Summarize the points made in the lecture, being sure to explain how they cast doubt on specific points made in the reading passage.

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 are both about how to stop the spread of cane toad in Australia. Whereas the author of the reading states that the spread of cane toads can be stopped or reduced using some ways, the lecturer suggests that those ways would either be unsuccessful or will affect other native species as well. The lecturer casts doubt on the main points made in the reading by opposing each of the three measures suggested by the reading.

First of all, the reading suggests that cane toads can be thwarted from spreading by building a National fence. However, the lecturer disputes this point by saying that this idea has flaws in it. Owing to the fact that cane toads can live in water, the lecturer mentions that a national fence won't be helpful as the water would be flowing through different parts of the country carrying cane toads in it.

Secondly, according to the reading, large groups of volunteers should be allotted the work of capturing and destroying the toads. This is because cane toads are easily catchable using simple traps and even hands. Nevertheless, the lecturer believes that this could adversely affect other native species as well. She mentions that due to the inexperience of the volunteers, native frogs could be destroyed instead of cane toads as it is quite difficult to differentiate between them atleast for the volunteers.

Finally, the reading states that a disease-causing virus can be used to control the populations of cane toad. On the other hand, the lecturer believes that this could affect the populations of cane toad in North and Central America where cane toads are native species. She says that the reptiles and amphibians, that are infected by the virus, could be transferred to America where this could affect the population of cane toads there.
