How humans impact this ecosystem

The vast muddy expanses of the abyssal plains occupy about 60 percent of the Earth's surface and are important in global carbon cycling. Based on long-term studies of two such areas, a new paper in the Proceedings of the National Academy of Sciences (PNAS) shows that animal communities on the abyssal sea .In this cold, dark environment, very little food is available. What food there is takes the form of bits of organic debris drifting down from the sunlit surface waters, thousands of meters above. During its long descent, this organic matter may be eaten, pooped out, and decomposed, drastically reducing its nutritive value. It is estimated that less than five percent of the organic matter produced at the surface reaches the abyssal plains.The sea floor is affected in a variety of ways by CLIMATE CHANGE.We also impact this ecosystem especially when ships dump garbage in our oceans or when they have an oil spill.
