Of the most devastating elements of this pollution is that plastics takes thousands of years to decay. ... As a result, fish and wildlife are becoming intoxicated. Consequently the toxins from the plastics have entered the food chain, threatening human health.
Long term usage and exposure of plastics and plastic products to high temperature can lead to leaching of toxic chemical constituents into food, drinks and water. Indiscriminate disposal of plastics on land and open air burning can lead to the release of toxic chemicals into the air causing public health hazards.
