Yaks are very important for the survival of the people in the high mountains. They are used as pack, draft, and saddle animals in the plateaus and mountains. The hides of yaks provide leather, and the tails are valued as fly whisks in India. Domesticated yaks are also kept for milk and beef. The hair from the long fringes of the flanks is used in making cords and ropes. The dried dung of the yak is the only obtainable fuel on the treeless Tibetan plateaus. Other pack animals in the mountains are mules and donkeys. Small horse races are used mostly for riding. The mountain goats supply not only meet and milk, but the expensive cashmere hair fibre too. The cashmere goat has a protective outer coat of coarse fibre that is 4 to 20 cm in length. The downy undercoat is made up of the fine, soft fibre commonly called cashmere, which ranges from 2.5 to 9 cm long. Most of this down fibre is plucked or combed out by hand during the molting season. The annual yield per animal ranges from a few grams to about 0.5 kilogram. Even more finer and more expensive as cashmere fibre is the hair of the highly endangered Tibetan antelope. Unfortunately they are not domesticated and to get the fibre the seldom animals have to be killed. There are still some few nomadic tribes in Tibet, Ladakh and in West-Nepal, which live with their animal herds at the altitudes between 4000 and 5000m. In the icy-cold winters the mothers pack their children warm dung under the furs, to prevent freezing of hands and feet. Because there is no medical care each forth women dies by birth, and from two babies survives only one. That's the reason, why the parents give their children the name not until they are three years old.
