Animals of various species inhabiting a lake can be destroyed by sewage pollution?

Dr Saido’s study was the first one to look at what actually happens over the years to these tons of plastic waste floating in the world’s oceans. The study presents an alarming fact: these tons of plastic waste reputed to be virtually indestructible, do decompose with surprising speed, at much lower temperature than previously thought possible, and release toxic substances into the seawater, namely bisphenol A (BPA) and PS oligomer. These chemicals are considered toxic and can be metabolized subsequent to ingestion, leading Dr Saido to state “…plastics in the ocean will certainly give rise to new sources of global contaminations that will persist long into the future”.
