![]() ![]() ![]() Unfortunately, wildfire frequency and intensity have risen in the past few decades. These wildfires may be the result of human activity (downed power lines, careless use of fireworks, cigarettes or campfires) or they may be caused by naturally occurring lightning strikes. Wildfires are uncontrolled fires that burn in all kinds of ecosystems such as forests, grasslands, brushlands and even savannas. Wildfires are growing more common and larger due to a warming climate and pose a serious threat to our health by adding dangerous levels of pollutants to our air. But there are also serious and growing concerns about natural sources of air pollutants contaminating our air. Most of the conversation around sources of air pollution references human-made sources, things like transportation and industrial exhaust.
