<br/>World plastic production was less than 2 million metric tons in 1950, but the cumulative amount of plastics produced from 1950 to 2015 is presently computed as 5.5 × 10 <sup>7 </sup>metric tons.  Due to human carelessness or accidents, land based waste or littering, plastic materials make their way into rivers throughout the world and ultimately into all the oceans of the world. Since 1950, waste/litter PS/plastics are progressively polluting oceans worldwide. This study was conducted to determine the fate of PS subsequent to its discharge into the ocean. The results clearly indicate PS to undergo decomposition with exposure to heat, light and waves in oceans with consequent generation of plastic monomers and oligomers. SO causing world wide ocean pollution has increased by 30,000 times as much in the past 60 years. The basic structural units of plastic pose significantly high risks to marine organism life, ecosystems and certainly, human health as well. The authors thus feel quite justified in the conviction that careful attention must be directed to the findings of this research as well as those of the plastics industry and other scientists as well.<br/>
