Carl lives in a country where there has been a lot of air pollution. A local news repor just announced that many of the fish in
the local lakes have started to die off. The reporter suggests that this is because of the air pollution, but Carl thinks that is impossible because fish live in water, not in the open air. Who is correct and why? The reporter is correct. Air pollution causes acid rain, which can kill fish by lowering the pH o the lake water O The reporter is correct. Air pollution causes smog, which cause death from respiratory illnesses. Carl is correct. The lake water provides a barrier to keep air pollution from reaching the fish below. Carl is correct. Unless a fish emerges from the water, such as when fish sometimes jump, they will not be affected by air pollution.
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. ... A decrease in pH values from 5.0 to 4.0 means that the acidity is 10 times greater.
