But as artificial-reef initiatives grow to include more coastal regions and a wider【C1】______of aged infrastructure(基础设施), some scientists worry that the commercial interests of fishing, diving and trash【C2】______are driving efforts that should be environmental. 【C3】______that’s the case, they warn. 【C4】______reefs may ultimately give way to an underwater junkyard. "【C5】______it’s one of these things where people take a very【C6】______view—drop something in the water and a bunch of fish come and that’s wonderful, " says Bohnsack, a fisheries biologist.

" Research shows that artificial reefs only【C11】______fish populations when habitat is the limiting factor. In many cases. it isn’t.

The government is still cleaning up an ill-fated 1970s attempt at artificial reefing that employed more than 2 million tires【C16】______together with weak metal clips off the coast of southern Florida. The tires came【C17】______from one another during a rash of【C18】______storms. Since then, they have been【C19】______around the ocean floor, destroying natural reefs, polluting the water and occasionally washing【C20】______on shore.  [br] 【C13】
