PRI’s The World (can you tell what I listen to regularly?) ran a nice story on the efforts of some Islamic scholars to emphasize the religion’s emphasis on conservation.  This runs parallel to similar efforts among Catholics and the American evangelical community.  I’ve often pointed out to my students that I cannot identify a major religion that encourages its adherents to crap on the poor.  Seems I can extend that argument to say that most religions, in some way or other, encourage their adherents to use the world wisely*.
*There are significant objections to environmentalism in some parts of the evangelical community, but most of these objections are not pitched against the idea that we should use the environment wisely.  Instead, they are political arguments concerned that a focus on environmental issues will draw people away from an attention to core theological ideas.
