If a fundamentalist, right-wing Christian can come up with the best justification for legalizing (not decriminalizing, but full-on legalization) of marijuana, I have to believe it's possible. Genesis 2:15 says "The Lord God took the man and put him in the garden of Eden to work it and keep it." Note the KEEP it part. Numbers 35:33 says "You shall not pollute the land in which you live, for blood pollutes the land, and no atonement can be made for the land for the blood that is shed in it, except by the blood of the one who shed it." Apparently, there's already a fundamental religious case for environmental protections.
