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 the passage and the lecture discuss about measures that have been proposed to stop the spread of the cane toad in Australia. The passage mentions three ways to prevent cane toad to expand. However, the lecture denies all of measures mentioned in the passage.
First of all, the passage states that building a national fence can prevent the spread of the toad, which been used to prevent the expansion of other harmful species before. Nevertheless, the lecture refutes the approach by pointing out that it may not be an effective way for young toads. Since cane toad eggs and young toads tend to live in the stream, and stream can easily make them flow to the other side of the fence.
Secondly, the passage mentions that hiring volunteers to capture and destroy cane toads is another good solution. Because cane toads can easily be caught in simple traps and can even be captured by hand. Yet the lecture contends that volunteers are not professional, thus, they may not be able to distinguish other types of frog and cane toad. Which can threaten native species in Australia.
Finally, the passage claims that using disease-causing virus can be an effective approach as well, though it will threaten number of reptile and amphibian species. However, the lecture counters the passage by mentioning that this approach could be harmful to species in other continents. Since cane toads often introduce to other continents, and the virus in them may have harmful effects to the native cane toads, which play a vital role in the ecosystem, in America.
