Does government has to preserve public owned wildness areas as the speaker claims? I totally agree with the opinion in that wildness areas provide us innumerable benefits and even remote areas may suffer human interferences or even disasters.
To begin with, the remote wild areas could offer us a better environment since wildness areas are parts of the ecosystem. With the abundance of plants and other substances that constitute the natural biosphere, the wildness area could greatly improve the quality of our environment. Though how the entire earth environment and climate function is not clear at present, it is a common sense that the forest, wet land, and other natural wildness areas are playing an important role in maintain the balance of the earth's environment. Some forests besides the desert could prevent the expansion of sand and decrease the intensity and frequency of sand storms. Amazon Forest, the world largest natural area, consumes tones of carbon dioxide and meanwhile outputs amounts of oxygen to the atmosphere which lead to the steady components of the atmosphere. Moreover, the Amazon Forest could decompose many harmful substances which help the refresh of the earth.
Besides, the wildness area could preserve many precious wild animals and plants which are vital in the survival of the earth and also possess potential values. The wildness areas maintain natural and suitable habitats for many wild plants and animals, and the diversity of species are crucial to the survival of mankind. No species could survive only by itself and the world’s biosphere is interactive and dependent. It seems that the natural areas are not crucial to the modern society; however, it is because that we have not realized the benefits of the wild lives. The natural lives make have some special substances that could cure some severe human disease and many modern biochemical technologies are based on the research of the wildlife. The nature life-forms hold a great storage of gene that could have potential benefits to human society. Consider that the crossbred rice has significantly increase the productivity of rice in China and solve the threaten of starvation. And the crossbred rice are the offspring of wild rice, with the technology advancement, we could acquire increasingly benefits form the wildness. Suppose that all the natural areas are either destroyed or occupied by our human residences, there are no forests to refresh the air, no nature field that we could discover some beneficial stances, no wild animals living in the world that make us lonely. And myriad of other negative effects could emerge in the process of the disappearing of wildness areas. It is shortsighted to neglect the importance of the wildness area.
Despite those areas are in extreme remote and few people could visit there, it is very likely that those areas be destroyed by human. And many exiting realities have proved those situations. Since many nature resources, such as the skin of wild animals, some rare wild plants, or the oils, are valuable in current market because of their decreasing amount, some people, with the purpose to pursuit profits, have dramatically destroyed the nature areas, even in remote areas, with the modern equipment, those people could easily acquire what they want regardless of the detrimental consequences. For example, the Tibet goat is the only species of goat living in such a high attitude and its skin is expensive in the international market. Many conscienceless people hunt those goats in mass using machine gun. As a result, the once prosperous specie is now in the danger of distinction. The hunting of wild animals, the unlimited exploit of nature plants, the improper mining and the like could greatly damage the wildness areas. In this sense, we have to protect those areas from the detrimental usage.
Further, we could properly make use of those areas rather than mere protection since the wildness area could preserve many natural resources and resources are indispensable in contemporary society, In the situation that we are facing increasing lack of energy, we could exploit the resources in the wildness areas when necessary. However, those resources have to be properly exploited with the concerning of the well-being of our decedents. It is mean to use up all the resources and cause our offspring suffer the lack of energy and other basic living requirements.
In sum, the wildness areas have to be preserved because they are valuable to our human beings, not only this generation, but also our offspring, and also because those areas may be destroy easily without adopting any protection. |
