There is not a nation, a country not known important roles of the jungle in my life. However, today, many places people did not protect the forest, also cutting indiscriminately makes recovery difficult forest resources and increasingly depleted, many parts of the forest can no longer regenerate, the land becomes Bare hills, desert, rain water forming the lines flood wash nutrients, causing flooding, avalanche for the plains of damage to property, life of the people. The role of forests in protecting the environment is becoming the issue and wrap the interest of the whole world. The forest keeps fresh air: due functioning of the trees, the forest is a natural biological plant regularly collect CO2 and O2 offer for. .. Especially nowadays when the phenomenon of warming up of the earth caused by the greenhouse effect, the role of forests in reducing the amount of CO2 is very important. Forests regulate water, preventing flooding, erosion: the forest which acts to regulate water flow decreases the surface turn it into water will leach into the ground and into the groundwater. Fix limiting soil erosion, deposition bed, lake bed, automatic is the flow of the rivers and streams (increasing the amount of river water, mineral water in the dry season, reducing the amount of water streams in the rainy season). The forest protection and fertility potential of the land: in the forest have the flow being tame, to prevent widespread erosion, particularly on steep hills so effects are effective, the thin layer of topsoil should not be physical characteristics, chemistry and microbiology of soils is not destroyed, fertility is maintained. Woods continued to create organic matter. This is reflected in the popular rule: good forest created good soil, good soil and feed back the forest well. If the forest is destroyed, the soil is soil erosion, soil humus loss process and easy going very fast and intense. Estimates in place of the forest being inert down bare soil each year drifted took about 10 tonnes of humus per hectare. At the same time the process of feralitic, iron, aluminum, forming the von, petrified of bees, to strengthen up, making the soil physiochemical properties loss, loss of micro-organisms, does not hold water, prone to drought, lack of nutrients, become very sour, to harden, going to the barren, Rocky and gravel is inert. Represents a rule is also quite popular, in opposition with the rules above, i.e., the loss of forest land forest land and the masterful, masterpiece also suffered decline, we may summarize as follows
