After the industrial revolution, human civilization has been developing dramatically. However, while the civilization is being developed, the environment is being destroyed. The environment is very important for human beings. It provides us with a lot of beneficial things like crops and other things. Therefore, environmental destruction has to be solved quickly. In environmental destruction, deforestation is one of the most serious problems.
Forests function for the earth significantly, so deforestation leads to various, serious environmental problems like global warming, food crisis, and so on. Human beings have to solve deforestation quickly before it becomes widespread. Consequently, we have to clearly, explicitly, and comprehensively understand the causes of deforestation in order to not be unable to find any natural sights or nature itself. Therefore, deforestation is advancing in many developing countries these days due to various incentives. Nevertheless, there are some natural tribulations, which all of the governments should convene to solve this complicated problem.
The first cause of deforestation is lumbering. It is ordinary that a lot of paper is made from a number of trees every year. Actually, papers are very essential for the world. Actually, I noticed that the papers are consumed via a huge number of humans such as in dwellings, jobs, industrial units, and so on, so papers are really imperative in our life. It is not too much to say that the world can't function without paper even though they take vast, massive expanse of our life. In addition, trees are cut down as timber or pulp to build houses, make furniture, or use it as firewood. For instance, some of the industrial countries like Japan prefer using trees for houses or furniture, whereas some of the trees are replaced, like a crop. As a result, a number of trees are required these days by the urban countries. Also, some of the companies over the world cut a lot of trees to use them as papers in their job.
Pollution is a dangerous cause of deforestation as well. Water and soil, bringing grave problems to trees, are really indispensable for trees. Pollution sometimes kills a lot of trees, stays there for a long time, and makes land desolate. Also, in the northern atmosphere, acid rain, resulting from air pollution, threatens forests. In actual fact, strong acid rain can melt stone statues. For trees, acid rain is so injurious that it could exterminate the forests form the earth. This problem is so exacerbated in Europe. In fact, many people have never seen the pictures of withering forests in Eastern Europe.
The final cause of deforestation is agriculture, which is considered as one of the most significant reasons of deforestation. In the developing countries, slash-and-burn agriculture, which is a part of shifting cultivation, is being done. This method happens when a peasant burns the forests and uses the nutritious ash, which is made from the burning forests. The soil, containing the ash from the forests, is very fertile. However, this soil will have lost the nutrition after a few years. Then, as soon as the peasant can't harvest the crops sufficiently, he or she will burn another forest and repeat the procedure again. Due to this agricultural method, many enormous forests have become extinct. The Amazon rainforests as an example have almost disappeared because of the deforestation. Slash-and-burn agriculture is not the only activity that causes deforestation, but also over-grazing is advancing in many districts over the world. Over-grazing leads to desolation, and desolation causes desertification. Desert gradually extends, and it converts forests into deserts. The problem of desertification called "Yellow Sand" occurs and leads to serious problems. That fact supports my idea of the results of deforestation.
