Air pollution is the name for the mixture of substances in the atmosphere (the air around us that we breathe). Air pollution can cause health problems, by inhaling particles, such as reactive chemicals like ozone, and biological materials like pollens. Air pollution is produced both by human activity (such as combustion of fossil fuels from burning coal) and naturally occurring events (such as volcanoes, dust storms, and wild fires).
