A new holy war is growing within the evangelical community, with stakes for the Earth and American politics. For over a decade liberal Christians have made the environment a moral commitment. Now some conservative evangelicals as well are standing up for the Earth as a Biblical imperative of stewardship. From a dynamic conservative church in Boise, Idaho, to an evangelical activist group known as "Christians for the Mountains"in West Virginia, grassroots believers are speaking out. So are some conservative evangelical leaders at the national level who have called for action to stop global warming. But they are being met head-on with opposition from religious right political figures like Jerry Falwell and James Dobson, who are pillars of the right-wing coalition that adamantly supports the Bush administration in downplaying the threat of global warming. The political stakes are high: three out of every four self-identified white evangelical voters cast their ballots for George W. Bush in 2004. The program explores how a serious split among conservative evangelicals over the environment and global warming could reshape American politics.
