Human strategies for controlling wildfires have varied over recent decades, ranging from a "suppress at all costs" approach to a "allow all wildfires to burn themselves out" strategy. At one time, human fear and aversion to fires caused professional fire control experts to make every effort to prevent fires and eliminate them immediately where they did occur. However, harsh lessons quickly taught that this approach caused a catastrophic build-up of brush, dense forests and dead vegetation that became the fuel for disastrously large fires when fires inevitably did occur.
