Deforestation will accelerate extinction of animals, mankind and environment?

A much debated issue is whether the forest destruction will accelerate extinction of animals, mankind and environment or not. Some people argue that deforestation causes extinction. Some others reject this opinion. In this essay, I will argue that deforestation causes extinction for animals, humans and environment for several reasons.
Firstly, deforestation can cause global warming. This is because it may increase the amount of carbon on the atmosphere. As we know that plants, especially in tropical forest, absorb more carbon dioxide for photosynthetic process and produce oxygen. In fact, the earth’s temperature increases significantly over the last three decades. This is because the process of deforestation for over the last three decades is faster than before.
Secondly, forests benefit the economy of a country. The reason for this is that forests can be used as a ecotourism which can contribute to national income as well as local people living near the forests. For example, tropical rainforests provide many suitable facilities for camping, hiking, climbing and other activities which related to natural habit.
Thirdly, deforestation may cause species extinction. As we know that tropical rainforests are a home for animal and plant species living on land. Furthermore, some species are useful for human being. For instance, rosy periwinkle, a kind of plants, contains a substance which can be used to against leukemia diseases.
In conclusion, protecting forests for the future is extremely important because this is not only benefits human but also all species, environment and country. Therefore, maintaining the remained forests from deforestation must be done to save our life.
