12、 of people. However, like many other species, this amazing ecosystem(生态系统)is in danger of dying out!There are two main reasons for the destructionthe rising carbon dioxide levels caused by global warming as well as human influences like bottom operation. While not much can be done about the former,
13、the loss caused by the latter can be reduced.Bottom operation involves dropping nets to the ocean bed and then dragging them up when filled with fish. This action damaged the ocean floor, causing the coral branches to separate from the reefs. While that is very discouraging, the good news is that if
14、 these branches are found quickly, they can be saved. At present, that work is being performed by volunteer divers. But the method has only limited success because they cannot stay long underwater, nor reach depths of over 200 meters where some of the deepsea coral grows.However, this is not the cas
15、e for Coralbotsthe robots that can constantly seek out broken branches. A team of coralbots， each individually working to simple rules will piece together damaged bits of coral, allowing them to regrow. They are programmed to be able to distinguish between other things and the coral. The robots work
16、 together in groups, similar to bees. If one coralbot is damaged then the others will still be able to complete the task.Dr LeaAnne Henry said: “The project of using coralbots offers us the possibility to restore(修复) the function of reefs. It is in the final stage of testing. Once ready, the researchers hope t
