Widlfires are seen as a bad thing, but they are bad for the human inhabitants, not for nature. Wildfires occur in many places and what they do is to burn up a ton of dry wood and vegetation and the resulting ash will then be used as a fertilizer for the newer plants to use.
Wilfires are good, but, when they occur near houses, they can destroy a lot of property. Luckily there are the firemen who are ready to save the day. Some of these firemen are sent directly between the burning forests to stop the blazes. Check out the smokejumpers, California’s parachuting firemen.
