Ocean Array Could Clean Up Tons Of Plastic
Millions of tons of tiny bits of plastic float in giant patches â€” or gyres â€” in oceans around the world. There are five large patches of plastic. One of them, the North Pacific Gyre, is roughly twice the size of the United States. All of them are a problem. These bits of plastic look like food to fish and birds and once consumed, end up killing these animals. But the plastic bits also contain chemicals, such as DDTs and PCBs, that once consumed by small sea creatures then enter the food chain to be consumed eventually by people. And because plastic doesnâ€™t break down and dissolve, these gyres are going to be around for hundreds, if not thousands of years, even if we stopped polluting tomorrow.
