There are days in London when the pollution is so bad that an asthmatic sitting in Trafalgar Square might actually breathe easier in Beijing. A recent study calculated that nearly 1,000 people a year die prematurely due to the city’s toxic air.
Fortunately the city now has a new team of tireless pollution watchdogs — or rather, watch-pigeons. Equipped with GPS, nitrogen dioxide sensors and a Twitter handle, the duly dubbed Pigeon Air Patrol, made up of a half-dozen racing pigeons, took flight this March to monitor and tweet about London’s air quality.
