Fossil fuel-derived synthetic fibers, which are nonrenewable and nonbiodegradable, currently comprise approximately 60% of materials used by the fashion, automotive, and home goods industries and are projected to comprise approximately 70% of materials by 2030. Synthetic materials contain microplastics, which accumulate and persist in ecosystems for hundreds of years, as well as toxins that poison ecosystems, harm animals, and fuel climate change.
