Ηow air pollution is any chemicals in the atmosphere that negatively affect human health. Primary pollutants (like CO, VOCs, NOx, SO2, PM, and Lead) as well as secondary pollutants (like Ozone, nitric acid, and sulfuric acid) are included. Regulation of air pollution and technology can mediate the health threat.

The Earth's atmosphere keeps changing, creating an endless cycle of warming, cooling, and recovery

A brief video discussing major air pollutants and air pollution processes. Topics: Primary and secondary pollutants, sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, ground level ozone, temperature inversion, smog, and acid rain.

Air pollution is the introduction of harmful substances including particulates and biological molecules into Earth's atmosphere. It may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Human activity and natural processes can both generate air pollution. Indoor air pollution and poor urban air quality are listed as two of the world's worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report. According to the 2014 WHO report, air pollution in 2012 caused the deaths of around 7 million people worldwide, an estimate roughly matched by the International Energy Agency.
