Water, Soil, and Air Pollution
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Pollution is contaminants introduced into water, soil, or air at levels an environment cannot absorb, threatening exposed populations' health.
Show
Untreated waste entering a river, chemical runoff degrading farmland, and emissions clouding city air illustrate the same mechanism across three mediums.
Watch for
Invisible contamination is still pollution; students often equate pollution with what they can see or smell, missing groundwater and soil contamination.
