But it's also important to realize that even if Climate Change isn't man made pollution still is and we need to do our best to reduce it. It's not that simple. "Doing our best" to reduce pollution is a process that carries staggering costs of its own. It is not realistic to achieve a pollution-free lifestyle across all segments of humanity, so we're going to have to decide where the lines are drawn. That, regrettably, is always going to be a political process, and not a scientific one.
