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.
In the reading passage, the author proposes three methods to solve the problem of declining frog populations. The lecturer, however, totally disagrees with these statements with three strong arguments.
First of all, the reading claims that passing laws to prohibit farmers from using detrimental pesticides would significantly reduce the harm they cause to frogs. However, the professor believe that this statement is not practical. She points out that farmers who do not use pesticides would lose competition when comparing to those who use them. Moreover, if farmers are prohibited to use pesticides, the number of crops would certainly decline, which makes farmers less profitable.
Secondly, the reading asserts that by applying some treatments that kill the fungus with heat would help to solve the problem of declining frog populations. Nevertheless, the professor explains that on the one hand, it is difficult for people to cure the infected frogs individually just by the medication and treatments. On the other hand, even though these treatments are applied to those infected frogs, their offspring are still likely to get infected, that means treatments need to be applied again and again, however, this task is complex and the cost is high.
Finally, the professor states that what makes the population of frogs decline is the global warming, but not because their natural habitats are threatened. Thus, she argues that by protecting the habitats such as lakes and marshes, the population would not be recovered.
In sum, according to the discussion above, the professor firmly disagrees with the methods revealed in the reading passage.
