Even though the United States isn’t the biggest air polluter, it influences other countries by what it does and is still one of the biggest polluters in the world. Most of the pollution is from factories, mobile sources like cars and planes, and natural sources. The United States government needs to figure out something to stop the amount of air pollution it creates. Air pollution happens when gases, dust, fumes, or odor get into the air in harmful amounts. It reaches a harmful amount when the air becomes harmful to humans, animals, or plants that take it in. Pollutants that go straight to the atmosphere and directly pollute the air are called primary pollutants. An example of a primary pollutant is carbon monoxide from a car or sulfur dioxide from the extraction of coal. More pollution can happen if chemical reactions of the primary pollutants happen in the atmosphere. The result is secondary pollutants. Photochemical smog is an example of this (What Is Air Pollution?).
