Idk why but the air quality dropped 3x(300->1200) in the past 2-3 days again in Delhi.
Good thing that the 
has managed to label all anti-pollution protests as "Maoist" so nobody dares to protest anymore since the government can and will throw you in jail for a decade without trial.
Most people don't care and are out enjoying the weekend in this lethal air.
So I grew up in a smallish town and then moved to a city (not Delhi) for work. And I was surprised when I first saw the night sky. It was a glowing dark red, not black with stars. And then some days afterwards a colleague from Delhi complimented us on the good air quality, pointing out that we did not wear masks outdoors or have air purifiers at home.
