The reading claims that the Cane toad, the native amphibian species native to America, was intentionally brought to Australia to protect farmers’ crops by eating the harmful insects. Then, sadly the toad population increased and now threatens small native species other than pests in Australia. The reading then mentioned some attempts to stop the spread of the Toad in Australia, however, the lecturer states that it is not easy to get rid of these species and refutes all the specified solutions.
First, the reading declares that one possible solution is to build a national fence to block the advance of the toads by preventing them from moving into the parts of the Australia which have not been colonized. The professor, meanwhile, makes the argument that this solution will not stop Cane toads from moving to the new places. The professor then mentions there are always rivers which flow everywhere and can carry young toads and the eggs. Therefore, there is no way to stop young toads and the eggs from getting through the fences.
Second, while the reading passage contends capturing the toads by volunteers could be lead to the control and elimination of these species, the lecturer firmly states that this solution would bring about a serious danger for native frogs.
Finally, although the reading asserts that the control of the cane toad population would be possible by developing a disease which harms only can toads, the professor counters by arguing that this virus could affect the native American toads as well. Professor mentions that some researchers and pet collectors always transfer Australian amphibians to the America. Therefore, this might seriously harm and completely eliminate the cane toads from the ecological system in south America.
