No place on Earth is free from pollution : Research

Environmental pollution is caused by more than 3.5 lakh chemicals currently in use

Stockholm (Sweden) – The Pacific Ocean has been polluted to a depth of 8,000 meters. During the 20th century, 60% of man-made pollution was deposited in the deep ocean. According to Stockholm University’s Department of Natural Sciences, ‘No place on Earth is free from pollution’. The research has been published in the April issue of the scientific journal ‘The Nature’.

Researchers say that more than 3.5 lakh chemicals currently in use worldwide are polluting the environment. Pollution at the bottom of the Pacific Ocean is dangerous to humans.

Human-made pollutants have recently been discovered in the deepest and most remote places on Earth. The Atacama Trench is 8,000 meters deep in the Pacific Ocean. The researcher said, pollutants called ‘polychlorinated biphenyls (PCBs)’ were found in such remote places.

‘Polychlorinated biphenyls’ were used excessively in the last century

From the 1930s to the 1970s, PCBs were produced on a large scale in most of the Northern Hemisphere. It was used for electrical appliances, paints, and many other items. In the 1960s, it was realised that this was harming marine life. This led to a global ban on their use in the mid-1970s.


Editorial viewpoint

Does science benefit from producing chemicals that harm nature ? In light of this, the question arises as to whether science is a blessing or a curse for mankind !
