Chile is not the place to go if you want to enjoy fresh air. Extensively polluted, the Particulate Matter (PM10) – particle pollution that can be harmful if breathed into the lungs in large amounts over a long period of time – is at 53.3 micrograms per cubic meter in Chile. This is the highest level of air pollution of all the countries on the OECD list – and over double the average PM10 of 20.9mg. A redeeming factor of the environment, though, is that 77% of Chileans are happy with their water. Income, housing and education are all rated abysmally in the Chilean Better Life Index, too, making this one of the bottom 3 countries for overall well-being.
