In recent years, there has been a remarkable decline in the number of frogs,which is caused by environmental changes.To prevent serious consequences,the passage proposed several suggestions to protect the diminishing frog population.But, the speaker in the conversation thinks these suggestions are unpractical and wont help slow down the decline.
First, surrounded by pesticides which does harm to frogs nervous system, frogs should be protected from these chemicals.Therefore,laws should be passed to prohibit pesticides around frog habitats.But,this law is economically unpractical.Compared with those who use pesticides to increase the output of farm crops,those who follow these regulations will suffer economic loss.
Second, to prevent fungus from infecting frogs, humans have to make great efforts to treat frogs with anti-fungal medication on a large scale.However, these treatments have to be applied from one to one.It is expensive and complicate for individuals to receive the medication treatment.Also,this treatment cant be passed onto their offspring.
Third, their wetland habitats are threatened by human activities such as excessive water use and draining of wetlands.However, in fact the real reason behind this phenomenon is global warming.Global warming is responsible for the disappear of their habitats.
