If the solution of confinement has some positive aspects, these are the drastic reduction of transport and pollution in many cities around the world. The indices of air pollution in cities have rarely been so good.
The decrease in transports has also had an impact on our flora, animals are returning to the cities. There are many testimonials from people who see animals returning to the cities: the waters of the canals of Venice are once again full of fish, the songs of birds can be heard, deer on the deserted avenues, but also at sea with the halt in pleasure boating traffic, and the sharp drop in maritime and port traffic. Dolphins and cetaceans have been observed in Italian ports and the bay of Marseilles.
