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 passage proposes three measures to halt the spread of the cane toad in Australia. however, the professor in the lecture presents compelling arguments to illustrate why she thinks the measures mentioned in the reading passage would not be successful and might even cause unexpected environmental damage.
To begin with, the reading passage suggests that one way to stop the spread of the toad is to build a national fence. however, the professor contends that the fence would not be effective because rivers and streams are very common in the area and they can easily help carry toads and their eggs from one side to the other to establish populations.
Secondly, the passage recommends that toads and their eggs be captured and destroyed by volunteers organized by he government. The professor doubts that this measure would cause unwanted damage to the native frogs that are endangered. Since most of the volunteers would have a hard time telling the difference between toads, especially younger ones, and native frogs, they will be very likely to inadvertently harm the native frogs.
Finally, the professor holds a strongly negative view towards the idea of developing a disease-causing virus to manipulate the cane toad population that has been proposed in the reading passage. cane toads are constantly transported to central and south america by researchers or pet collectors. As a result, if they are infected by the disease, they will bring this disease to central and south america, where king toads reside, thus devastating the local king toad populations and the local ecosystem, of which king toads play a significant role.
