摘　　要：Deep sea plastic biotas are formed by floating plastics that sank after biofouling.Plastics with nutrition and high biodiversity attract deep sea creatures and act as stepping-stone for biological striding.Plastics are cheap,light,water proof,sturdy and durable,with high insulativity.It is easy to shape and resistant to chemical corrosion.Therefore,plastics are widely used in the modern society,representing a major progress in human civilization.Global production of plastics has increased considerably over the last few decades from 1.7 million metric tons per year in the 1950s to 370 million metric tons per year in 2019[1].As a result,plastic wastes also increase quickly,e.g.,by~10%every year in the last decades.Around 6.3 billion metric tons of plastic wastes were generated between 1950 and 2015[2].Given that its degradation takes hundreds of years,plastic is even proposed as the No.1 environmental challenge.More than tens of thousands metric tons of plastics are dumped into the ocean every year[3].Fishing thread,microplastics and other plastics are indeed an increasing threat to ocean lives:ingestions and entanglements by the marine life[4].Nevertheless,the impact of such large amount of plastic garbage on ocean environment remains to be fully explored.
