Protection under the Endangered Species Act will provide concrete help to polar bears and could revolutionize American climate policy. Since U.S. resistance to curbing greenhouse gases has allowed other countries to shirk their responsibilities as well, major changes in American policy are likely to have a powerful domino effect, catalyzing change in climate policy worldwide.
From polluting power plants in the Midwest to auto manufacturers, a vast array of industries may have to clean up their acts to give the polar bear a chance to survive.
