Oil spills, poisonous-gas leaks, and out-of-control wildfires have caused devastating damage to the environment and those who live in it. The air provides oxygen, and both humans and the environment have the ability to provide the heat source. Past forest and fire management practices often exacerbate wildfire risk.

Fuel characteristics strongly influence fire behavior and the resulting fire effects on ecosystems. A side-effect of wildfires that also threatens inhabited areas is smoke. The Fire and Smoke Map displays information on ground level air quality monitors recording fine particulates (PM 2.5) from smoke and other sources, as well as information on fires, smoke plume locations, and special statements about smoke issued by various sources.. A properly installed and maintained smoke alarm is one of the best and cheapest ways to be warned early of a potentially deadly fire. https://www.worldatlas.com/articles/what-causes-forest-fires.html Further analysis – visualised below in an interactive map – has shown that, globally, climate change is driving an increase in the weather conditions that can stoke wildfires.
