How Does Acid Rain Affect an Ecosystem?

The most pronounced effect on an ecosystem from acid rain can be seen in various fresh water environments. Aquatic ecosystems in lakes, rivers, streams and various wetland areas can be devastated by this type of pollution. This is primarily due to the dependency that fresh water animals have on water having a pH level within a specific range. Although there can be wide variation in these levels, they have a tendency to fall between 6 and 8 when life is abundant.

When acid rain hits the water, it will increase the pH levels, but it is the surrounding soil that creates the bigger problem.You can find a quick rundown here Most soil will absorbed some of the excess acid, but in most cases, the acid rain is overwhelming and the run off from the soil will contain high levels of aluminum that results in the destruction of life in the environment. Although there is a range of life that is hurt by low pH levels, it is the fish that die the quickest. Trout and bass both have low tolerance for lower pH levels, but frogs have a higher tolerance. Animals such as snails are more sensitive than fish. However, because animals and plants are all connected together in a web of life, the loss of one species can lead the destruction of the entire ecosystems.
