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

　　In "Sharkwater," Rob Stewart uncovers the illegal shark fin trade in Costa Rica. In Asian countries, the high demand for shark fins for cooking has led to an illegal trade worth millions of dollars. The mass killing of sharks continues because very few countries have rules to protect the creatures.

　　"Sharkwater" shows beautiful images of sharks in nature. For example, you can see hundreds of female hammerhead sharks gathering to find mates. You can see Mister Stewart holding a playful shark underwater. But the movie also shows the terrible reality of shark fishing. It shows bloody images of fisherman cutting the fins off dead sharks then throwing them back in the water.

　　The movie says that the world's shark population has dropped by an estimated ninety percent. And, it explains how life on land depends on life in the ocean. So, by saving sharks we are also helping to save people.
