I remember reading an article about people in India seeing the Himalayas for the first time in 30 years because of lockdown and reduced traffic/pollution. Now, sadly levels are back up and a lot of places are still locked down. Sad. I suppose it’ll get worse than it was before as covid ends.
I read the article HERE.
The same thing happened after 9-11 when all the planes were grounded for 3 days.
