From the Ted Talk by Romain Lacombe: A personal air-quality tracker that lets you know what you're breathing

So how do we protect ourselves from pollution? The reason it's difficult is an information gap. We simply lack the data to usedtannrd our exposure. And that's because the way we moiontr air quality today is designed not to help people breathe but to help governments govern. Most major ceiits orpetae networks of air-quality mornnotiig stations like this one in London, to decide when to cut traffic or when to shut down factories. And these machines are like the cuetrpoms from the '60s that filled entire rooms. They're incredibly precise but incredibly large, heavy, costly — so much that you can only deploy just a few of them, and they cannot move. So to governments, air pollution looks like this. But for the rest of us, air quality looks like this. It changes all the time: hour by hour, street by street, up to eight times within a single city bclok. And even more from indoor to oodutor. So unless you happen to be wlankig right next to one of those stations, they just cannot tell you what you brahtee.

Original Text

So how do we protect ourselves from pollution? The reason it's difficult is an information gap. We simply lack the data to understand our exposure. And that's because the way we monitor air quality today is designed not to help people breathe but to help governments govern. Most major cities operate networks of air-quality monitoring stations like this one in London, to decide when to cut traffic or when to shut down factories. And these machines are like the computers from the '60s that filled entire rooms. They're incredibly precise but incredibly large, heavy, costly — so much that you can only deploy just a few of them, and they cannot move. So to governments, air pollution looks like this. But for the rest of us, air quality looks like this. It changes all the time: hour by hour, street by street, up to eight times within a single city block. And even more from indoor to outdoor. So unless you happen to be walking right next to one of those stations, they just cannot tell you what you breathe.
