女士們,先生們,晚上好! 今天我要和你們一起來看看這個問題:澳大利亞有多少種獨特的鳥類?也許你們大多數人都不知道,我告訴你,確切的數字是450.鳥兒很漂亮, 非常罕見,是澳大利亞的驕傲,當然它們應該得到很好的保護,但是很多物種面臨滅絕的威脅,你知道導致滅絕的原因,如生物資源過度開采,環境污染等 在我看來,原因之一是瀕危鳥類的交易是一個主要原因,下面我將分享導致鳥類滅絕的原因。Ladies and gentlemen, good evening! Today I'm going to look together with you into this question: how many kinds of unique birds does Australia have? Maybe most of you do not know, I’ll tell you, the exact figure is 450. The birds are very beautiful, very rare, and they are Australian’s pride. Of course they should have been well protected, however, many species are threatened with extinction. Do you knowthe reasons leading to the extinction, such as over-exploitation of biological resources, environmental pollution, and so on? In my opinion, among the reasons, trading of endangered birds is a major reason. In the following content, I’ll share the reasons resulting in extinction of the birds with you.
2014年12月27日“珀斯現在”報道,根據IFAW(國際動物福利基金會)的調查,澳大利亞動物的商業貿易在網站上“蓬勃發展”。出售的動物包括紅尾黑鸚鵡,主要米切爾的鸚鵡和galahs,這些動物只在澳大利亞才有(珀斯現在,2014)。這三個品種在俄羅斯,荷蘭,哈薩克斯坦,烏克蘭的網站上銷售,盡管被禁止商業出口。It was reported by 'Perth Now' on December 27, 2014 that according to an investigation carried by IFAW (International Fund for Animal Welfare), commercial trade of live Australian animals was “flourishing” on websites. The animals for sale included red-tailed black cockatoos, Major Mitchell’s cockatoos and galahs, which are found only in Australia (Perth Now, 2014). These three species were sold on websites in Russia, the Netherlands, Kazakhstan, Ukraine, although there is a ban on commercial exports. Isabel McCrea, who is the Oceania regional director of IFAW said that many animals were exported from Australia to zoos through legal means, of which some unscrupulous zoos sold them or young to pet dealers or collectors. She further mentioned that Australia's unique birds were demanded highly. As they are beautiful, exotic, rare and difficult to be acquired, these birds will be sold at a maximum price of $ 40,000 each (Perth Now, 2014). More mercilessly, many of these live birds sold by traffickers were often dead on the way to be sent to the destination. They did not die soon, many birds died due to suffocation or pressure. Clandestine dealing on remains of endangered birds is rampant in Australia. Illicit trade of birds is found on local mainstream shopping websites, such as eBay and Gumtree. Rampant illegal trade accelerates the extinction of birds (Darby, 2014).
For that reason I proposed above, Australian society should pay attention to the problem of the possible extinction of endangered wildlife caused by transactions, because the protection of endangered birds has a very important significance for all aspects of the society. Firstly, it is beneficial for the maintenance of ecological balance and biodiversity. Each species are an important member of ecosystem, so are birds, through the relationship of food chain, species play the role of interdependence and mutually restraining. Once there is a problem in certain part of a food chain, the balance of the entire ecosystem will be severely affected (Saeki, 2007). Secondly, many endangered birds are the objects of scientific research, they have a high scientific value in zoology, ecology, genetics, modern medicine, bionics (Amoo and Staden, 2013), and mankind currently only have learned a very small part of the value of species. With the development of science and technology, the potential value of each species will gradually be discover本由提供整理,提供,,,,,,相關核心關鍵詞搜索。
