Forest fires do not arise by themselves. Their cause is rarely natural. Lightnings, for instance, cause only about 1% of forest fires. Unfortunately, the overall majority of fires are a result of human actions. Extremely appalling is the fact that in many cases these actions are deliberate, as arson is the reason for 45% of the whole number of forest fires. Another reason is the carelessness of adults, being the cause of 20 to 25% of all fires in the scale of a year. Sadly, there occur fires caused by careless burning of grasses or stubbles. Other reasons are breakdowns of energetic lines, as well as rail and road transport.
