Many tks to above two storeys, THATLL and AMBER0926, thank you!
I revise my composition according to you two's hint and advice. Would you two able to re-correct my composition again, thank u very much!
TOPIC: It is more important to use land for human need than to save land for endangered animals.(second version)
SYLLABUS:
1. 不同意;
2. 承认为人类需求而利用土地资源有些必要;
3. 濒稀物种对科学发展有很高的价值;
4. 对生态系统不利;
5. 结论:不能只图当前利益,而应从长远考虑,否则人类只能自食其果。
As the increasing need of human being, more and more earth lands has been harnessed and explored for the ongoing economic and industries development. Whereas this voracious demands for land from human undoubtedly cause series problems on ecosystem, especially the shrinkage of habitat of endangered animals. Whatever benefits will come out during the exploration of natural land, I strongly agree that the scarce land for endangered species should be more protected and concerned rather than be destroyed for the needs of human.
Admittedly, in order to meet the demands of human's activity, the expansion of land usage is of great importance to social and economic development. For example, a place in the outskirt will be used for building more schools and universities because of the increasing needs of education among citizens. More hospital should be built since a big amount of people fail to obtain basic treatment, especially in South Africa. We need high press road and harbors to deliver cargoes or tourists. In all these cases of imperative needs, people usually never hesitate to raze a hill, eradiate a piece of grassland, deforest woodland, and break original seashore. As a result, the fundamental needs of human being are finally fulfilled, and the lands are also over-explored to some extent.
The over exploration and destroy on the natural land firstly has bad effects on scientific progress. Obviously, we are in the midst of a mass extinction events of unique animals for the swell industries development these years. Some of this extinction might have related with pollution, yet more importantly, the demolishment of animals' habitats greatly threatens these endangered species. With the decreasing numbers of endangered species, we have lost more than just animals themselves. These special and unique species play a huge role in scientific researches. Take the tuatara for example, which live in certain islands of New Zealand. Tuatara is the only extant member of a family of reptiles, and they provide the very specious genetic uniqueness for scientists. The existence of them is probably regarded as a bridge between the reptiles and the mankind.
Furthermore, the overdue use of natural lands would break the balance of ecosystem. Only for the demands of human, the over grazing leads to the shrinkage of grassland; the development of furniture industry cause the loss of Rain Forest in Africa; the over-industrializing and untold manufactures swallow thousands acres of natural lands and emit millions ton of carbon dioxide. A severe consequence will show rapidly. The diverse biodiversity would be damaged at first, because the habitats of many species are thoroughly undermined. Then, more and more species will live at a verge of extinction. When the biological chain had been broken completely, these chain reactions would certainly spread to human kinds. Eventually, human kind or microbe probably is the only surviving animal in the earth damage of ecosystemic equilibrium.
To conclude it, even though it is necessary and agreeable to explore certain lands for human need to facilitate social development in some cases, the harsh and severe impacts on unique system and biological system should be more concerned. A periodical economic boom only benefits a small part of human being, yet in the long run, the protection of habitats of endangered animals will be more meaningful and helpful to massive kinds of species. Otherwise, human kind will become a victim of their own behavior eventually.
