in covid-19 lock down
As the corona virus disease 2019 pandemic impacts millions across the world and brings economies to a grinding halt, there is lot of talks about how emissions from fossil fuel combustion have dropped radically in many countries. Recently air pollution levels have started to drop dramatically as second most populated nation endures the third week of down amidst coronavirus fears.While the complete lockdown of India's economy was designed to stop spread of covid-19, it's having and ancillary healthy benefit of clearing the air that millions of people were chocking on.As vehicles day of the road, construction is put on hold and factories stop production the level of microscopic particlulate matter.It's true that pollution levels are going down and will continue to be lower as a result of lockdown. Recent heavy rains in the north and West of country have also helped the country's pollution levels, rain is a very effective aerosol removal process from the atmosphere and can bring lower particulate matter (PM) values. Since the March 25 lockdown that forced 1.3 billion Indians to stay home, air quality across major polluted cities has dropped to satisfactory levels.The effect of lockdown has been dramatic.The air quality is likely to slip into good category soon. Water bodies have also been clearing and the rivers Yamuna and Ganga have seen significant enforcement of a nationwide lockdown. Even before coronavirus air pollution killed 7 million an year, shall today's cleaner inspire us to do better ! however, it's important to remember that this is a temporary reprieve that will return if industry and vehicular traffic return once the lockdown is over. Efforts to control the corona virus pandemic have reduced economic activity and led to localised improvements in the air quality.But it is too early to assess the implications for concentration of greenhouse gases which is responsible for long-term climatic change.
