    1. Living in cities like Beijing and Delhi is comparable to smoking over 30 cigarettes a day

      This claim lacks citation or calculation. If, as is more often assumed, microparticles (PM2.5) are the main culprit in air pollution, the claim sounds hugely exaggerated. Even with beyond-index pollution records of almost \(1mg/m^3\) in Beijing (see e.g. Wikipedia), total microparticle (PM2.5) intake would be: $$15,000 liter/day * 1mg/1000liter = 15mg/day$$ This would be a bit more than one cigarette per day, not 30.

      See this post or this Q/A for more elaborate discussions on this question.
