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.
Both the passage and the lecturer discuss the declination of frog populations. The passage provides three solutions to slow down the decrease of frog populations. However, the lecturer disagrees with those statements.
First of all, the writer mentions that the pesticides used in the farm near the habitats of frogs will cause vital effect on frogs. Thus, the government should prohibit the farmers from using pesticides near frog populations. Still, this is very different from the lecturer's claim that this solution is not economical. If the government disallowed farmers in that area to use pesticides, their crop might be harmful by insects and the yield will decline. In this case, those farmers have more disadventage when they compete with other farmers who can use the pesticides.
Secondly, although the writer states that a fungus which spread around the world causes the frogs dehydrate and die, there are several ways to treat this disease of frogs, the lecturer rebuts this belief by point out that this treatment could just treat one frog at a time. Therefore, reasearchers should do this treatment again and again. Moreover, the effect of the treatment could not be passed down to frog's offsprings. Thus, the new generations of frog also should have be treated, which might cause enormous of money.
Third, the author also asserts that the declination of frog is cause by human activities, such as using excessive water or draining of wetlands. So we should protect the water habitats to slow down the decrease of frog. Nevertheless, the lecturer refutes this claim. Protecting the water habitats can not save frogs because the loss of the water resources is caused by global warming. In this case, using less water or protect certain water habitats will not change anything about the recovery of frog species.
