Studies have found that fur has many environmental benefits. Real fur is a natural, renewable resource. Farmed mink are fed with leftovers from abattoirs, fish plants and other food production by-products – they “recycle” wastes that would otherwise go to landfills. In addition to fur, farmed mink provide fine oils for skin care and waterproofing leather, organic fertilisers, bio-fuels and other products. Biofuels made from farmed mink are a second-generation biofuels, which are a lot better for the environment than the first generation biofuels. Additionally, carcasses from farmed mink are also used for heating purposes and in the production of cement.
