Forests are invaluable to the Earth.
Not only are they places of beauty and recreation, but all over the world people rely on trees for fuel, food, raw materials and medicine. One of the greatest threats to these forests is fire. Fire can destroy not only the lives and homes of the forests' plants and animals, but those of the people whose communities are nearby. It doesn't take much to start a forest fire. A single smoldering match or cigarette butt, a glowing ember from a campfire, a spark from machinery, even lightning, can cause dead leaves and branches to start burning.
