How does this visualization (including caption) advance ethnographic insight?

It conveys the complexity of how toxic landscapes emerge historically and are contested or not by locals and nonlocals. It shows a local activist looking over a city that has been affected by industrial toxicity. The awesome landscape conveys a sense of how this place was once non-toxic, invoking a sense of temporality, as if the activist is looking back and forward through time as the place is affected by toxicity.
