Tweeting has returned to its rightful owners: the birds. These birds come with a cause, too, hoping to make you more environmentally aware.  They're a flock of 10 pigeons, called the Pigeon Air Patrol, that fly around London and inform the Twittersphere of pollution levels throughout city. The small backpacks the pigeons wear were designed by Paris-based company Plume Labs, who last year released apps for iOS and Android to inform users of their environment's air pollution levels. The backpacks consist of lightweight sensors that detect nitrogen dioxide and ozone levels, and attach to little mesh vests that fit over the pigeons' bodies and leave their wings free.
