It's official: India could soon have the deadliest air pollution in the world.
Air pollution in India has been linked to nearly 1.1 million premature deaths per year. Right now, that's roughly the same as China. But it probably won't stay that way.
In the past five years, government regulation in China has helped level off the number of deaths and even started a downward trend.
But India's stats don't look as great. From 2010 to 2015, the number of premature deaths from air pollution increased from almost 960,000 to more than a million.
That's because of weak government regulation, population growth and a heavy reliance on coal for energy.
Still, India isn't the only place with a pollution problem. In the Western world, Mexico City, London and Paris have had public health concerns, too.
And The Guardian found in at least 15 cities across the world the danger of 30 minutes of outdoor cycling outweighs the benefits of exercise altogether.
