Question

What have people all over the world noticed concerning air pollution because of COVID-19?​

Answer 1

Resposta:

If the Covid-19 pandemic brought positive effects to the planet, it can be said that the decrease in pollution was one of them. Worldwide, while people have isolated themselves at home to avoid contamination by the new coronavirus, air quality has significantly improved. A study by the University of Toronto, Canada, released in April, showed that the level of air pollution decreased by 40% in Asian and European cities (Wuhan, Hong Kong, Kyoto, Milan, Seoul and Shanghai) that declared a state of emergency in February. And it was no different in the rest of the globe - much less in Brazil.
