The disappearance of rainforests, means that humans will never lose a large number of species. Species will be extinct. Many species are endangered. Orange fur orangutan (because of the face like the face, is known as the \"forest\") in the past can see anywhere in Asia. Owing to great destruction of their habitat, the life in the tree a gorilla less and less, the only can only be found in Indonesia's Sumatra and Borneo. How many other animals have become extinct or endangered? No one knows, also don't know. People haven't found life on the earth there is 95%, how about them? So far discovered 1.5 million different species of organisms, half of them insects. 10 million species and one hundred million species of insects, however, and most live in the rainforest. Let tropical rainforest disappear means that human beings will lose many: a quarter of the drug from tropical rain forest animals and plants. The U.S. national cancer institute has identified 3000 kinds of plants have anti-cancer function, 70% of them grow in the tropical rainforest. Rosy periwinkle can be used to produce several kinds of medicine to cure childhood leukaemia and Hodgkin's disease. Made from tropical cinchona bark quinine is magic medicine to cure malaria. Si KuiBuShi medicine is to use the Brazil pit viper poison preparing medicament for treating high blood pressure. At least 2500 potential new kinds of fruits and vegetables grow in tropical rain forests around the world. From the rainforest after domestication of animals and plant naturalized in gene can be used to improve native cattle, all chickens are the offspring of the four Asian jungle birds. More than 80% of our food include: coffee, cocoa comes from the tropical rainforest. Rainforest also provide human with rubber tires, chewing gum, gum and olive oil paints and cosmetics. Rain forests have a special book provides a hard rubber used in the golf ball. From Brazil in the bitter with the tree can be directly exported diesel, Brazil 20% of diesel oil supplied with this kind of tree. This kind of phenomenon is the discoverer of MEL. Calvin and therefore won the Nobel Prize. Why to destroy this precious resource? For certain reasons. Logging companies cut down lots of trees, will be a hard wood to sell around the world. Japan, by the way, is the world's largest importer of lumber, use wood production of disposable chopsticks every year, can build 11000 homes. In the rain forest, cut down trees, to build pasture practices were also common. However, the efficiency is very low. According to statistics, to destroy 6 square metre of rain forests in Brazil in 100 grams of Hamburg. People will not think of, rainforest and decent let had the thin and fragile, a few heavy rain washed away all the top soil. In a few years time ranchers have to give up the original ranch, in search of new pastures. Deforestation and the burning of tropical forests far more than just destroy millions of species of plants and animals. The diversity of life on earth destruction means that people live in the atmosphere. This is a chain reaction. Green plants and algae is a special kind of creature. They inhale carbon dioxide from the air, and soil mixed learned or sea water, form a kind of simple sugars, glucose and oxygen. These wonderful changes through the green pigment in plants (chlorophyll absorbs sunlight for chemical reaction, the photosynthesis). Trees to absorb carbon dioxide from the air and save in the form of glucose, can effectively reduce the content of carbon dioxide in the atmosphere. Rainforest trees grow very fast, play an important role to promote the photosynthesis. These trees to absorb millions of tonnes of carbon dioxide from the air. Carbon dioxide is a greenhouse gas, as a result of industrial and automobile tail gas to produce large amounts of carbon dioxide, and thus reduce the concentration of carbon dioxide in the atmosphere is very important. Greenhouse gases absorb the earth's surface, the amount of reflected heat, don't let the heat loss, the result caused a global temperature rise. Using the \"process\" deforestation to build farms with dual consequences. First, cut trees reduced photosynthesis, resulting in increased concentration of carbon dioxide in the atmosphere, it will also reduce life indispensable oxygen content in the atmosphere (photosynthesis oxygen cycle is very important to make sure is not lack of oxygen in the atmosphere). Second, destroying the carbon dioxide fire prevention, environmental worsening. So, finally can only be catastrophic climate change, glaciers dissolved, flooding. This is not a general disaster, it will cause more animals die.

从雨林中得到的经过驯化的动物与归化的植物中
获得的基因能用来改良土生的牲畜，所有家鸡都是亚洲丛林禽类4种的后代。我们80%以上的食物包括咖啡、可可都来自热带雨林。雨林还向人类提供了轮胎用的橡胶，口香糖、油漆和化妆品用的树胶和橄榄油。雨林中有一种特殊的书提供了高尔夫球所用的坚硬的橡胶。从巴西的苦配巴树可以直接导出柴油，巴西有20%的柴油有这种树提供。此种现象的发现者梅尔闻.卡尔文因而获得了诺贝尔奖金。 为何要摧毁如此珍贵的资源呢？有一定的原因。伐木公司砍伐大量树木，将硬木材运往世界各国销售。顺便说一下，日本是世界上最大的木材进口国，每年用木材生产的大量一次性筷子，可以建造1.1万间住宅。 在雨林区，砍掉树木、兴建牧场的做法也很普遍。然而这种做法的效率很低。据统计，需毁掉6平方米的巴西雨林可换得100克汉堡。人们都不会想到，雨林得体让居然有薄又脆弱，几场大雨可冲走所有的表土。用不了几年时间牧场主就得放弃原来的牧场，去寻找新的牧场。 砍伐和焚烧热带雨林远不止毁灭无数的动植物物种。地球上生命多样性的毁灭意味着破坏人们赖以生存的大气。这是一种连锁反应。 绿色植物和海藻是一种特殊的生物。它们吸入空气中的二氧化碳，与土壤或海洋中吸取的水混合，形成一种单糖、葡萄糖和氧气。这种奇妙的变化通过植物中的绿色素（叶绿素吸收日光进行化学反应，即光合作用）完成。 树木将从空气中摄取的二氧化碳以葡萄糖形式存起来，能有效的降低大气中的二氧化碳的含量。热带雨林的树木生长的很快，对促进光合作用起着重要作用。这些林木从空气中摄取上百万吨二氧化碳。 二氧化碳是一种温室气体，由于工业和汽车尾气产生着大量的二氧化碳，因而降低大气中二氧化碳的浓度极为重要。温室气体吸收地球表面反射的热量，不让热量漏失，结果引起全球气温升高。 利用“刀耕火种”毁林兴建农场造成了双重后果。首先，砍伐林木减少了光合作用，最终造成大气中的二氧化碳浓度增加，同时也会减少大气中生命必不可少的氧气含量（光合作用对氧气循环极为重要，能确保大气中不缺乏氧气）。其次，防火毁林产生的二氧化碳，造成环境进一步恶化。这样，最后只能是带来灾难性气候的变化，冰川溶解，洪水泛滥。这不是一般性的灾难，它会造成更多的动物的死亡。
