How air can be polluted by both natural processes and human activities?

Air pollution can arise from natural processes such as volcanic eruptions, wildfires, and dust storms, which release harmful particles and gases into the atmosphere. Human activities, including industrial emissions, vehicle exhaust, and agricultural practices, contribute significantly to air quality degradation by introducing pollutants like carbon monoxide, nitrogen oxides, and particulate matter. The combination of these natural and anthropogenic sources can lead to severe health and environmental impacts, complicating efforts to manage air quality. Addressing both types of pollution is essential for improving public health and protecting ecosystems.
