　　(2016·甘肃第一次诊断)You may not know it but on our biosphere(生物圈)－Earth－there is also a relatively unknown world hiding in plain sight.It is made up of microbes(微生物)that live on floating pieces of plastic floating on the ocean.

　　This “Plastisphere” of microbial organism living on ocean plastic was first discovered last year and it is now getting studied.When researchers first examined the Plastisphere，they found at least 1,000 different types of microbes living on the tiny plastic islands，and worried that they might cause a risk to larger animals and humans.They also found that the Plastisphere's microbes included bacteria known to cause diseases in animals and humans.Since then，researchers have been trying to figure out why these potentially dangerous bacteria live on the Plastisphere，how they got there and how they are affecting the surrounding ocean.
