sciencehabit (1205606) writes "Plastic may be with us a lot longer than we thought. In addition to clogging up landfills and becoming trapped in Arctic ice, some of it is turning into stone. Scientists say a new type of rock cobbled together from plastic, volcanic rock, beach sand, seashells, and corals has begun forming on the shores of Hawaii. The new material--which the researchers are calling a "plastiglomerate"--may be becoming so pervasive that it actually becomes part of the geologic record."
