After the lockdown due to Covid-19 in many countries, there was lesser travelling done by people, whether by cars, trains or flights. Even many industries were non-functional. This led to the significant decrease in air pollution, as there was a marked reduction in nitrous oxide emission.

Lockdown has decreased the fishing activity, hence the fish biomass will increase. Even the sea turtles have been spotted returning to areas they once avoided to lay their eggs, all due to the lack of human interference.

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

Less litter means lesser clogging of river systems, which is good in the long run for the environment.

In conclusion, though there has been a positive impact on the environment due to the lockdown, there is a fear that once people start travelling, all these positive impacts will soon disappear.

WHAT IS ENVIRONMENT???

The word ‘environment’ refers to the conditions, which is surrounding the ecosystem or the community of living things. What we see,feel. breathe, eat constitutes the environment. The environment supports our lives and the lives of the other species. All living beings need a healthy environment to live a healthy life.

It is the environment that regulates and maintains all biological cycles. Since time immemorial, the growth and evolution of all living forms have taken place with the help of environment.

The food chain, food webs, photosynthesis, greenhouse effect, absorption of UV rays by ozone layer, nitrogen cycle, oxygen cycle etc. are the key environmental processes behind the survival of all species.
