Our environment has been suffering from many problems that have plagued earth for years. These problems cannot be ignored or it might have catastrophic results on our environment. Acid rain is a wide spread term used to describe all forms of acid precipitation, rain snow and dust. Acid rain is a serious problem with disastrous effects and this problem is increasing each day. It causes grave damage to our natural wild and aquatic life and can also have an adverse effect on human life.
It causes fish and plants to die in waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. However acid rain on its own is not the biggest problem. It causes many other problems such as aluminum poisoning. As Acid rain is a serious problem with disastrous effects, each day this serious problem increases, this issue should be met head on and solved before it is too late.
This report focuses on what is acid rain, what cause acid, what are the effect of acid rain and try to find how to reduce and eliminate Acid rain causes.

2. What is Acid rain?
2.1 The Definition of Acid Rain
According to acid rain and the facts (2002, p1) acid rain is rain, snow or fog that is polluted by acid in the atmosphere causing damages to the environment ", Acid rain is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry.
Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it effects a variety of plants and animals. The strength of the effects depend on many factors, including the level of acid in the water, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living life that rely on the water.
Dry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind then blows these acidic particles and gases onto buildings, cars, homes, and trees. However, dry deposited gases and particles can be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the combination more acidic than the falling rain alone.
2.2 How to Measure Acid Rain?
Acid rain is measured using a scale called "pH". The lower a substance\'s pH is, the more acidic it is. Normal rain is slightly acidic because carbon dioxide dissolves into it, resulting in a pH of approximately 5.5 while pure water has a pH of 7.0. (Elsom,1987:p34)
3. Causes of Acid rain
3.1 History of Acid rain
During the 1970s many countries started to notice changes in fish populations in lakes and damages to certain trees. It was found that the high acidity levels in the lakes, rivers, bays and streams caused it. Acid rain was identified to be the major cause of the changes and the damages in those environments. The USA, Germany, Czechoslovakia, Netherlands, Switzerland and Australia
DrugsDrugs TOBACCO Tobacco is a plant grown for its leaves that are smoked, chewed, or sniffed for a variety of effects. It is considered an addictive substance because it contains the chemical nicotine. The tobacco plant is believed to have originated in the Western Hemisphere. The cultivated species most often grown for North American and European tobacco products is Nicotine Tabacum. The leaves of the plant are prepared for smoking, chewing, or sniffing. In addition nicotine tobacco contains over
Organic Molecules ChallengeOrganic Molecules Challenge Silicon\'s Reign as King of Semiconductors There is a revolution fomenting in the semiconductor industry. It may take 30 years or more to reach perfection, but when it does the advance may be so great that today\'s computers will be little more than calculators compared to what will come after. The revolution is called molecular electronics, and its goal is to depose silicon as king of the computer chip and put carbon in its place. The perpetrators are a few clever ch
The Chaos TheoryThe Chaos Theory Where Chaos begins, classical science ends. Ever since physicists have inquired into the laws of nature, the have not begun to explore irregular side of nature, the erratic and discontinuous side, that have always puzzled scientists. They did not attempt to understand disorder in the atmosphere, the turbulent sea, the oscillations of the heart and brain, and the fluctuations of wildlife populations. All of these things were taken for granted until in the 1970\'s some American an
OxygenOxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the per
BiologyBiology Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with l
The Effects of Aristotelian Teleological Thought oThe Effects of Aristotelian Teleological Thought on Darwin\'s Mechanistic Views of Evolution Jordan Hoffman The need to understand organisms has been a much sought goal of science since its birth as biology. History shows Aristotle and Charles Darwin as two of the most powerful biologists of all time. Aristotle\'s teleological method was supported widely for over 2,000 years. One scientist remarks that the Aristotelian teleology has been the ghost, the unexplained mystery which has haunted biol
ESTERIFICATION AND HYDROLYSIS ESTERIFICATION AND HYDROLYSIS Experiment #1: Methyl Benzoate by Fisher Esterification Post Lab Organic Chemistry II Lab Section 7515 February 25, 2004 INTRODUCTION The Fischer esterification reaction reaches equilibrium after a few hours. This equilibrium can be shifted by adding more of the acid or of the alcohol. The mechanism of the reaction involves initial protonation of the carboxyl group, followed by attack by nucleophilic hydroxyl, a proton transfer, and finally loss of water follow
TeachingTeaching Background and Setting My teaching practice is being carried out in Blackrock College. This is a large, fee paying all boys secondary school with roughly 1000 pupils from second to sixth year, with first years attending the feeder school Willow Park.
