The reading states that the large cane toad population is threatening small native animals in Australia. The cane toad is native to Central and South America and has been introduced to Australia in order to protect farmers’ corps by eating the insects. The author proposes some measures to stop the spread of the cane toad in Australia and provides three reasons of support. On the other hand, in the listening passage, the professor explains that the proposed measures are unsuccessful and probably would have unwanted consequences, and refutes each of the author's reasons.
First, the reading claims that a national fence will prevent the cane toads from spreading to those parts of Australia that they have not yet colonized. Moreover, his approach was examined successfully for rabbits’ population controlling in the early part of the twentieth century. However, the professor argues that the national fence might stop the crane toad spreading but it would be inefficient in the places in which streams and rivers flow through the fence. Since, the young toads as well as toad’s eggs can penetrate to other side of the fence and eventually the other side’s toad population will be increased.
Second, that if the Australian government were to organize a campaign of volunteers to capture the toads and destroy the collection of toad's eggs, these collective effort would prevent the spread of toads is refuted by the professor in the listening passage. She states that these untrained volunteers would endanger the native nondestructive frogs. The native frogs of Australia are resemble to the crane toad when they are young, thus it is not easy to discriminate them.
Third, the article claims that an especially designed virus which is developed by researchers will be able to control the population of the crane toads. This virus is especially designed to prevent the crane toad from maturing and reproducing. The professor casts doubt on this approach by saying that it would have terrible consequences to the cane toad’s original habitats. She explains that the virus would infect the crane toads as well as a number of reptile and amphibian species in Australia. The researchers and pet collectors get these species transported from Australia to Central and South America, the native habitat of toads. In other words, transported virus might attack the native crane toads and consequently destruct their population. As a result, the whole ecosystem would suffer from the transported virus.
