How Lockdown has Impacted Environment?

The Environment Day celebrated this year will be different from previous years. Due to the lockdown this year, a significant amount of pollution has been reduced. Till last year, where we were more concerned about environment, this year our worries are a little less because the environment has become pure. So this year's Environment Day will be different from previous years.

Positive Impact of COVID-19 Lockdown on Environment

1) There was lesser travelling done by people after the lockdown in many countries and even industries were closed down and not allowed to function. This led to the pollution in the air dropping remarkably, as there was a marked decline in nitrous oxide emission.

2) In this lockdown there were no boats in the water which led to clearing of water like in areas like Venice, the water became so clear that the fish could be seen and there was better water flow. There is no doubt that the lesser human footfall even the oceans are recovering and marine life is thriving.

3) Animals have been spotted moving about freely where once they would not dare to go. Even sea turtles have been spotted returning to areas they once avoided to lay their eggs, all due to the lack human interference.

4) Plants are growing better because there is cleaner air and water, and because yet again there is no human interference.


The state of our environment is falling day by day due to pollution and global warming. To protect the environment for a better future, we should promote environmentally friendly development in our country.
