  4. The toxic ions released because of acid rain form the greatest threat to humans. Mobilized copper has been implicated in outbreaks of diarrhea in young children, and it is thought that contamination of water supplies with aluminium causes Alzheimer’s disease.

  5. crustaceans, insects, and some plankton species begin to disappear. • major changes in the makeup of the plankton community occur. • less desirable species of mosses and plankton may begin to invade. • the progressive loss of some fish populations is likely, with the more highly valued species being generally the least tolerant of acidity. • the water is largely devoid of fish. • the bottom is covered with undecayed material. • the nearshore areas may be dominated by mosses. • terrestrial animals, dependent on aquatic ecosystems, are affected. Waterfowl, for example, depend on aquatic organisms for nourishment and nutrients. As these food sources are reduced or eliminated, the quality of habitat declines and the reproductive success of birds is affected.
