We asked youth radio groups from Portland, Maine, to Seattle, Washington, to pick a product or a pastime and size up its green credentials. What they learned surprised us - like this piece from Zoe Sheinkopf from public radio station KUOW’s weekday high radio training program in Seattle, Washington. She followed the leftovers from a local university cafeteria to a distant compost heap to find out what becomes of all that waste, and to weigh the economic and environmental advantages of composting over just chucking garbage in the trash.
