Natural fur is a sustainable fashion material which can be absorbed back into nature's own cycle through biodegradation. A renewable resource with outstanding thermal qualities, natural fur also have much less impact on landfills and oceans than synthetic alternatives, which are made from plastics. Synthetic textiles such as polyester still make up the lion's share of the global textile market, and while the production of plastics is a major contributor to greenhouse gasses, the plastic pollution itself has become a major threat to the ecosystem.
