How Acid Rain Affects the Environment
Acid rain is an extremely destructive from of pollution, and the environment suffers from its effects. Forests, trees, lakes, animals, and plants suffer from acid rain.
Acid rain can make trees lose their leaves. Trees can also suffer from stunted growth ; and have damaged bark. The soil poisons the tree with toxic substances that the rain has deposited into it.
Lakes are also damaged by acid rain. Fish die off, and that removes the main source of food for birds. Acid rain can even kill fish before they are born.
1 . Green House Effect
Atmospheric CO2 acts like the glass in a greenhouse, allowing energy in the from of sunlight to enter but absorbing and holding that energy once It has been converted to heat. Several other "greenhouse gases" share this property including methane , and chlorofluorocarbons (CFCs) as well as water vapour. Fossil-fuel consumption and forest fires are the principal causes of carbon dioxide build-up.
Many scientists believe that the greenhouse effect is likely to cause a rise of 1.5 C to 4.5 C in average global temperature by the end of the next century. As the ice cap and glaciers melt in response to atmospheric warming, sea level wall rise threatning coastal cities and flooding coastal wetlands. These threatened ecosystem are the breeding grounds for many species of birds, fishes, shrimps and crabs, whose population may be severely diminished. Another serious consequence of the warming trend is a shift in the global distribution of temperature and rainfall. However , predictions about global warming and its possible climatic effects are tentative and often conflict with each other.

2.Ozone layer depletion
The oxygen molecules in the air that we breath are made up of two oxygen atoms bound together. But up in our stratosphere, there are molecules of ozone, which are three oxygen atoms bound together . This layer of ozone filters out a lot of the sun's ultraviolet (UV) rays, which are harmful to life on earth.
If the ozone layer gets depleted, too many UV rays will reach the earth's surface , causing health problems for animals (like more skin cancer) and harming plant life.
