Answer:
The following three human activities are contributing to air pollution:
- Cutting down trees very quickly in order to encourage urbanization.
- Burning of fossil fuels in the coal industry and in transportation.
- Industries produce smoke and gas emissions.
Explanation:
- Any substance that alters the natural properties of the atmosphere, whether it be chemical, physical, or biological, is considered an air pollutant. Air pollution can occur inside or outdoors.
- Common causes of air pollution include motor vehicles, industrial operations, household combustion appliances, and forest fires. Particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulphur dioxide are pollutants of great public health concern. Indoor and outdoor air pollution are significant contributors to morbidity and death and are known to induce respiratory and other illnesses.
- According to WHO data, 99 percent of the world's population breathes air that includes high levels of pollutants and exceeds WHO guideline limits, with low- and middle-income nations seeing the worst exposures.
