The World’s Largest Dump

In the middle of the Pacific Ocean, between San Francisco and Hawaii, is an area roughly 4 times the size of California that contains approximately 1.8 trillion pieces of trash weighing 80,000 metric tons.

It covers 618,000 square miles and is growing.  The trash collects in the area because of a meteorological phenomenon called the North Pacific Gyre, which is a system of circulating currents in the ocean. From time to time, the ocean currents can cause the area to spit out some of the debris, much of which accumulates on the beaches in the Hawaiian Islands.
