Sharks(鲨鱼) are not as dangerous to humans as humans are to sharks. Eventhough millions of people swim in the seas each year, fewer than fifty seriousshark attacks appear usually, and only ten of these are fatal (致命的). The reason for thislow accident rate is that most sharks are afraid of living things as large ashumans. Of the350 known kinds of sharks, only one — the great white shark — istotally unafraid of humans. At the same time, humans kill sharks in greaternumbers than in the past. Thousands are hunted and killed each year for food．Thousands more arekilled by the nets under the water, which are put off the beaches to protectswimmers in Australia and South Africa．Even the great whiteshark is reducing as humans hunt it for its teeth, which are sold tocollectors. Maybe it is time we began worrying less about protecting peoplefrom sharks and more about protecting sharks from people.
