Forest fires this summer there will probably be a lot of forest fires as always during the hot weather. these fires will not only destroy thousands of trees but could destroy homes as well. what are the causes of forest fires? some fires will simply be the result of natural causes, particularly in hot, dry weather. but this can’t explain why fires occur at other times, when the weather is not so hot. for example, when a fire starts in several different places at the same time, it can’t be an it must be because someone started it. we can reduce the number of fires by employing more people to guard the forests, but this can’t be something the government can’t afford.
