Poor air quality is the biggest environmental threat to public health but if you're thinking about of going to where breathing is best, you'll need a passport. A new analysis reports Switzerland has done the best job to clean up air pollution, followed by France, Denmark, Malta and Sweden.

India and Bangladesh were at the bottom of the rankings, along with Burundi, Nepal and Democratic Republic of Congo.
