Air Pollution - GCSE Geography Definition

Air pollution refers to the presence of harmful or toxic substances in the air we breathe. These substances can have negative effects on human health, ecosystems, and the climate. Air pollutants can come from natural sources like volcanic eruptions and wildfires, but are mainly the result of human activities such as burning fossil fuels in cars and power stations, industrial processes, and agriculture. In the context of the GCSE Geography course, understanding air pollution involves examining its causes, such as emissions of carbon dioxide, nitrogen oxides, and particulate matter, as well as its impacts, including global warming, acid rain, and respiratory health issues. Tackling air pollution is crucial for creating sustainable environments and involves measures like cleaner technologies and environmental regulations.
