70 years since the #airpollution event that kickstarted the way we govern this challenge today (The Great Smog). In honor of this anniversary, I wanted to clarify a few points about this particular historic event “shifted understandings of air pollution”. A thread.. 1/6 
People knew, as they know now, that #airpollution is bad - this is well documented in academic & literary works. The challenge is rather the capacity to do something about it, through regulation & sharing info about how we can protect ourselves tinyurl.com/4zezmdnp @UKHSA 2/6
Regulating pollution via UK, US or EU legal systems, at the expense or trade off of commercial production & activities, requires strong evidence of human health effects. Sadly, this means policy often isn’t strengthened until we experience deaths (like during The Great Smog) 3/5
Beyond this, persistent & compelling advocates help evolve policy. A most notable example is @EllaRobertaFdn, who is championing #EllasLaw in the @HouseofCommons as we speak. Show her your support here: actionnetwork.org/petitions/supp… @GreenJennyJones 4/6
Another essential part is democratizing #airpollution measurement. For example, @Breathe_London - a project across @imperialcollege @MayorofLondon @BloombergDotOrg - enables communities to choose where to place sensors & access reliable pollution data breathelondon.org 5/6
