TTest (1184411) writes "Kinda like in Fern Gully... only real. Scientists at the University of Washington are reporting the creation of fast-growing, pollutant-eating poplar trees. According to a NIH press release, the trees rapidly absorb and break down cancer-causing hydrocarbons from the air and soil around them. The original research publication also mentions that the trees may be cheaper than conventional waste clean-up techniques, prevent erosion, capture carbon dioxide from the atmosphere, and can be harvested to make biofuel or paper."
