Climate change is no longer America's chief environmental concern. According to a New Washington Post/Stanford University poll, 29-percent of Americans consider water and air pollution to be America's biggest environmental problem, compared with only 18-percent now worried about global warming. That's down from 33-percent in 2007. It means 8 in 10 Americans aren't concerned about global warming.
