The idea of turning recycled plastic bottles into clothing is not new. During the past five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into clothing to deal with plastic pollution. But there"s a problem with this method. Research now shows that microfibers（微纤维）could be the biggest source of plastic in the sea.
Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years. He explains that every time synthetic（合成的）clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can"t collect these microfibers. So every time the water gets out of a washing machine, microfibers enter the sewer and finally end up in the sea.
In 2011, Browne wrote a paper stating that a single piece of synthetic clothing can produce more than 1,900 fibers per wash. Browne collected samples（样本）from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.
