阅读要点概括(Main points of reicading)
1. Several methods have been proposed to solve the problem of the declinations and extinctions of many frog species.
2. First, prohibit farmers from using harmful pesticides near sensitive frog populations.
3. Second, apply antifungal medication and treatments to frogs on a large scale.
4. Third, protect frog habitats that are threatened by human activities, such as excessive water use and development.
听力要点概括(Main points of the lecture)
1. There are according problems with each of the methods that have been proposed to save frog populations.
2. First, the farmers in the areas that are close to endangered frog populations will have a lower yield than other farmers if they follow stricter regulations of pesticide use.
3. Second, applying treatments to frogs could only be individually in a frog population and it could not prevent the frogs from passing the fungus on to their offspring. It is complicated and expensive.
4. Third, the real threat to water and wetland habitats of frog species is global warming. Prohibiting humans from using water or building in frog habitats makes no sense.
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 sensitive 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 use near endangered frog populations will be less competitive than farmers in other areas and have a lower yield. Regarding the second 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 these 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 reverse the ongoing habitat losses triggered by global warming.
