VOA慢速英语 Unemployment Leads to Increased Volunteerism in the United States

　　About seven years ago, Rob Stewart was working in the Galapagos Islands photographing sharks. There, he discovered that the illegal practice of long-line fishing was taking place in a protected sea area. This method of fishing kills huge numbers of sharks and other sea animals. So, Mister Stewart decided to make a movie to increase public awareness about sharks. He spent four years filming in fifteen different countries.

　　ROB STEWART: "You're underwater and you see the thing that you were taught your whole life to fear. And it doesn't want to hurt you. And it's the most beautiful thing you've ever seen. And your whole world changes."

　　Sharks have existed for hundreds of millions of years. They developed more than a hundred million years before the dinosaurs. Sharks play an important role in the food chain. So when their numbers fall, the entire ecosystem of the ocean is put at risk.

　　Rob Stewart explains that people fear sharks because of media stories and movies about shark attacks. But he says in fact, sharks are very shy creatures that do not like to attack humans. He says that elephant attacks kill far more people a year than shark attacks. But few people are afraid of elephants as they are of sharks.
