What is air pollution?

• A. The depletion of the ozone layer
• B. The introduction of harmful substances into the atmosphere
• C. The increase of greenhouse gases in the atmosphere
• D. The alteration of weather patterns

Answer: (B)

Air pollution refers specifically to the introduction of harmful substances into the atmosphere, which can have detrimental effects on both human health and the environment. These harmful substances can include a variety of pollutants such as particulate matter, chemicals, gases (like carbon monoxide and sulfur dioxide), and biological agents. The primary concern of air pollution is its impact on air quality, which can lead to respiratory issues, environmental degradation, and contributions to climate change. While options discussing the depletion of the ozone layer, the increase of greenhouse gases, and the alteration of weather patterns are related to broader environmental issues, they do not accurately define air pollution itself. The depletion of the ozone layer pertains to the reduction of ozone in the stratosphere, primarily caused by human-made chemicals, rather than immediate airborne pollutants. Similarly, the increase in greenhouse gases is a consequence of certain activities that can also lead to air pollution but is focused on climate change rather than the direct quality and cleanliness of the air we breathe. Alteration of weather patterns relates to climate phenomena and the long-term changes in atmospheric conditions, which differs from the immediate pollution issues associated with harmful airborne substances.
