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.
The article and the lecture are both about the methods to protect frogs from declines or even more seriously, extinction. However, the professor disputes the ideas that are provided in the article and the reasons are as follows.
First, the author of the article points out that the governments can use laws to prohibit the farmers from using harmful pesticides near frog populations because insects that are killed by such pesticides can be eaten by frogs. However, the lecturer does not agree with that. To be more specific, she argued that this method is not economically practical and is unfair for the farmers who need to obey the pesticide restriction. Those regulated farmers may lose more crops due to the insects which are damaging them and they will lose the competition in the markets against farmers from other areas.
Secondly, the article mentioned that there are antifungal treatments that can be applied on a large scale to prevent skin thickening caused by a kind of fungus. Nevertheless, the lecturer rejects the opinion. She suggests that those treatments have to be applied to each frog individually, so it is extremely complex and difficult to apply them to a large scale. Besides, this method may cost a large amount of money and time because of the need for individual treatments.
Finally, the article believes that people can prevent frogs from extinction by limiting excessive water use and development on frogs' natural habitats such as lakes and wetlands. However, the lecturer disputes the idea. She says that the biggest threat of the frog habitats is not the issue the article has mentioned, but, in fact, is global warming. Global warming causes the disappearance of lakes and wetlands and leads to the declines and extinction of frogs. Therefore, posing restrictions of excessive water use and development on humans does not really help frogs.
