On October 21, Delhi recorded its worst Diwali air quality in four years. Pollution levels spiked at night. PM2.5 concentration peaked at 675, the highest since 2021.
Meanwhile, a Reddit user shared an AI image of the Himalayas visible from Delhi. “Delhi if only Kejriwal was CM right now,” the user wrote. It is not clear if this is a sarcastic look or not.
“I miss him so much,” the user wrote.
Some social media users have been vocal about the difference between AAP’s preventive measures to check Delhi’s Air Quality Index (AQI) and BJP’s.
The Reddit discussion included views from all angles.
“I hope this is sarcastic because frankly it wasn’t when he was in power either. They both did a dirty job as pollution control. So I’m not buying it,” wrote one user.
At the same time, most users talked about Delhi’s concerns about AQI.
“Non-smokers in Delhi are basically doing passive chain smoking 24/7,” wrote one.
“None of the politicians care. They just blame each other. People need to wake up and post about their incompetence to hold them accountable,” another user commented.
“Half of Delhi will die of lung cancer arguing about BJP and AAP,” chimed in another.
Another user wrote: “Pollution and crumbling infra doesn’t care about your religion or caste or who you voted for; it affects everyone equally.”
“We need an educated, enlightened authoritarian government like Singapore to suppress the uneducated and malicious. Anything less will do,” another user commented.
