KOLKATA AIR: A DEADLY NEIGHBOUR

摘要

Human civilisation is at stake - it is facing threats from the pollution of land, water and air. Of the three, air pollution has assumed an alarming proportion in India. According to WHO, 13 of the cities with the greatest level of airborne particulate matter (detrimental to health) in the world are from India. Approximately 1 Lakh people in India die prematurely because of air pollution. Delhi has the most polluted air in the world. Air in Delhi is estimated to surpass the accepted limit of pollution by four times and is twice more toxic than the air in Beijing, crowned until recently as the 'most polluted city in the world'. We, the human beings, are primarily responsible for this pollution, although natural phenomena like volcanic eruptions, forest fires and radioactive decay also contribute to it. Air pollution is undeniably a global concern.
