All sources of pollution do not come from human activities.
<h3>What are the causes of pollution?</h3>
There are some natural causes of pollution. When dangerous pollutants enter the air as gases, liquids, or solids, air pollution is formed. Although there are some natural processes that can produce air pollution, such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological degradation, manmade sources account for the majority of pollution in the atmosphere.
Burning fossil fuels for transportation, energy, and industry produces the majority of air pollution that is caused by humans. Carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates are typical pollutants released by fossil fuel-burning engines. In addition to particles, carbon monoxide and carbon dioxide are produced by stoves, incinerators, and open burning.
