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 article is about decrease in frogs population and states that this is threatening and has dangerous consequences for humans and ecosystem. It also proposes several solutions for this problem. However, the professor in the lecture rejects each reason and asserts they are not efficient.
First, it suggests that frogs are being harmed by pesticides, which are chemicals that farmers use to protect their crops such as corn from insects. Conversely, the professor mentions this solution is not practical since it will have negative economical effects. Since farmers rely on these materials to protect their products, reducing the use of them will have severe disadvantages for them, including losing crops and a lower yield, that leads to farmers' inability to stay in market and compete with rivals.
Second, the article talks about a fungus that has spread around the world with deadly effect that causes frogs to die of dehydration. It claims that some treatments can be used to kill fungus with heat. In contrast, the professor announces this solution also ineffective, because it has to be applied individually to each frog and it is impossible to use the broadly. Also for each generation they should be applied again, which make the solution even more impractical.
Thirdly, the article states natural inhabitants of frogs are threatened by human activities. Most frogs live in marshes and and lakes which are being dried out because of excessive water use or draining them to make them suitable for development. But the professor states that although this might be true to some degrees, the main threat to frogs habitats is global warming, that may lead to extinction of entire species. So if any action is to be done for saving frogs inhabitants, it should address the global warming.
