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 the lecture both talk about the cane toad that is threatening the native species in the Australia and how to control its effective aggression.Whereas the author of the reading states some proposes to stop the spread, the lecture suggests that those proposals may not as effective to control the toad as the reading expected. The lecturer casts doubts on the main points in reading by providing three reasons.
First of all, according to the reading building, a national fence can block the toad from the area where they yet to access and it can control the further colonization of the toed population. However, the lecturer disputes this point. He says that cane toad used to lay their egg beside the water area like rivers and streams which can carry the eggs and young toad to the other sides of the fence
Secondly, the reading states that cane toad and their eggs can be captured and destroyed by the volunteers through a campaign.Nevertheless, the lecturer refutes this argument. He argues that the untrained volunteers can have a dangerous implication since they can not differentiate the toad eggs thus may destroy other native species' eggs.
Finally, the reading claims that developing a disease can be an effective way to control toad. On the other hand, the lecturer believes that this might have a very negative effect since it could also hamper the other species and also since the Australian species often transfer to the other continents this disease could disperse through the whole world which might hamper the other vulnerable species.
