Democrats stress environment in campaign tours

Democratic presidential rivals Hillary Rodham Clinton, Barack Obama and John Edwards campaigned separately in the early voting state of Iowa, urging thousands to make environmental protection a top campaign issue. They marked Earth Day by promoting proposals they said would increase energy conservation and cut down on pollution. "Today is Earth Day, and I personally believe every day should be Earth Day," Clinton said Sunday. "We have a duty to protect God's creation and we have a responsibility to repair the damage that we do as we go on in life."
