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

The reading mainly talks about many frog species have declined in numbers and some are
even extinct. Several methods proposed to help solve the problem. However, the listening
challenges what is stated in the passage by providing three strong reasons.
Firstly, in the reading, it is said that frogs are killed by pesticides and other chemicals. If laws
prohibit farmers from using pesticides near frogs, it would reduce the harm of pesticides
cause to frogs. In contrast, the listening holds a view that prohibiting pesticides is not
economically practical. To state it more clearly, it will cause severe disadvantage for farms to
plant, farmers may loss crops if they don't use pesticides.
Secondly, the passage asserts that antifungal medication and other treatments will help
prevent frogs from infection. However, the woman maintains an opposite opinoin that using
medication is not practical because it is needed for every single frog. It's impossible to use
medication in large scale. If the frogs have offspring, we'll need to use medication on their
offspring again.
Finally, the author believed that frogs' habitates are under threaten because of human
activities. But the woman believed that frog habitates are threatened by global warming rather
than human. So it's useless to prevent human activity
