This set of the material in the both reading and lecture is about controlling population of cane toad, amphibian species. The reading mentions that applying the mentioned strategies would be convincing and workable. On the other hand, the lecturer states that the author's explanation is unlikely to be successful because getting rid of cane toad populations would be too demanding.

First, the passage posits that one of the most effective plan to reduce cane toad populations might be to construct a national fence. The lecturer opposes this point by saying that there are lots of young cane toads and their eggs, which exist in rivers, can be relocated by the river stream. In this case, a new population will be established in another place in which might be out of the position of that national fence.

Second, the reading describes volunteers' assistance would play an important role in declining the toad's populations. In contrast, the speaker explains that applying this plan might lead to destruction of other native species since some of these volunteers are unable to recognize the cane toads from other native species due to lack of knowledge and sufficient train.

Finally, the passage claims that developing a disease-causing virus may be another effective way of controlling their populations. The lecturer refutes this point by explaining that this approach is more likely to put American native species in danger of extinction by spreading this virus among other native species in USA, which means disturbing ecological system in USA.
