Air Planet Acts

Air pollution is the introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause harm or discomfort to organisms. Air pollution occurs when harmful or excessive quantities of substances including gases (such as ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies, and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. All acts that help avoid or reduce air pollution or acts that improve air quality are linked to this sub-category.
