Utah's Great Salt Lake has been in decline, owing to climate change, drought, and over-use of water resources, and is now one-third the size it was in the 1980s. A new scientific report warns that, without dramatic and immediate cuts in water consumption, the lake could vanish in just five years. Correspondent Lee Cowan talks with Sen. Mitt Romney, who co-sponsored a bill studying the lake's problems, and with experts who say aggressive action is needed.
