Which religion, if any, best supports an environmentally sound lifestyle?
Buddhism.
I know Pagans who are very oriented towards environmentally sound practices. But I've also met a few that aren't (imo). For example, I've met Pagans who don't believe in birth control because they believe that it's "unnatural" and that new life is inherently good. Just because one's spirituality is earth-centered doesn't
necessarily mean that one's lifestyle will be environmentally sound.
UUs are big on environmentalism, like Pagans (in fact many of the greenest UUs that I know are pagan UUs). But UUs are big on a lot of social justice issues and while environmentally sound practices may be a top priority for some UUs it isn't for all. Btw, I personally do not feel that going to the Green Festival once a year and buying "green" products by itself constitutes an environmentally sound lifestyle.
Buddhism, otoh, is rooted in the belief in interdependancy (we UUs got that from Buddhism). At its very basis Buddhism is aware of how the actions in one location have consequences on a much larger scale. The ideal Buddhist lifestyle is modest, sparce, almost ascetic by our standards.
Generally the UUs and Pagans that I know approach environmentalism from a consumerist attitude - buy "green" and recycle. In Buddhism the ideal is to buy less in the first place.
Plus, I just know a lot of green activists who are Buddhists.
