CHEMISTRY AND EFFECTS OF ACID RAIN
Living in a clear atmosphere has become a very important issue ever since the
start of Industrial Revolution in the 18th century. Transmition from hand manufacturing
to machines and the use of coal as a fuel was no doubt more efficient but had serious
consequences. The biggest negative consequence is the release of greenhouse gases and
its effects on the atmosphere. Perhaps the most recognised problem that revolves around
this issue is global warming. However, acid rain is another big threat to the environment
and human health.

When water becomes too acidic, it dissolves harmful
substances from soil such as aluminum and releases it to water. Aluminum has toxic
effects on animals and often cause them to die. Some of the lakes in North America is
affected by acid rain. One of them is the Plastic Lake, located in Ontario,Canada. The
Plastic Lake is reported to be low in calcium, a mineral necessary for aquatic ecosystems
to survive. One of the reasons for that is the surrounding bedrock doesn't have enough of
the mineral. Acid rain isanother reason for decreasing calcium levels of the lake. Many
organisms require 1.5 mgper lt or higher to survive. Scientists have analyzed calcium
levels to be below 1.5 mg/lt under the effects of acid rain. The harmful effects are said to
be permanent. Even long after the acid rain, necessary minerals in the soil cannot be
Acid rain harms forests and plants. We already talked about acid rain's
effects on soil and water. Same thing applies to forests as the trees and plants feed from
the soil. Acid rain can harm and destroy the leaves but that's not enough to kill a tree.
