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.
The reading and listening both discuss the issue of preventing the spread of cane toad in Australia. The reading claims that there are 3 ways to stop the spread of the cane toad. While the professor in the lecture suggests that the points above can not hold waters by pointing out 3 reasons.
For starters, the reading supports that building a national fence will be an excellent method to control the population. While the listenind contends that young cane toads and their eggs always in the rivers and streams. Therefore, even you build fences between nations, the river flow will still carry eggs and young cane toads to another side.
Moreover, the reading suggests that toads can be captured and destroyed by volunteers since they are easily being caught by small traps and even by hands. The listening strongly disagrees with the points above by pointing out that most volunteers are untrained so that they may distroy other frogs which are hard to distinguish with toads. Thus this way couldn't work.
Last but not least, according to the reading passage, a disease-causing virus can control the cane toad populations. While the professor disagree with the statement, pointing out that the virus will harm native cane toads in Central America since the virus can be transferred to there. As a result, the whole eco-system will suffer from it. So the method provided by the reading is not practical.
