>seeing how incredibly smoggy it was. >Now it's very often crystal clear. like the change from somewhat polluted air (even in a semi-rural area where I was then) to much less polluted, in India, during Covid lockdown time. I had read then, that the same had happened in other parts of India too. it was almost like living in pristine nature for a while, in terms of cleaner air. only lasted until the end of the lockdown, some number of months later, sadly. then things were back to (ab)normal.
