The cane toad is a large (1.8 kg) amphibian species native to Central and South America. It was deliberately introduced to Australia in 1935 with the expectation that it would protect farmers’ crops by eating harmful insects. Unfortunately, the toad multiplied rapidly, and a large cane toad population now threatens small native animals that are not pests. Several measures have been proposed to stop the spread of the cane toad in Australia.
One way to prevent the spread of the toad would be to build a national fence. A fence that blocks the advance of the toads will prevent them from moving into those parts of Australia that they have not yet colonized. This approach has been used before: a national fence was erected in the early part of the twentieth century to prevent the spread of rabbits, another animal species that was introduced in Australia from abroad and had a harmful impact on its native ecosystems.
Second, the toads could be captured and destroyed by volunteers. Cane toads can easily be caught in simple traps and can even be captured by hand. Young toads and cane toad eggs are even easier to gather and destroy, since they are restricted to the water. If the Australian government were to organize a campaign among Australian citizens to join forces to destroy the toads, the collective effort might stop the toad from spreading.
Third, researchers are developing a disease-causing virus to control the cane toad populations. This virus will be specially designed: although it will be able to infect a number of reptile and amphibian species, it will not harm most of the infected species; it will specifically harm only the cane toads. The virus will control the population of cane toads by preventing them from maturing and reproducing.
Both reading passage and lecture discuss whether preventive measures should be taken for reducing the number of the cane toad in Australia. The former argues that there are three ways of decreasing the cane toad, but the later refutes each of these points.
First of all, the author of the passage claims that through constructing the national fence, it is possible to thwart the moving of the cane toad in other areas and in the past, Australia used this technique for stopping the expansions of rabbits. However, the lecture contends that it would be very unsuccessful project. As the eggs of the cane toad and many youngs are staying in the stream and they can move to another places through water ways, there would be no fruitful benefits of building fence in some areas.
Secondly, the text asserts that volunteer efforts can be used to capture and destroy ted eggs and young teds, which is a very easy task. In contrast, the listening counters that if the people have not any training regarding this, they can capture native specices like Australian original young frogs rather than ted. Therefore, this is not a good way to remove animals.
In third, the reading passage states that it is possible to make hindrance of maturing and reproducing of cane ted populations by pushing disease-contains virus. Though it infects other species, but causes ultimate distress to ted only. On the other hand, the lecturer mentions that sometimes certain animals are transporting to another countries for example, reptiles and amphibians are trasferred to America. Hence, if these animals contais dangerous virus, then it can trasmit it to the native American species like cane ted which is vital wildlife creature for maintaing whole ecosystems.
