Many people like to go diving (潜水) when they are on holiday. Jenney, a 14-year-old girl, is getting ready to have a special dive with sharks in the sea of Florida. It's really expensive for her to do it. Sounds crazy?
Shark diving is big business in some places and that's raising a question about how close people should get to them. Some brave divers think it is no problem for them to get close to sharks. Divers in Florida, for example, often have fun with lemon sharks, which have attacked people a few times before. On the other side, many people are against shark diving. They think no one should go diving with sharks. And it is foolish to feed sharks while diving and bring them close to busy beaches.
Bob Dimond has been a diver for 30 years. He's worried that sharks may lose their fear of humans." The reason why people feed sharks is to attract them, but people don't want to be sharks' food. However, when sharks learn to connect humans with food, they approach to see if they can find something to eat, Bob says." That's reason enough to stay away from sharks."
Bob has created the Marine (海洋的) Safety Group. He and his friends believe if people feed a wild animal, they will increase the chance to be attacked. Therefore, their goal is to stop all shark feeding. In fact, shark feeding has never been directly associated with an attack on a human. When a shark strikes, it is usually" hit and run". It bites and then quickly releases the person and disappears.
Obviously, sharks make shark diving so attractive. For divers such as Jenney, diving with sharks is a once-in-a-life experience. Jenney says," I actually had a chance to lie down on the bottom of the ocean and the sharks were right in front of me. And I could see their mouths and their eyes and feed them. I used to know only a little about sharks, but now I want more teenagers to join me."
