Sharks have a lot to fear from humans.
Compared to the six to seven people killed each year by sharks, over 100 million sharks die at the hands of humans every year and many populations face extinction. Sharks are killed for many reasons, including fear , food and sport . The majority die simply because of human greed. Many shark products are sold, including the flesh, the skin, the teeth, jaws, liver oil, cartilage and the fins. The skin is used for high quality leather, the teeth and jaws for ornaments or decorations, the oil from the liver is used in cosmetics, medicines, vitamins and skin care products and the cartilage is sometimes used for false cancer cures.
