Causes of Forest Fires Forest fires are one of the greatest natural destroyers of our forests. It has been found that about 90% of forest fires are due to human factors. The most common cause for the forest fires is the carelessness of people. Smokers may start a forest fire by carelessly dropping lighted matches and cigarettes in a forest. Tourists sometimes throw the lighted items in the bushes around or on the ground which cause fire. There are also some natural causes of forest fires. Forest fires can occur due to lightning which burns the trees. Earthquake is also responsible for the forest fires, while other reason for fire is volcanoes and drought. High temperature and low humidity provides favorable conditions to the fire and hence it can start in forests. Since forest fires destroy valuable trees and even kill people, we need to learn the causes and to know how to prevent them.
