A report on saving forests Serving as a habitat to nearly all life forms, forests, especially tropical forests are renowned as "the lungs of our planet". However, world forests face currently with severe situation like forest degradation and deforestation, which result in a sharp decrease in tree cover during recent 50 years. There exist actually two sides of reasons that could lead to these consequences. On the one hand, since the very beginning of agricultural society, humans were programmed to cutting down trees for farming purposes, for human settlement and then for urbanization. Later by impetus of economic profits, humans clear forest lands for timber, wood or fuel exportation. On the other hand, natural factors like acid rain and forest fires which occur frequently in tropical forests could wipe out many thousands of acres each year in a vast area. Furthermore, extreme climates are more often considered as the prime criminal that forces animals to migrate and reduces the quality of forests ecosystems. Action accounts! To preserve our common lung, to regreen our planet, firstly understand the significance of forests by heart, then teach others and propagate the importance of "recycling" and "restoring". And the key point comes to "act". From now on, be fond of using "environmental-friendly" items and support government to "exploit" adequately and to launch relevant protection policies.
