In recent years, many frog species around the world have declined in numbers or even gone extinct due to changes in their environment. These population declines and extinctions have serious consequences for the ecosystems in which frogs live; for example, frogs help play a role in protecting humans by eating disease-carrying insects. Several methods have been proposed to solve the problem of declining frog populations.
First, frogs are being harmed by pesticides, which are chemicals used to prevent insects from damaging farm crops such as corn and sugarcane. Pesticides often spread from farmland into neighboring frog habitats. Once pesticides enter a frog’s body, they attack the nervous system, leading to severe breathing problems. If laws prohibited the farmers from using harmful pesticides near sensitive frog populations, it would significantly reduce the harm pesticides cause to frogs.
A second major factor in frog population decline is a fungus that has spread around the world with deadly effect. The fungus causes thickening of the skin, and since frogs use their skin to absorb water, infected frogs die of dehydration. Recently, researchers have discovered several ways to treat or prevent infection, including antifungal medication and treatments that kill the fungus with heat. Those treatments, if applied on a large scale, would protect sensitive frog populations from infection.
Third, in a great many cases, frog populations are in decline simply because their natural habitats are threatened. Since most frog species lay their eggs in water, they are dependent on water and wetland habitats. Many such habitats are threatened by human activities, including excessive water use or the draining of wetlands to make them suitable for development. If key water habitats such as lakes and marshes were better protected from excessive water use and development, many frog species would recover.
It is studied that recently there has been the decline of the frog populations as their environments change. While in the reading passage, three methods is proposed by the author to help protect frogs, each of them has its flaws as the lecturer points out.
Firstly, the author suggests that stricter laws should be enacted to protect frog habitat from pesticide pollution. As those habitats sometimes may locate near the farmlands, the frogs in contact with the pollutants may have severe breathing problems as their nervous systems are attacked. However, the lecturer claims that if this method is adopted, the farmers who are confined to this law will have disadvantage in competing with others. Thus, it is concluded by the lecturer a not economic method to put into practice.
Next, the reading proposes that the antifungal medication and treatment is needed to kill the fungus that will make frogs dehydrated when infected, In the contrary, the lecturer holds the negative idea about this medication for two reasons. To begin with, the process is complicated since this could only apply to each individual, which makes it even harder for capturing and treatment. Moreover, the medication would not be able to be past down. Thus, the treatment needs to be applies over and over again to each generation. In conclusion, the lecturer thinks this method is practical.
Lastly, the author suggests that the habitat of frogs, like the lakes and marshes, should be protected from excessive water use and development. In the other hand, the lecturer argues that the main threats to their habitat is not water exploitation, but global warming. Thus, the effect would be limited by the protection of their habitat. Instead, the lecturer thinks this decline of frog population by global warming is unlikely to change.
