Fires and biomass burning

Wildfires and prescribed (i.e., controlled) fires are major sources of air pollution, greenhouse gases, and aerosols. In the southeastern US, prescribed fires are used extensively for agriculture, silviculture, conservation, and wildfire mitigation. In Florida, about 8% of the land area burns every year. Although widespread, these prescribed fires are rarely in the news because most are small and they occur when weather conditions allow safe burning and minimize impact on sensitive locations, like road, schools, hospitals, and cities.
