Air pollution & acid rain
Narrated lesson · press play
Burning fuels keeps our world running — but it dirties the air. Learn the dangerous pollutant gases: poisonous carbon monoxide, the sulfur dioxide and nitrogen oxides that make acid rain, the greenhouse gases behind climate change, and how catalytic converters and unleaded petrol fight back.
