Widespread Covid-19 has created a terror worldwide, where the world has come to a pause, no human interaction, no outings, no occasion, no transports, etc, and a continuous series of lockdowns. Coronavirus is a type of zoonotic disease. A disease that is infectious and is transmitted from humans to animals or vice-versa. Coronavirus was found in bats which were originated from Wuhan in 2019 then to World. After two decades this is the third time when the coronavirus has been affected again. In 2003 and 2012 severe acute respiratory syndrome and middle east respiratory syndrome coronavirus respectively, was detected. We are in the second wave of covid-19 with well aware of symptoms, vaccinated, and following the precautionary measures. Covid-19 is a contagious disease spreading like a holocaust, people dying, families collapsing, economy dying, etc. But every cent has two faces, the good one and the bad one.
During the starting of the pandemic, when all the industrial activities, transportation, and tourism were closed it seemed nature choose to open up to us. The pollution level decreased dramatically. the quality of air became better, the sky found its sparrows, the lost fishes started showing up, and the flower that was dying bloomed at its happiest.
The study of air quality during the covid-19 pandemic will leave you stunned. Aerosols are the small particles in the air or small particle in the droplet that are suspended in the atmosphere which has an adverse effect on health. A satellite image report by NASA(31 march,2016 to 5 April 2020) shows the Aerosol Optical Depth(AOD) measured in 2020 is relatively very low or very little compared to another year, which is the impact of lockdown.
Also, European Space Agency said in a report, the nitrogen dioxide level in the atmosphere has reduced 40% – 50% relatively (January to April 2020). Nitrogen dioxide produces due to means of transportation, power plant, and industries. The particulate matter (PM2.5 and PM10) is also an indicator of air quality which has reduced with the above air quality indicator which as well a positive impact on lockdown.
Not only the air but the river which we almost forgot the colour of, finally could be seen blue. A report by CPCB said the Ganges are now suitable for irrigation, fisheries, and wildlife. As the Ganga is well known for its self-cleaning property, due to the industrial and holy waste it was partially losing its uniqueness. Now the Ganga is gaining back its self-cleansing property by 40% – 50% during the pandemic, due to the closure of industries and holy places. Where in the second place Yamuna is seen clearer and more bluish after a decade. Because of the toxins released from the detergents, industries, and sewages, the toxic foams were formed earlier.
Reports of Cauvery and its tributaries are seen unburdened by the wastes, following by Punjab’s Sutlej.
Hereby, the pandemic has taught the importance of mother earth. Today we are witnessing the heart-wrenching stories of common people, losing our doctors, their sacrifices, common people coming together to lend a helping hand, hoping for a ray of victory. But the mother earth after decades revived herself, the plants breathing, the fishes swimming, the wildlife living again and birds flying above in the sky. Where there is sadness on one side and happiness on another side. Come let us save the world together with love, care, and peace.
