate things we both need to prevent. We do not need to choose, we can and should address both. In Western countries pollution is generally better contained/addressed/regulated than in poorer countries, however Western countries contribute hugely more greenhouse gasses (certainly per capita, and especially US and AUS) than poorer countries. So no, carbon is not the wrong thing. It is the primary, singularly most important things we should address. And indeed, as long as we don't put a properly high prico on it one way or the other we are just fooling around and making the earth that much less inhabitable for our children
