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 claims that there are three solutions to prevent from decreasing of some frogs species that would be a serious problem .However, the lecturer finds all the idea dubious and presents some evidence to refute them all.
The author argues that by put some rules for farmer of the near of these frogs habitants to use less chemical substances, the frogs will not die anymore. Conversely, the lecturer brings up the idea that these pesticides are dangerous for frogs but it will not economic for agriculture system of that area to not use these pesticides for their crops and it damage their crop markets and will have effect on their competitions. Indeed if strict them to use these material they will loose their crops.so this solution is not efficient for this problem.
Furthermore, the reading passage holds the view that fungus have bad effects on the frog’s skin and by applying antifungal medication and heat them, the reducing of these species will disappear soon. On the contrary, the professor underlines the fact that this method is not a useful one for 2 reasons: first, spreading these drugs in large scales individually will not contribute to a positive result for this problem. second, using this solution is too expensive.
Finally, the reading asserts that by human activities and using the water of the frogs habitants is another reason for their distinction so by protecting these place and do not let people to use more water this problem will solve. In contrast, the speaker dismisses this issue due to the fact that the water shortage is not the main problem. The global warming have disappears this animals and prevent the human to use these waters unlikely change this process.
