Coronavirus, also named as COVID-19, had first evolved in Wuhan, China, in December 2019. But now it has gripped the whole world. This virus has affected more than a million people and thousands have lost their lives already.
Due to global pandemic COVID-19 , many countries around the world had to declare lockdown. All the ongoing works in factories and industries and the other fields have stopped except the most important ones.
Most powerful countries in the world like the USA, China, etc could not control it. It’s about to four months since the virus evolved but no scientist and researchers are able to discover it’s vaccine yet. All the working fields have been closed which has led to the regression of economic condition.
With no doubt, this lockdown has caused the economy of the world to relapse. Besides all these negative impacts there is also a piece of silver good news. It’s about decreasing pollution.
Air pollution is a great threat to the environment. The pollution had actually destroyed the beauty of nature. The lockdown has actually helped to protect the environment. The human being is directly connected to the environment. So, it’s not only protecting the environment but also the human being.
On early March 2020, the European Space Agency (ESA) satellite showed the data. According to the data, there is a significant reduction in emission of carbon, nitrogen dioxide and other hazardous gases and particles. As compared to the data of 2019, there is an astonishing fall in air pollution in different parts of the world.
Effects of coronavirus on air:
As per the latest report of WHO, 4.2 million people die as a result of air pollution every year. But, the lockdown has unexpectedly affected the air quality index to a large extent. This decreased air pollution has possibly saved many lives.
According to G-FEED (Global Food, Environment and Economic Dynamics), reduction in air pollution in China has probably saved the lives of 4,000 children under 5 and 73,000 adults over 70. This data shows that the number of people survived due to the reduction in air pollution is significantly more than the current number of deaths from the virus itself.
Nearly after 7.5 decades, scientists have observed such a clean earth’s atmosphere. As per their indication, Earth had such an atmosphere before the Second World War. This year GCO (Global Carbon Project) has expected in the reduction of carbon to 5%.
The ozone layer is responsible for absorbing the sun’s harmful ultraviolet radiation. Since many years it had declined so much that a 1987 agreement known as the Montreal Protocol put a stop to the use of ozone-depleting substances (ODSs) around the world. But according to a new study published in the journal Nature shows that the protocol has been effective. The ozone layer has begun healing. The evidence for this recovery is the change in the jet stream. The shrinking in the ozone hole is a good sign for the improvement of the environment.
Effects of coronavirus on water:
There is a positive impact on water too. The government has closed their countries for visitors and said the residence to stay at home to slow the spread of COVID-19. There is no boat running in the rivers and other resources. Due to this reason the usual murky water has turned crystal clear. The normally polluted water of canals, rivers and other water resources are much clearer now. The environment has much relief now. This is because of Slowing down in the release of waste into the air and water due to closedown of large and small scale industries and factories.
Since a very long time we are listening that the world would suffer a lot if it continues to produce harmful gases. But, at this moment it’s a little bit different. There is a sharp fall in air pollution which is the positive impact caused by COVID-19. Yes, this will last only for a short period; the period as long as the lockdown continues or as long as this coronavirus does not fade away. This does not mean that the virus is useful or effective in any sense. Rather we can learn something from this short-term positive impact.
Scientists are afraid that this positive impact would not last long. But if we try, we can make it to a longer period. We can use the most important principle to minimize the emission which is 3R principle; Reduce, Reuse and Recycle. This principle can help a lot if we really want to try to control the pollution.
