What is Air Pollution
Air pollution is the introduction of
particulates, biological molecules, or other
harmful materials into the Earth's atmosphere,
causing disease, death to humans, damage to other
living organisms such as food crops, or the
natural or built environment. Air pollution may
come from anthropogenic or natural sources. The
atmosphere is a complex natural gaseous system
that is essential to support life on planet
Earth. Stratospheric ozone depletion due to air
pollution has been recognized as a threat to
human health as well as to the Earth's ecosystems.
