Flexi Says: Microplastic pollution has become a big environmental problem. Microplastics are tiny pieces of plastic that are released into the environment as plastic products wear out and break down. Recycling plastics is one way to help prevent plastic waste from polluting the environment. However, some of the products made with recycled plastics can also cause problems. Clothes, soft furniture, and carpet made with plastic fibers can shed microplastics into the environment during normal wear and washing. Natural fibers are a better choice for these types of products.
