Student interest fuels green campus innovations

On Earth Day in 1970, months before the Environmental Protection Agency existed, a group of eco-minded students at the University of Colorado at Boulder started something big -- and green. More than 40 years later, CU's Environmental Center has grown to employ more than 100 students, operate a recycling program so large it actually turns a profit, and lead U.S. schools in green campus innovation. It has learned, as other colleges are realizing, that going green goes beyond environmental stewardship -- it's also good business.
