Bit by bit over the past few decades, scientists have been building a new understanding of the ways that air pollution threatens human health. Much of their attention has been focused on lung diseases, including cancers. With good reason, it turns out: just last month, the World Health Organization declared air pollution to be one of the planet’s most dangerous environmental carcinogens. But cardiovascular disease is much more common than cancer. Sadly, there is now a pile of evidence, sometimes startling, that air pollution also plays a role in heart attacks and strokes. The new studies suggest that air pollution not only worsens cardiovascular disease — but can also cause it.
