I feel that I may have answered this question in my first annotation. The image and its caption undermine the epistemological framework that we employ to understand toxicity, warfare, violence, and ecological destruction. How and why do we know what we think we know? What events have seemed insignificant, only to become catastrphically important in the future?
The visualization and caption combination convey the notion that toxics can sometimes be relegated to the background, particularly when there are other more obviously precarious situations/toxicities occuring in its proximity. Toxicites at times can become everyday and "usual," indicating how people adapt to the toxicities and their effects whether intentionally or not. Perhaps one walks through the landscape and inhales the smoke, perhaps even questioning it, but at the same time that does not render the fire to someone a dramatic indication of danger and its potential to kill. In addition, there is a degree of uncertainty at times regarding who is responsible for toxicities--who caused it, who is responsible for addressing it, etc.
