Plastic may release the heat-trapping, climate-warming gases as soon as it’s exposed to light, new research from the University of Hawaii at Manoa has found. Light not only breaks down plastic, but also releases methane and ethylene — two of the most problematic greenhouse gases. Though the gases from degrading plastic…
