QUOTE : If collective action resulted in just one fewer devastating hurricane, just a few extra years of relative stability, it would be a goal worth pursuing. In fact, it would be worth pursuing even if it had no effect at all. To fail to conserve a finite resource when conservation measures are available, to needlessly add carbon to the atmosphere when we know very well what carbon is doing to it, is simply wrong. Although the actions of one individual have zero effect on the climate, this doesn't mean that they're meaningless. Each of us has an ethical choice to make. During the Protestant Reformation, when "end times" was merely an idea, not the horribly concrete thing it is today, a key doctrinal question was whether you should perform good works because it will get you into Heaven, or whether you should perform them simply because they're good--because, while Heaven is a question mark, you know that this world would be better if everyone performed them. I can respect the planet, and care about the people with whom I share it, without believing that it will save me.
