If this is related to local air pollution then what is the biggest producer of that pollution? I mean are there any coal plants or blast furnaces near her home? Was there a construction site pouring concrete or demolishing a building and creating toxic dust? Is the traffic especially bad? It is far simpler to move pollution away from locations than it is to reduce them in the first place. Therefore knowing what the source of the pollution is far more important than the pollution itself. If this death really was caused by global air pollution then good luck, nobody can help you when China and India are ramping up their pollution, certain industries might never stop emitting CO2 and capturing CO2 in the air will never be economical without a huge carbon tax.
