Positive effects on environment due to Covid-19:-
1. Reduction of air contamination and green-house gases- As businesses, transportation, and organizations have shut down, it has brought an abrupt drop of ozone-depleting substances discharges. Contrasted and this season of a year ago, levels of air contamination in New York has decreased by almost half due to measures taken to control the infection. It was assessed that almost half the decrease in nitrogen dioxide (N2O) and carbon monoxide (CO) happened because of the closure of hefty businesses in China. Likewise, the outflow of NO₂ is one of the critical markers of worldwide monetary exercises, which shows an indication of a decrease in numerous nations, for instance, the US, Canada, China, India, Italy, Brazil, and so forth because of the complete lockdown situations. Typically, NO2 is radiated from the consumption of non-renewable energy sources, 80% of which comes from engine vehicle fumes. It is accounted for that NO2 causes corrosive downpour with the collaboration of O2 and H2O, and a few respiratory sicknesses endured by people. The European Environmental Agency (EEA) anticipated that, due to the COVID-19 lockdown, NO2 discharge dropped from 30-60% in numerous European urban communities including Barcelona, Madrid, Milan, Rome and Paris. In the US NO2 declined 25.5% during the COVID-19 period contrasted with earlier years. It was likewise expressed that, the degrees of NO2 and diminished by practically 70% in Delhi, the capital of India.
2. Reduction of water contamination- Water contamination is a typical marvel of a non-industrial nation like India, and Bangladesh, where home-grown and mechanical squanders are unloaded into streams without treatment. During the lockdown time frame, the major modern wellsprings of contamination have contracted or totally halted, which assisted with diminishing the contamination load. For example, the waterway Ganga and Yamuna have arrived at a huge degree of virtue because of the shortfall of mechanical contamination on the times of lockdown in India. It is discovered that, among the 36 constant observing stations of stream Ganga, water from 27 stations met as far as possible. This improvement of water quality at Haridwar and Rishikesh was credited to the abrupt drop of the quantity of guests and 500% decrease of sewage and mechanical effluents.
