When the air in the park is worse than at the side of the road, that’s a new low. If you’re a Londoner, type in your postcode at Asi Open Data to find the nearest park where NO2 emissions don’t exceed 40 micrograms per cubic metre.
This is not just diverting; it’s potentially life-saving. We know pollution can be a factor in developing lung cancer. Now new research shows that it may also shorten the life span of lung cancer survivors. Researchers are joining the dots between pollution and dementia, too. We tend to give pollution polite names like “haze” and “smog”. We should call it “the killer”.
