Fire can be an incredibly useful tool. We cook our food, warm our homes, light candles, roast marshmallows, shape metals, and create new energy – all with fire. However, using fire as a tool requires extreme awareness of the best safety practices, because it can be incredibly dangerous and destructive. Even a single spark in a dry forest can start a wildfire that engulfs hundreds of thousands of acres.

Although lightning strikes can cause wildfires, 85% of all wildfires in the U.S. are caused by humans: cigarettes, malfunctioning electrical equipment, trash burning, and poorly extinguished campfires are just some ways that humans introduce sparks into their environment. Depending on the weather, these small sparks can wipe out entire forests and cities within days, destroying everything in their path and polluting the air with smoke thick enough to be seen from space.
