ABOUT 6% OF THE WORLDWIDE OIL CONSUMPTION ARE USED FOR PLASTIC PRODUCTION. RECYCLED PLASTIC PRODUCES 3.5 kg CO2 COMPARED TO 6kg FOR NEW PLASTICS/kg. CURRENT WORLDWIDE PRODUCTION OF PLASTICS IS 35 kg per person INCREASING AT 3% PER ANUM. DURABILITY (SLOW PHOTO DEGREDATION) PERFECT MATERIAL FOR TOXIC ABSORBTION 40% OF PRODUCED PLASTIC IS DISPOSED WITHIN A YEAR INCREASING AVAILABILITY OF SINGLE USE PLASTICS Pusch, Thema Umwelt, 1/2009,p.3 OVERVIEW

STATEMENT OF PROBLEM DESPITE MARPOL ANNEX (V) INTERNATIONAL TREATY THAT PROHIBHITS THE DUMBING OF PLASTICS AT SEA, PLASTICS IN THE OCEAN IS INCREASING AT ALARMING RATE.

SOURCES OF MARINE PLASTICS

MUCH OF PLASTICS CONTAINS CHEMICALS THAT ARE HARMFUL TO MARINE ANIMALS. IMPACT ON MARINE ORGANISMS (GHOST FISHING, INGESTION , ENTANGLEMENT ) SOME PLASTICS DISTRACT ENDOCRINE SYSTEM IN HUMANS AND MARINE ANIMALS. ECOSYSTEM CHANGES ECONOMIC LOST IMPACTS
