First, it seems to me that many of the crucial issues of modern environmentalism are not amenable to broad-based moral reasoning and intuition that religion can provide. Religious thinking has little to say about, for example, what is the appropriate amount of particulates that should be in the air, or whether climate change should be tackled by cap-and-trade, or a carbon tax, or command-and-control regulation.
Second, it concerns me to sugges that one cannot be a good Jew/Christian/Muslim/anything else and have a particular position on the environment. The environment is a political issue, and it should be. But that begins to move us toward a political test of religious commitment.
It's worth reading the whole thing.
That is a Jewish perspective -- do other perspectives differ? What about Christians? Buddhists? Muslims? Pagans?
