Trees Are Important to Use Trees are very useful to They provide us with wood and other They give us shade and they help to prevent drought and Unfortunately， in many parts of our country， people haven't realized the importance of They cut them down at They are usually too lazy or too careless to plant and look after new As a result， the forests continue to Where there are no trees the rain falls on the surface， causing floods， and carries away with the rich topsoil， in which crops grow so When all the topsoil is gone， nothing remains but worthless The big floods of 1998， in parts of China， have already taught us a good So every one of us must love trees， protect forests， and keep on planting trees each
Protection forest Forest and mankind， mankind intimate partners， is an important part of the global ecological If there is no forest land， most biological extinction， the vast majority of water will flow into the ocean; the oxygen in the atmosphere will reduce， carbon dioxide will increase; the temperature can significantly increased， flood and drought disasters occur Forest， but also can improve the air quality， reduce soil loss， water conservation， reduce the harm of sand blown by wind， reduce noise pollution， beautify the environment and so The forest is precious natural resources， is the human to pillar foundation， and was known as the "lungs of the earth" Why the forest to maintain the ecological balance has an important role? First of all， the nature of all need oxygen to sustain life， and forest is a natural oxygen machine， if the forest and other green plants， is destroyed， the biological survival loses In addition， the forest can regulate the temperature， stop acid rain， dust， noise is attenuated， reducing wind， reduce natural Destruction of forest resources to environmental impact is very serious， loss of ecological Caused by high temperature， air quality is bad， also caused the extinction of wild animals Forest fire is the most dangerous enemy is forest， forestry is the most terrible It will give the forest with devastating Forest fire not only burned forest patches， injury in animals， but also reduce the forest regeneration ability -- a fire， the forest may take decades or even centuries to It can cause the poverty of the soil and water conservation function of forest destruction， even lead to ecological Although now the world science in developing rapidly， however， the human in the uniform of forest fires， but still has not been made a great Forest fire， refers to losing control people， free spreading in woodland， forest， the forest ecosystem and the human bring certain harm and loss of forest fire Forest fire is a sudden， devastating natural disasters， handling more The present situation of the forest， a lot of people do not Please see" -- many tractors， bulldozers rumbled， difficult to count the trees down to the The animals were scared away， plots of land were bulldozed flatIt is human behavior? Love forest! Action bar! Deforestation deforestation forest is human folly， then do not do the harm We must protect the existing forest resources! Beware of forest fires happening again!
China's forest was not much， plus because of The forests of our country are getting less and From the woods to the Recently， I know that the forest can improve the living environment， green can purify the air， reduce environmental Can also provide the work of raw materials and other forest In the disaster areas， flood overruns the reason is because some there is no culture of farmers felling of trees caused water and soil erosion， so that flood will be so fierce Desert， sand flying Originally， this situation is caused by now: the forest is cut The role of forests， some ignorant farmers also not understand it Forest can store water and We feel hot in the summer， and it's more stuffy in the That's because the forest was destroyed， so it's not Where there is a forest， it is like an air conditioner， the trees can block some sunlight， so it will not be too In winter， the trees of the shelter， the woods will not be too You said， the forest is not a cool "natural regulator"Forests have a very beneficial role in the country's interests!It plays a great role in camouflage and concealment on the national defense at the So， the forest is a big hero ""Do you see， the role of the forest is not a lot， a lot of it? So， the forest is really too 我国的森林本来就不多 ， 再加上由于人们的乱砍滥伐 。 我们国家的森林是越来越少了。由森林变化为林子。最近，我知道了森林可以改善生活环境，绿化可以净化空气，减少环境污染。还可以提供工作原料和其它林副产品。在灾区里，洪水泛滥成灾的原因是因为一些没有文化的农民们乱砍树木造成水土大量流失，所以，洪水才会如此凶猛的。少漠中，黄沙漫飞舞着。原来，造成现在这样情景的是：森林被砍光了。人们对于森林的作用，有些愚昧的农民还不明白呢！森林可以蓄水保土。我们在夏天里觉得很热，到了森林里更闷了。那是因为森林被人为破坏了，所以才一点也不凉快。有森林的地方，就像一个空调器，树木可以挡住一些太阳光，这样就不会太热了。冬天，树木的遮挡，林子里面就不会太凉了。你说，森林是不是一个冬暖夏凉的“自然调节器”。森林还有一个很利于国家利益的作用哩！它在边境的国防上，起到了很大的伪装、隐蔽的作用。所以，森林也是一大“功臣”。你看，森林的作用是不是很多，很大呀？所以，森林实在是太重要了。
