that garbage patches where plastics accumulate, are to be found in even greater. This picture taken in Salinas del Rey beach (Caribbean coast of Colombia) is a good example of how litter can be harmful to the environment in several ways. With its powerful lobby, the plastics industry argues that jobs will disappear. Other terms used prior to 1984 include the following: man-made debris (Feder et all 1978 synthetic debris (Balazs 1979 plastic litter (Merrell 1980 floating plastic debris (Morris 1980 man-made objects (Shaughnessy 1980, Venrick et al 1973 and debris (Scordino and Fisher 1983). The Hebridean Whale and Dolphin Trust took various skin and blubber samples and removed the stomach for further study by the Scottish Agricultural College. In the birds gullets researchers found red plastic particles. Larges masses of ever-accumulating floating debris fields across the seas. The plastics are not quite ready for commercialization. While the potential toxicity of these tiny plastic constituents is still understudied for much of marine life, plastics are abundant in many forms. The photo-degradation process continues down to the molecular level, yet photo-degraded plastic remains a polymer. Were afraid at what were going to find in the South Gyre, but weve got to go there, said Tony Haymet.
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. It is a compelling global snapshot of marine debris collected on one day at thousands of sites all over the world. 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. The microbes that break down other substances do not recognize plastic as food. The National Oceanographic and Atmospheric Administration said that plastic debris kills an estimated 100,000 marine mammals annually, millions of birds and fishes. Over time plastic breaks down in small particles of just a few millimeter.
