Answer:After the lockdown was put in place in many countries, there was lesser travelling done by people, whether it be by their own cars, or by trains and flights. Even industries were closed down and not allowed to function. This in turn led to the pollution in the air dropping
Water Quality:
Since there were no boats, whether they be fishing or pleasure ones, plying on the rivers and waterways, the water has cleared up. In areas like Venice, the water became so clear that the fish could be seen and there was better water flow. No doubt, because of the lesser human footfall even the oceans are recovering and marine life is thriving.
Effect on Wildlife:
Again where fish is concerned, the lockdown has seen a decline in fishing, which means that the fish biomass will increase after over-fishing almost depleted it. Apart from that, 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.
