Most forest fires are caused by human carelessness,negligence,or ignorance.
Forest fire prevention, therefore,is mainly a problem of creating a better understanding of the importance of forests,an awareness of the danger of fire in the woods,and a sense of personal responsibility to safeguard the forests from danger.This is not an easy job. (1) ____________________________.Careless smokers are responsible for thousands of forest fires each year.Many of these are started when cigarette butts and matches are tossed from automobiles.Others are caused by hunters,hikers,fishermen,or woods workers who are careless in disposing of their smoking materials.The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas.(2) _________________________________________.The prevention of smoker-caused fires,however,depends upon changing the attitudes and behavior of millions of people who smoke in hazardous areas.The most important natural cause of fire is lightning.This accounts for 11% of forest fires on protected land for the entire nation.In the Western States,lightening causes a much higher percentage of fires than it does in the East.(3) ____________________________.Adequate and well-equipped forces can control them quickly and hold the damage to a minimum.Experiments in “seeding” thunder clouds to prevent or control the lightning itself have been in progress for many years,but new breakthroughs are needed for any significant reduction in the lightning strikes.
