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 article states several measures to stop the spread of the cane toad population in Australia. This is because of the rapid multiplication of cane toads and being a threat to native animals that are not pests. The article provides three measures to stop the spread. However, the professor explains that these measures are ineffective and refutes each of the author’s reasons.
First, the reading claims that one of the methods to stop the spread of cane toads are using natural fences as it will block the passage of toads from one part of Australia to the other parts. They cite this reason from the past experience of the fences used for the successful spread of rabbits. However, the professor refutes this point by saying that, the fences won’t stop the spread of toads as many of them are present in streams and rivers and can be easily carried to the other side.
Second, the article posits that the toads could be destroyed and captured with the help of volunteers. The article cites this claim by saying that the cane toads can be easily caught in simple traps and in hands. However, the professor says that, although they might be able to capture the cane toads, many of the volunteers will be untrained and they won’t be able to distinguish cane toads with the native one. This can lead to the destruction of the native species of toads as well.
Third, the article says that a disease-causing virus can be an effective measure to stop the population of cane toads. Moreover, the virus will be specially designed, infecting only the cane toads. However, the professor opposes this point by saying that, most of the cane toads from Australia are transferred back to central and South America. So, it can be disastrous to the ecosystem over there contaminating the rest of the species over there.
