Sharks can be used in a variety of ways; the fins are used to make shark's fin soup, the skin is a kind of leather sometimes used for boots, wallets, etc.; an extract of shark's liver is used medically in Preparation H (a hemorrhoid medication). Aside from such direct uses, many people admire sharks for their efficiency and grace as predators. They are part of the great tapestry of life. Just don't let them bite you.
