Water, Soil, and Air Pollution
Captions available
The idea
Pollution is contaminants introduced into water, soil, or air at levels an environment cannot absorb, threatening exposed populations' health.
In practice
Untreated waste entering a river, chemical runoff degrading farmland, and emissions clouding city air illustrate the same mechanism across three mediums.
Where people slip
Invisible contamination is still pollution; students often equate pollution with what they can see or smell, missing groundwater and soil contamination.
