The worldwide disruption caused by the COVID-19 pandemic has affected our environment and climate on a very large scale. The global reduction in modern human activity such as the considerable decline in planned travel has prompted a large drop in air pollution and water pollution as well. China has seen a 25 percent reduction in carbon emissions and also a 50 percent reduction in nitrogen oxide emissions because of the lockdown imposed in the country by their government.

Due to the pandemic and hence the lockdown, the travel industry was also impacted very badly as the airlines were stopped for some time. Because of this, there was no air pollution for quite a long time. Reducing air pollution can bring about a positive change in climate as well as COVID-19 risks.

Since travels were banned for some time, water pollution also got reduced. Since the factories were also not operating in the lockdown, no smoke was moved into the water to make it contaminated. In Venice, soon after quarantine began in March and April 2020, water in the canals cleared and encountered greater water flow. The rise in water clarity was due to the settling of sediment that is interrupted by boat traffic and considered the decrease in air pollution along the waterways.

Fish prices and demand for fish saw a great downfall due to the pandemic. As people lingered at home due to lockdown and travel constraints, some animals have been spotted in cities. Sea turtles were detected laying eggs on beaches they once avoided (like the coast of the Bay of Bengal, due to the reduced levels of human interference and light pollution.

People could not move out of their houses, so the roads were also clean. There was no irrelevant littering on the roads. Though the masks that were used by people in these tough days were disposed in the grounds and made the conditions worse.
