Don’t breathe, it will kill you. Via the South China Morning Post:
The World Health Organization has classified outdoor air pollution as a leading cause of cancer.
“The air we breathe has become polluted with a mixture of cancer-causing substances. We consider this to be the most important environmental carcinogen, more so than passive smoking,” said Kurt Straif, head of the WHO’s International Agency for Research on Cancer.
The agency evaluates cancer-causing substances. This is the first time it has classified air pollution in its entirety as causing cancer.
The most recent data, from 2010, showed that 223,000 lung cancer deaths worldwide were the result of air pollution. The expert panel’s classification was made after scientists analysed more than 1,000 studies worldwide and concluded there was enough evidence that exposure to outdoor air pollution causes lung cancer.
