How COVID-18 has affected Environment? 

Due to COVID-19, the emission of greenhouse gases have fallen across the world because the factories, transportation and vehicles are stopped running and due to this, the CO2 is decreases averagely 5% across the world and carbon monoxide is reduced 50% compared to last year.

In last three months, the world has been transformed. Wuhan city is the origin of coronavirus and from there it is spreader across the world and almost in all the countries, lockdown is announced and crores of families are locked in their house because the factories except essential needs are closed. The electricity to be consumed in that factories and vehicles is not consumed so the government and other electrical energy producer are required to generate less electrical energy compared to previous years and we all know that major electricity is generated by the coal energy and as the demand of electrical energy is reduced, fewer coals are being used compared to previous years so the emission of flue gases by that coals is reduced much and the environment is less polluted in the year2020.

The fact is that economy is inversely proportional to the environment. as the factories are closed, transportation vehicles are required to use very less and normal people cannot use their vehicles, the production and distribution of goods(except essential goods) is stopped so that the economy of the country is directly affected and as the economy falls the pollution level of the country decreases.

Most of the countries have stopped the flights, due to this the pollution decreases much because there were always rush in flights and day by day more and more flights were flying in the sky. The flights require more fuel than other commercial vehicles. 

The trains are stopped except the coal carrying trains. Coal carrying for electricity generation and in essential needs. So as the passenger trains are closed, the coal and diesel used to run trains are left out. As the train is electric or diesel in both cases fossil fuel is being used. If the train is electric, the electricity on which it runs is majorly generated by the coal and as it is diesel type, it consumes diesel and in both cases the pollution occurs. The Indian railway consumes 2.6 billion liters of diesel annually, it means the consumption of diesel in Indian railways is decreased 660 million liters till now in the year 2020. In the year 2019, 574 million tons of coal was used to generate electricity for electrified routes and for houses and factories. That coal usage is decreased much in the year 2020. So the pollution occurring by Indian railways is decreased much. Due to this less use of fuel and coal, we can say that pollution is decreased much due to covid-19.
