In recent years, many frog species around the world have declined in numbers or even gone extinct due to changes in their environment. The population declines and extinctions have rious conquences for the ecosystems in which frogs live; for example, frogs help play a role in protecting humans by eating dia-carrying incts. Several methods have been propod to solve the problem of declining frog populations. First, frogs are being harmed by pesticides, which are chemicals ud to prevent incts 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 vere breathing problems. If laws prohibited the farmers from using harmful pesticides near nsitive frog populations, it would significantly reduce the harm pesticides cau to frogs. A cond major factor in frog population decline is a fungus that has spread around the world with deadly effect. The fungus caus thickening of the skin, and since frogs u their skin to absorb water, infected frogs die of dehydration. Recently, rearchers have discovered veral ways to treat or prevent infection, including antifungal medication and treatments that kill the fungus with heat.
Tho treatments, if applied on a large scale, would protect nsitive frog populations from infection. Third, in a great many cas, frog populations are in decline simply becau 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 u 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 u and development, many frog species would recover.

最美大堂经理 None of the methods propod in the reading offers a practical solution for slowing down the decline in frog populations. There are problems with each of the methods you read about.小学生硬笔书法作品
First, riously reducing pesticides in agricultural areas with threatened frog populations is not economically practical or fair. Farmers rely on pesticides to decrea crop loss and stay competitive in the market. If farmers in areas that are clo to endangered frog populations have to follow stricter regulations regarding pesticide u, then tho farmers would be at a vere disadvantage compared to farmers in other areas. They would likely lo more crops and have a lower yield than competing farms.

Second, the new treatments against the skin fungus you read about? Let me explain a couple of problems with this plan. The treatments must be applied individually to each frog. And so using them on a large scale is extremely difficult. It requires capturing and treating each individual frog in a population. Moreover, the treatments do not prevent the frogs from passing the fungus onto their offspring. So the treatments would have to be applied again and again to each new generation of frogs. So applying the treatments would be incredibly complicated and expensive.

You e, water u and development are not the biggest threats to water and wetland habitats. The real threat is global warming. In recent decades, global warming has contributed to the disappearance of many water and wetland habitats, causing entire species to go extinct. Prohibiting humans from using water or building near frog habitats is unlikely to prevent the ongoing habitat changes caud by global warming.

The lecturer argues against the three measures mentioned in the reading passage to solve the problem of declining frog populations. Firstly, the reading passage argues law should be established
to prohibit the farmers from applying harmful pesticides near nsitive frog populations. The lecturer, however, argues that the first measure is not economically pragmatic or fair. Farmers who have to obey stricter regulations regarding pesticide u near endangered frog populations will be less competitive than farmers in other areas and have a lower yield. Regarding the cond method of treating or preventing infection, including antifungal medication and heat treatments, the lecturer explains that it is extremely hard to capture each individual frog and apply the treatments on a large scale. Besides, the fungus cannot be stopped from passing onto the next generation, so the whole project will incredibly costly. Finally, the lecturer objects to the third proposal that human being should refrain from activities such as using excessive water or draining wetlands. She points out that the real threat to frog habitats is global warming which has contributed to the disappearance of many water and wetland habitats. Therefore, forbidding humans from using water or building near frog habitats is impossible to rever the ongoing habitat loss triggered by global warming.
