Explanation
Forest fire is an event where there is a fire with a high intensity that burns the forest environment either in part or in whole. Forest fires will certainly have a negative impact on the environment, not only the forest itself but also the surrounding environment.
Forest fires are divided into 3 types, including surface fires, canopy fires, and canopy fires. Explanation of each type, so surface fires are fires that occur on the forest floor and the fire is very easy to spread but still relatively easy to extinguish. Furthermore, canopy fires are fires that burn canopy of staple plants, especially flammable trees. Finally is canopy fire, this fire will burn the organic layer under the forest floor, this type of fire occurs in a very long time and the propagation of the fire is very slow.
Forest fires occur because of 2 factors, namely natural factors and human factors. For natural factors usually due to long-term drought which causes sparks, while human factors are usually due to negligence and deliberation such as littering cigarette butts, burning wildly and to open new land.
Forest fires result in the appearance of thick thick smoke containing various harmful gases which are certainly very unhealthy when inhaled by living things. Various diseases can be triggered due to forest fires, including ARI, lung cancer, asthma and other respiratory diseases.
Forest fires are events that often occur in our country, natural factors and our lack of concern trigger these events. For this reason, we should protect our forest environment, remembering that forests are the lungs of the world, which is very obligatory for us to protect.
