I have examined this abstraction of a map thoroughly.

I do not see any garbage dumps, recycling facilities, sewage processing, cemeteries, energy production, water production…

I could carry on, but this map means almost nothing with all sorts of factors missing.

Without digging in to the numbers further than just looking at this map, could this be because the relative areas of the factors you listed didn’t pass a threshold to make it? @ezmack what data source was used for this?
