Air pollution, primarily caused by human activities like burning fossil fuels for energy, poses significant health and environmental risks. It releases greenhouse gases such as carbon dioxide and methane that contribute to climate change, creating a feedback loop where higher temperatures exacerbate air quality issues. Smog is a major form of air pollution with two types: sulfurous smog from coal combustion and photochemical smog resulting from reactions between sunlight and pollutants like nitrogen oxides. Toxic pollutants released during fuel combustion can lead to severe health problems including cancer and reproductive issues. Solutions include reducing fossil fuel usage in transportation, manufacturing, and electricity generation to improve air quality while combating global warming.
