Delhi: The Most Polluted Place on Earth

Delhi is under a terrible chemical smog. It's not only the most polluted place on earth currently, but also an extremely nasty far right-wing government in place at the moment. My wife is an asthmatic and she is seriously concerned about whether we have a future there. But certainly I can't imagine actually leaving the country. Maybe it'll be some village in the Himalayas or something next. But Delhi is looking quite tricky to them.
