air pollution
Dirty sky problem
Air pollution is the presence of harmful substances in the atmosphere, typically from industrial emissions, vehicle exhaust, or burning of fossil fuels.
These contaminants—including particulate matter, carbon monoxide, and nitrogen oxides—pose risks to human health and the environment.
Air pollution levels in the city exceeded safe limits.
The term often appears in discussions of climate policy, respiratory illness, and urban planning.
