Covid 19 has slowed down many environmental factors that led to its destruction. There has been less pollution overall. The temperature is stabilizing. Aminals are taking their place back. Many rare animals have been roaming in many wildlife videos. River and lakes have never been cleaner as in the case of Italy. This all happened due to worldwide lockdowns as a result of which people are staying more at home. So there is no traffic on the road , as a result, less fuel used, less carbon monoxide emitted.
In China, the emission pollutants fell 25% as compared to the same period of the previous year. China is the biggest producer of pollutants. Its largest coal power plant is producing 50% less pollution.

This clearly shows that Covid 19 has bought many significant changes that would otherwise be nearly impossible to occur. This shows the decrease in pollution around Europe.
