Hand washing fabrics reduces microplastic release compared with machine washing

From tiny plankton to massive whales, microplastics have been found throughout the ocean food chain. One major source of this pollution are fibers shed while laundering synthetic fabrics. Although many studies show microfibers are released during machine washing, it's been less clear how hand washing contributes. Now, researchers report that hand washing can drastically cut the amount of fibers shed compared with using a machine.
