By finishing up talking about the environmental effects of Deepwater Horizon oil spill, the destruction of coral reefs was another crucial part. The oil not only floated on the surface of the ocean, but also precipitated down to the deep-sea area. The coral reefs, the important deep ocean habitats, were covered by the sediment of oil, and they were seriously damaged. By analyzing the flocculent precipitate covered on the corals, it was proofed that the sediment was consistent with the petroleum hydrocarbon compounds in the oil. The scientists then concluded that the large area damage of coral communities, which expanded down to the depth of 1,370 meters, was the direct result from the oil spill (White et al., 20306). The injured corals most
