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 passage and the lecture are mainly about the decline of frog populations. The author offers several solutions to solve the problem; however, the woman in the conversation does not think it will be work.
The author indicates that frogs would be less affected by pesticide which leads to breathing problems if we can prohibit the farmers from using harmful pesticide. On the contrary, the woman points out since farmers need to use pesticide to produce more crop and get more money. If they do so, people who are not allowed to use pesticide would be a disadvantage and it would not good for the economy.
The reading passage suggests that we could protect frog populations from infection if we use antifungal medication and treatments because the fungus could cause frog cannot absorb water and then die. Nevertheless, the woman in the lecture argues that since the treatment need to use in individual frog and they usually hard to capture every frog as well as they need to do this again and again, that would be expensive, so it is unlikely to do it.
The author claims that many frog species would be recover if we protect water habitats from excessive water use because excessive water could threaten frog habitats. On the other hand, she presents that human activities are not the major problem, just because the global warming, that causes too many waters and then causing some animals extinct.
