The golden frog is a small bright-yellow amphibian that lives in and around mountain streams in Panama The species is severely endangered because of a fungus that infects the frog through its skin and inhibits the frog's critical life functions, such as breathing. Conservationists have proposed a few solutions to the golden frog's fungus problem. Bacterial Protection First, scientists have identified a natural enemy of the fungus: a type of bacterium. This bacterium produces a chemical that kills fungal cells. Scientists think that they may be able to introduce colonies of this bacterium to the skin of golden frogs. The bacterial colonies would then protect the frogs against the fungus infection Breeding Frogs in Captivity Second, researchers are considering the possibility of breeding golden frogs in captivity and then releasing them in the wild to replenish wild populations The golden frog can develop disease-free in captivity; where it is isolated from the fungus When golden frogs bred in captivity are released in habitats where wild golden frogs have died out, the frogs bred in captivity will give rise to a healthy, fungus-free population. A Natural Defense Third, it is possible that golden frogs w川 overcome the threat posed by the fungus without human intervention. Some golden frogs have what seems to be a natural defense against the fungus. When infected, they increase their body temperature, which slows down the growth of the fungus If this ability to resist the fungal infection spreads among the golden frog population as a whole, the frog population is likely to overcome the crisis and start increasing again.
Recently, there has been a ton of debate about the suggested methods to protect golden frogs from fungus. More specifically, regarding the passage, the writer puts forth the idea that the proposed solutions will be effective. In the listening passage, the lecturer quickly points out some serious flaws in the writer's claims. First and foremost, the author of the reading states that bacteria could help the golden frogs and might protect them from fungus. However, some professionals in the same field stand in firm opposition to this claim. In the listening, for example, the professor states that the effect of bacteria will not last very long, and it will be a temporary solution. She elaborates the bacteria produce the chemicals which kill the fungus at an early stage of colonization. One group of scholars, represented by the writer, thinks that breeding frogs in captivity might be helpful for fungus problems. Of course, though, not all experts in the field believe this is accurate. Again the speaker addresses this point when she states that the frogs released from captivity will soon get infected after contact with other wild animals. Finally, the author wraps his argument by posting that natural defense is the third possible method to protect the golden frogs. The article proposes that frogs will increase their body temperature to protect themself from the infection. Not surprisingly, the lecturer takes issue with this claim by contending that golden frogs consume a lot of energy to increase their body temperature. She adds that this will weaken their health and make their immune system fragile. To sum up, both the writer and professor hold conflicting views about the proper methods to protect the golden frogs from fungus. It is clear that they will have trouble finding common ground on this issue.
