Christian Colleges' Green Revolution
From the cafeteria to the classroom, students are learning to be environmentally conscious.

Flush twice. It's required at Calvin College's Vincent and Helen Bunker Interpretive Center's restrooms; once before, once after. The flushed water, which is the consistency of a bubble bath, washes waste to an underground room. There, preserve manager Cheryl Hoogewind and I climb up on a metal receptacle and look into a huge bin of waste that smells pleasantly of wood chips. This compost will eventually be spread as fertilizer on the college grounds.

Above us in the 5,000-square-foot building, a student-designed solar photovoltaic system generates electricity from sunlight; meanwhile, gray water from drinking fountains and sinks nourishes plants lining the classroom windowsills. It's all part of the Bunker Center's environmental sustainability.
the rest
