|Plastic waste SC6486|
“Plastic first became widespread in the mid-20th century. Since then, about six billion tons have been manufactured. Much of that has ended up as trash, and nobody knows what will become of it.Now researchers have discovered an unexpected way that some plastic waste is persisting: as a new type of stone.The substance, called plastiglomerate, is a fusion of natural and manufactured materials. Melted plastic binds together sand, shells, pebbles, basalt, coral and wood, or seeps into the cavities of larger rocks to form a rock-plastic hybrid. The resulting materials, researchers report in the journal GSA Today, will probably be long-lived and could even become permanent markers in the planet’s geologic record.” – Rachel Nuwer, June 9, 2014, The New York Times, http://www.nytimes.com/2014/06/10/science/earth/future-fossils-plastic-stone.html?ref=scienceTo continue reading click here.
