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 lecturer refutes all three claims in the reading, about the measures to stop the spread of American Cane toads in Australia. According to the reading, this amphibian species is introduced to Australia by the farmers to destroy pests that eventually became a threat to native ecosystems. However, the professor presents a counter-argument for each assertion.
First, the reading posits that the surge of cane toads can be prevented by building a national fence. One of the flaws of this idea is the natural habitat of young toads and eggs are rivers and small waterways. Even though a good barrier is made, the leaking ways for the spread of these toads are much higher. So according to the professor, this is unlikely to be effective.
Secondly, the author of the reading suggests that a group of volunteers can capture these toads easily by simple traps or gathering and destroying the eggs of the cane toad. The professor challenges this specific argument by stating that untrained volunteers may probably destroy the native frog species that is even more harmful to society. In addition, it is very difficult to distinguish between a young cane toad and a native frog. This phenomenon worsens the problem even more.
Moreover, the reading explains that introducing a specific virus to kill cane toad will be effective as it may infect only these amphibians. But, the professor disagrees with this idea because this can cause terrible consequences even in Central and South America as these toads are transported to the United States as pets. The cane toads that are infected with these viruses can devastate the native cane toad population leads to its extinction.
