This is not a partisan effort, nor is concern about global warming confined to "environmentalists." This march will include hunters, fishermen, and farmers; hikers, bikers and birdwatchers. We are students and businesspeople, sugarmakers and ski-lift operators. We are parents and grandparents, and young people facing lifetimes on a warming planet. We are people of faith, and secular people devoted to the common good. Indeed, we have all been moved in recent weeks by the efforts of our retiring independent Senator Jim Jeffords, who has introduced legislation on global warming that goes further than any previous effort to really grapple with this problem. One of our aims is to make sure that his principles—an 80 percent reduction in carbon emissions by 2050, 20 percent renewable power by 2020, and cars that get at least 40 miles per gallon—prevail on Capitol Hill.
