Air pollution is a phenomenon in which certain substances in the atmosphere reach harmful levels and cause harm to people or things. Good air quality is good for our health, which is why many people choose to live in cities or villages with clean air. In urban centers, the danger to society is the greenhouse effect, acid rain and other climate extremes due to high population concentrations, traffic congestion, dust and smog, plus carbon dioxide exhaled by the human body.
