Plastic pollution set foot in fossil record, says study


A new study has found that presence of plastic deposits exponentially since 1945 which has lead to new discovery. This development of plastic presence in making fossil record was found by researchers in Scripps Institution of Oceanography at the University of California San Diego. They have found that plastic dating back in 1834 have increased exponentially since the end of World War ||, which is doubling every 15 years.


The researchers found that most of the plastic were fibers from synthetic fabrics used in clothes which were flowing into the ocean through waste water. The researchers have clear picture of plastics which was found in sedimentary record when they were doing research in Oceanography.


The researchers found that increase of plastics in the sediments were gradually a rise in the plastic production worldwide. The traces of plastics were found in the fossil record through core from 1945 but most of the plastics were invented in 1920’s, it was commercially used in World War ||. So, it was mostly used from 1945 and it started increasing rapidly by 2010 and deposits of plastic were ten times more after World War ||. After the War there is a rise and increase usage of plastics particles including fragments of plastics, materials made from plastics which is addition to fibers.


Plastic pollution has also a major impact on marine species. When animals eat these plastic pieces, the toxins are absorbed into their body and passed up the food chain. As plastics break apart in the ocean, they also release potentially toxic chemicals such as bisphenol A (BPA), which can then enter the food web. So, it is a clear warning for human mankind to reduce the usage of Plastic! Let’s try to avoid plastic to have a sustainable life.
