The reading describes how cane toad is becoming a threat for Australia's small animals and provides three methods to solve this problem. However, the professor in the lecture disagrees with this argument and refutes each of the points made in the reading.
First, the reading states that if the Australian government tries to build a national fence and prevent these animals to move to other parts of the country, this will be a practical way. The professor opposes this idea and explains that young toads and the eggs of this animal live in streams and waters. Once a water flow starts, it will take young toads and the eggs to the other part of the fence. Therefore, the teacher thinks that this method is not practical and cannot stop the population's spread.
Second, the reading mentions that the Australian government can start a campaign and ask citizens to collect toads and their eggs and then destroy them. The professor does not think this is practical. He expresses that people who will join the campaign will be amateurs with no enough knowledge. Since toads, at young ages, look like a specific kind of frog in Australia, volunteers may try to collect and destroy these frogs instead of toads. Consequently, it will extinct the frog's population which already is low.
Third, the reading claims that researchers can develop a virus that only works on toads and it will help to control toads' population without harming other animals. The professor, however, disagrees with this claim and argues that if we spread this virus among toads, it may have horrific results on other countries. Some countries in North America take these toads to do researches on them and if they take one of the animals that are affected by the virus, it will spread in there, and controlling the virus will be another principal problem that will have terrible effects on their ecosystem.
