In “Let Them Die” Kenan Malik argue that dying language should not be prevent. Many language died and will die when their last speaker die. Some people are trying to preserve dying language. In author’s view, it is not possible to preserve dying language and dying language are not language at all. He list several examples to demonstrate his point. In my opinion, we should let them die. We should try to protect them first. If they can not stop dying, that do not have to regret. According to the essay, author divided it to four part, first part is the Introduction of the topic: Language Extinction. Secondly, he explain some promote the campaign to preserve linguistic diversity. Then author’s counter arguments. Finally, author make the conclusion: we should let those language die in peace. The essay has a catchy title. Make the reader interested in this essay. Also the essay has a clear text structure. In paragraph two to four, author list the consequences of language death. Language death results in the loss of unique biological and ecological knowledge; reduces knowledge about human language and mind; death of unique cultures. Author describes those in order to laying the groundwork for his following paragraph. In fifth and sixth paragraph we could clearly know some languages lose their function of communication. After that, in seventh to tenth paragraph, the preservers based their argument on the romantic notion of human differences and cultural differences, but the author believed that such belief is also the basis of a racial view of the world. These all shows why those language was dying or will be die. Less and less kind of language prove that the world is increasingly unified civilization and the progress of technology. That is why I support the author’s point of view. In this essay, author shows how do language become extinct. First of all, language become extinct when a community finds itself under pressure to integrate with a larger or more powerful group. Secondly, the community is pressured to give up its language and even its ethnic and cultural identity. Third is outright genocide. Undeniable thing is people is doing something to protect the endangered language. In my opinion, the language die is the law of natural selection. Sometimes we may not have ability to resist these happening. All in all，we do not feel too sad because of those dying language. It is the law of natural selection, also prove the world is increasing unified civilization.
