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 introduces the topic of declines and extinctions of frog species. More specifically, the writer discusses different methods to solve this problem. The lecturer in the listening passage disagrees. She believes that these methods are impractical and hard to do it.
In the reading, the author begins by stating that pesticides affect frogs, so the laws should prohibit farmers from using pesticides harmful to frog populations. The lecturer, however, disagrees with this viewpoint. She states that this solution is unfair to farmers, and they are going to be at disadvantage with other zone farmers. Also, they should spend more money on other pesticides, so is not viable economically.
The author also claims that fungus is another problem for the frog population, so it is possible to do treatments to kill the fungus. Again, the lecturer believes there are flaws in the writer's argument. The speaker holds that this treatment is not possible because they need to do it with each frog, so it is not scalable. She says that this solution is complex and expensive.
Also, the reading passage notes that humans use excessive water so the frog habitats are threatened, so the lakes and marshes should be better protected. The person in the listening passage is doubtful that this is accurate. She suggests that global warming is modifying the habitat of frog populations.
To sum up, both the author and the lecturer hold conflicting views about the methods to solve the problem of frog extinctions.
