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 reading and listening passages both discuss how to protect frogs. The author proposes three methods. However, the speaker holds these arguments questionable.
First of all, the article claims that frogs are being harmed by pesticides, and if we stop to use it, we could save frogs. Nevertheless, the lecture points out that when we prohibit using the pesticides, we also decrease the ability of competition to our farmer with others because pesticides could let crops grow much great. As a result, the farmers will totally lose the state in the markets.
Secondly, the writer says the second way to save frogs is preventing them away from infection. On the other hand, the lecturer argues that it is very difficult to do the method. Since the methods of the treatments could only treat a frog at one time, we need to capture every individual frog so that we could prevent the infection. Besides, the treatments are not directly available in their children. Thus, we have to capture them again and again if we apply the treatments.
Furthermore, the author states that people can protect frogs by protecting their habitats such as lakes and marshes. However, the speaker contends many breaks are because of the climate change. Actually, Global warming is the main factor to reduce frog's habitats. Practically, even if we directly stop to threaten the habitats, the global environmental change still harm the habitats.
To sum up, all the arguments mentioned in the reading passage are plausible according to the speaker.
