EARTH: Tracking plastic in the oceans

Humans produce over 260 million tons of plastic each year. Almost a third of that plastic goes into disposable, one-time-use items, and only about 1% of it is recycled globally. Where does the rest of the plastic go? How does it interact with our environment? And how will it impact us in the future? In this month's issue of EARTH Magazine, follow the fate of many plastics as they make their way from our homes to our planet's oceans.

While no one knows exactly how much plastic is in the ocean, studies over the past few decades have suggested that millions of square kilometers of ocean surface may be covered with floating garbage "patches." Today, at least five such patches are known to exist. The largest, the Great Pacific Garbage Patch, floats miles off the coast of Hawaii and is estimated to be roughly the size of Texas. Where did this refuse come from? How is it affecting our oceans? And will we ever be able to remove the trash? Find out at http://www.earthmagazine.org/article/tracking-plastic-oceans.
