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 contends that several methods would be able to solve the problem of the decrease in frog populations, and presents several evidences that seem to uphold the claim. However, the lecture disapproves the reading passage by claiming that the solutions offered are not practical and actually possess problems. The points made in the lecture will be elaborated in more detail below.
First of all, the lecture counterpoints the reading passage, which asserts that frogs are being harmed by pesticides that are used to prevent insects from damaging farm crops, by explaining that reducing the use of pesticides is not economically practical and is actually unfair. Farmers need to exploit pesticides in order to stay competitive with other farmers. If stricter regulations are held against farmers who grow crops near frog populations, then it would be a severe disadvantage for them, compared to farmers in other areas.
Secondly, while the reading passage maintains that fungus that has been spread around the world causes detrimental effect on the frog population, the lecture refutes this assertion by mentioning that the treatment needs to be applied to each individual frogs, making it highly unlikely to be the solution for the problem. Each frog would have to be captured and treated, and because the medication is not passed on to their offspring, the same treatment would have to be applied to the next generation and the next.
Last but not least, the reading passage claims that natural habitats are being threatened and is causing frog populations to decline. However, the lecture disputes this reason by commenting that human activities in lakes and marshes is not a biggest threat and inhibiting such activities would certainly not save the frog population. The actual main cause is due to global warming. Global warming is causing large amount of water to disappear, which leads to multiple species becoming extinct and frogs merely being one of them.
