Why is the world's biggest landfill in the Pacific Ocean? In the broad expanse of the northern Pacific Ocean, there exists the North Pacific Subtropical Gyre, a slowly moving, clockwise spiral of currents created by a high-pressure system of air currents.

Garbage patches are large areas of the ocean where litter, fishing gear, and other debris - known as marine debris - collects. They are formed by rotating ocean currents called “gyres.” You can think of them as big whirlpools that pull objects in. Great Pacific garbage patch. Great Pacific Garbage Patch now three times the size of France. According to a three-year study published in Scientific Reports Friday, the mass known as the Great Pacific Garbage Patch is about 1.6 million square kilometers in size -- up to 16 times bigger than previous estimates.
That makes it more than double the size of Texas. Ghost nets, or discarded fishing nets, make up almost half the 80,000 metric tons of garbage floating at sea, and researchers believe that around 20% of the total volume of trash is debris from the 2011 Japanese tsunami. The study -- conducted by an international team of scientists with The Ocean Cleanup Foundation, six universities and an aerial sensor company -- utilized two aircraft surveys and 30 vessels to cross the debris field. Along with nets to survey and collect trash, researchers used two six-meter-wide devices to measure medium to large-sized objects.
Massive South Pacific Ocean garbage patch ‘a dead place’ A marine conservationist who has just returned from an expedition to survey a massive 'garbage patch' in the South Pacific ocean says it's completely devoid of marine life.

Unfortunately, it is being threatened by pollution from people on land and from natural causes. Marine life is dying, and as a result the whole oceanic ecosystem is threatened simply by various sources of pollution. If we are to preserve ocean and its natural beauty, drastic measures have to be taken to combat this pollution and keep what we hold most dear. Before, it was assumed that because the ocean was so big, vast and deep, that the effects of dumping trash and litter into the sea would only have minimal consequences. But as we have seen, this has proven to not be the case. 22 Facts About Plastic Pollution (And 10 Things We Can Do About It) - EcoWatch.

New research suggests that 90 percent of that waste gets into the oceans through 10 major river systems. “It seems that larger rivers preferentially transport plastic and these are rivers with a large population. You could reduce river plastic loads tremendously by focusing on these 10 rivers,” lead researcher Christian Schmidt of Germany’s Helmholtz Center for Environmental Research, told VOA.
