      How much air pollution is there in the United States?

      In 2017, about 79 million tons of pollution were emitted into the atmosphere in the United States. These emissions mostly contribute to the formation of ozone and particles, the deposition of acids, and visibility impairment.

      Which is worse indoor air pollution or outdoor air pollution?

      However, indoor air pollutants can be even more dangerous than outdoor air pollution! The first step to keeping your home and family safe is learning more about the problem. This article will help by covering 7 common indoor air pollutants. Carbon monoxide is an odorless, invisible gas. It’s produced by the incomplete combustion of fossil fuels.
