May I present...

This massive, data-driven @FinancialTimes magazine feature with reporting spanning five continents.

We looked at personal exposure to & the human cost of air pollution, which kills more people than car accidents, diabetes or dementia.

We asked correspondents to carry @Plume_Labs monitor for 1-2 weeks to collect our own data, and to test hypotheses such as: Should I cycle, walk or take the tube to work in London?

(spoiler alert)

Whether rich people in São Paulo breathe better air than those living in favelas

Just how much better Beijing's air has gotten since the 2013 'airpocalypse'

Or, which is worse for you in Lagos: the diesel generators, or the traffic?

See what we found! @JoeSinFT produced this brilliant video diary from our correspondents:

Or read the entire thing (and stay, for more glorious @sdbernard #dataviz, as well as stunning photography from @YagazieEmezi, @GillSabrie, Benjamin McMahon, Julia Gillard and Larissa Zaidan)

The whole thing was a massive, multi-month team effort from @lesliehook @neiLmunshi @AndresSchipani @HornbyLucy @hannahkuchler, with graphics from @sdbernard, code for data cleaning and analysis from @maxharlow, art direction from @shannonzoe11 and editing from @estherbintliff

AND THERE'S MORE!

@lesliehook is hosting a Solutions Journalism-style discussion in the comments to discuss how you can protect yourself from air pollution.

It's already kicking off with some really thoughtful notes from our readers

@lesliehook I'm really proud of how our readers and commenters make us better (and our ability/agility to respond)
