The coronavirus managed to bring its bpvtytybz into literally all spheres of life. Ecology is no exception: as soon as large industrial plants cease their activities, and people quarantine, the nature around them began to transform. Rare birds and animals began to return to many cities, and the overall ecological situation on the planet began to improve. In particular, in Venice, the water in the canals became transparent for the first time in 60 years, and rare birds arrived in Berlin. A white dolphin recently sailed to the water area of the Batumi sea station. Nature very quickly renews itself by itself, and for this it does not need a person. 3-4 years are enough, and we will not recognize the former zone. In Venice, where the canals became so transparent that you can observe the underwater world, there were simply no treatment facilities. Now we wonder why it's clean there. Yes, because the emissions of garbage have stopped. I really hope that the local authorities will draw the appropriate conclusions and try to maintain cleanliness. As for the animals that have begun to populate urban spaces, this, of course, is a positive sign that indicates an improvement in conditions around. But all this will last as long as humanity is in quarantine. As soon as the work resumes, the animals will leave the city and will not have time to acquire offspring. Therefore, neither the chanterelle nor the hog will look into our window and come to visit. Therefore, I believe that even after quarantine, people should somehow preserve the positive ecological situation that has now developed in the world.
