In the Pacific Ocean, between Hawaii and California, at least 79,000 metric tons of plastic has coalesced to create the Great Pacific Garbage Patch. The patch, kept together by ocean currents and spanning an area of roughly 1.6 million square kilometers — about twice the size of Texas — is one of the most incriminating examples of human pollution on the planet. It’s also a huge hazard for marine life, killing up to 1 million seabirds and 100,000 marine mammals each year via ingestion of plastic or entanglement in plastic pieces.
