They are confusing-and even killing-fish, whales and other marine animals. Although hearing is important to all

7、 animals, the special qualities of the undersea world emphasize the use of sound. Underwater sound allows marine animals to gather information and communicate at great distances and from all directions. Loud underwater noises can cause damage to their hearing. And nowadays its becoming too much for

8、marine wildlife. Evidence shows that whales will swim hundreds of miles, rapidly change their depth, and even beach themselves to get away from the sounds of sonar. You might think lower noises, typically caused by shipping or construction, do not pose a threat to marine animals. In fact, while they

9、 may not kill the animals directly, they can disturb their ability to locate food, find mates and avoid predators(掠食动物).Scientists looked at the effects of noise from small motorboats on coral-reef fish at the Great Barrier Reef in Australia. In the lab, the fish had been trained to recognize the sm

It turned out that the first group showed no fright reactions when exposed to the predator. However, the other group was scared. And un

Humans rely on the ocean for its natural resources and biodiversity. The ocean also plays an important role in regulating(调节)temperatures. As Cousteau said，For most
