Tibetan antelope

The Tibetan antelope, also known as "chiru," is one of the most beautiful mammals in the world. Its thick, woolly, cream-colored coat provides needed protection against the cold Tibetan winters. Unfortunately, people pay thousands of dollars for scarves made from these coats to keep warm, too. It's illegal to buy or sell anything made from Tibetan antelope fur.
