The Invisible Epidemic: Why We Must Stop Ignoring India's Air Quality Crisis For years, we have treated air pollution in India as a seasonal nuisance—a "winter irritant" confined to Delhi and the northern plains. We complain about the smog in November, buy masks, and then forget about it as the skies clear slightly in spring.
