As for the assigned article, this week was “Duties to Endangered Species,” it was the last one part in A Sand County Almanac, written by the author Aldo Leopold. I think the main reason why this article was selected as a required assigned article is that it is indeed the most representative article in this book. The main problem facing the book ” A Sand County Almanac” is the problem of the human development model. In other words, since the industrial revolution, human development with science as the main direction has caused and caused all the problems caused by the change in attitude towards nature, which has resulted in reflections on this development model. There are many aspects reflected in the book, mainly because the ways that primitive humans recognize nature are different from the ways that modern humans know nature. Modern humans mainly learn about nature in schools. The primitive way is nature itself to educate humans. To put it simply, nature educates human beings in a love of nature, and this sentiment can produce a worldview based on the whole of nature, which in turn produces a demand for the protection of the whole of nature. Therefore, the land ethics code is generally regarded as an environmental theory based on holism. one good example he gave to us in “The Ecological Conscience” is that but when the state promulgated some policies to help farmers, they also need to take some responsibilities, but they are selective in fulfilling their responsibilities, that is, just do What’s best for you.
“The land ethic as a product of social evolution ”he mentioned. I agree with his point of view. It is precise with the advancement of technology that people are gradually ignoring respect for the natural world. People usually have respect for every member of the community, and of course respect for the community itself. The role of conqueror does not last forever, because it is ethically unfeasible. Therefore, incorporating the land as a whole into the collective concept is only to facilitate people to protect nature rationally. Finally, I’m glad that the author mentioned here that the composition and feedback adjustment methods of each ecosystem are different because the environmental differences caused by various factors will make the environmental protection methods required by different regions different. Imitate blindly. When technology continues to develop, we should develop in a sustainable direction. Because as a part of the earth, we have the responsibility to protect our living environment through our knowledge.
Maybe one day when we break the limit that the earth can withstand, we will inevitably be affected. Besides, I personally it is great thinking but there is no doubt that we can not able to use it purely. For example, we have to change our food chain servicer from feeding to. nowaday we cultivate animals to feed us. when we use the item from the natural world to feed us is also the way to make our cultivate animals lose their role in the food chain.
