... examples, the death of many agricultural crops is a serious obstruction, however, acidification causes more setbacks on our planet. Acid rain poses a threat to forests and has a negative effect on soil chemistry. "There's a strong likelihood that acid rain will stunt the growth of Ontario forests, directly affecting the multi-billion dollar forest products industry." Acid deposition has been blamed for causing needle ... and crown die back and eventual death of trees in coniferous and deciduous forests. Acid rain has been associated with the decline of forests and with the changes in so...

... ). Acid levels increase in the spring in lakes. As the thaw arrives the first water that melts has high concentrations of acid which can kill fish by altering their blood chemistry. The spring is also the time when young fish hatch from their eggs. The "acid shock" kills the eggs and emerging larvae (Ostmann 47). Eventually there are no fish left ... ...

... have a certain level of acidity but acid rain has too much acid in it. Acid rain is a complicated problem, caused by air pollution. Acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water. Acidity is measured using a pH scale, with the number 7 being neutral ... ...

A cid rain is formed when certain gases dissolve in rainwater to form acids. Acid rain by definition in the Chemistry book states: "Rainwater that has become excessively acidic because of absorption of pollutant oxides, notably SO3, produced by human activities"(1). There are airborne pollutants that cause acid precipitation for instance ... ...

... direct effects of increasing acidity are, in general, more harmful to the simpler components of the ecosystem. More mature of complex organisms are increasingly capable of regulating their internal body chemistry (May and Eilers, 1987). Many invertebrates, such as zooplankton, that swim in the open water of lakes, are microscopic. Just like fish these are also subject to the effects of ... ...

Furthermore, it does not solve the broader problems of changes in soil chemistry and forest health in the watershed, and does nothing to address visibility reductions, materials damage, and risk to human health. Over time, the basic environment will shift from an alkaline ... ...

There is good reason to believe that long-term changes in the chemistry of some sensitive soils may have already occurred as a result of acid rain. As the acid rain moves through the soil it can strip the soil of any vital nutrients ... ...
