There are two main reasons for the destruction（破壞） —the 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， the loss caused by the latter can be reduced． Bottom operation involves dropping s 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 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 case for Coralbots—the robots that can constantly seek out broken branches． A team of ?coralbots?， each working to simple rules will piece together? damaged bits of coral, allowing them to regrow(重生 ). They are programmed to be able to tell the differences between other things and the coral． The robots work together in groups， similar to bees． If one coralbot is damaged then the others will still be able to plete the task． Dr LeaAnne Henry said： “The project of using coralbots offers us the possibility to restore(修復(fù) )the function of reefs． It is in the final stage of testing． Once ready, the researchers hope to build hundreds of them and use them effectively in the waters off Scotland and then hopefully in the oceans across the world． ” 28.
