Both the reading and lecture are about the cane toads which harm small animals. They were introduced to Australia to control the population’s harmful insects in 1935, but now, they, themselves, have become a problem. The reading provides three solutions for solving the mentioned trouble and then supports them. The lecturer casts doubt on the claims made in the article and finds all of arguments ineffective.
First of all, the author of reading declares that constructing a national fence would be a good idea because it could already prevent from spread of rabbits in Australia. With this approach, the cane toads will not be able to move new areas. This point is challenged by the professor and she points out the young toads and their eggs find in the rivers and streams; hence, the water currents carry out them easily to other places.
Secondly, the article contends that since the cane toads and their eggs would be gathered and destroyed by hand; therefore, the state should provide some programs to invite the young volunteers for doing this task; conversely, the lecturer claims that volunteers who do not have enough training, fail to discern the cane toads from native frogs because they are similar to each other particularly when the cane toads are young; consequently, the aforementioned suggestion may harm native Australian frogs.
Finally, the reading passage states that researchers or scientists should create a disease- causing virus to prevent from reproducing cane toads. It has to be designed to infect just the cane toad population and no other reptiles or amphibians. This argument is rebutted by the professor. She poses that large number of Australian amphibians or insects are usually transported to other countries with the purpose of research or pet. When the infected insects or amphibians enter the United State, there is a possibility that virus may harm cane toads in The USA. Since the cane toad is a native species in this country; so a plentiful of cane toads will be infected.
