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.
In this set of materials, the reading passage states that extinctions of frog populations have serious consequences for the ecosystems and provides several methods to solve the problem. However, the lecturer believes that none of those solution is practical and refute them all by offering several evidences.
First of all, it is mentioned in the article that frogs are being harmed by pesticides and the law must prohibit the farmers from using them. In contrast, the professor argues that the suggested plan is not economically fair because in the competitive market, farmers have to use pesticides to survive. Stricter regulations for farmers near frog habitats create serious disadvantages and they lose more crops. Therefore, this is not a convincing method to protect frogs.
Furthermore, the passage claims that a fungus has spread around the world and causes thickening of the frogs' skin which leads to death because of dehydration. A recent treatment can help frogs to survive. On the contrary, the lecturer contends that the antifungal treatment is impossible for large scales. Researcher must treat the frogs individually which means capture and treat frogs one by one which is not possible. On the other hand frogs do not transfer the treatment to offsprings and it is essential to repeat it again and again. Hence, the solution is too complicated and expensive.
Finally, the reading asserts that since human activities use excessive water and decreases proper habitats of frogs, government should pass a law to protect lakes and marshes. Conversely, the lecturer expresses that the most important reason of reduction of lakes are because of global warming, not human activities. In fact, even if regulations restrict farmers, it is unlikely to change the situation and recover the negative effect of global warming.
