Abstract
This paper explains that acid rain, a relatively new environmental phenomenon, is caused primarily by human created air pollution and that it presents a serious problem because it destroys the environment, including plant and marine life. The paper talks about the effects of acid rain and how far reaching it is as well as the importance of controlling the problem.

From the Paper
"Acid rain is now commonly perceived as a major environmental threat but the term is still relatively new and many are confused about its causes. While there are some other commonly cited reasons including natural sources, the main cause of acidity in rain is air pollution, which increases the composition of sulphur oxides and nitrogen oxides and thus lowering the pH level to less than 7. Air pollution is defined as "the introduction by humankind, directly or indirectly, of substances or energy into the environment resulting in deleterious effects of such a nature as to endanger human health, harm living resources and eco-systems, impair amenities or interfere with other legitimate uses of the environment." [1]"

From the Paper
"What do acids and alkaline truly have in common? The history of the understanding of an acid is relatively old. Dating back to the Roman Empire days, came the word that we derived acid from, acidus, meaning sour. Around the 1800s, French chemists erroneously believed that all acids contained oxygen, including the famed Antoine Lavoisier. Svante Arrhenius, a Swedish scientist in the mid 1800s and a Nobel laureate, did a few experimentations with acids, and came up with concocting a definitive, chemically sound definition of an acid. Later on, in the 20th century, the partners Bronsted and Lowry initiated theories about acids using and published the acid-based concept. The most pragmatic research of acids and bases came from the American chemist Gilbert Lewis. Ever since then, the idea of acids and base has been widely recognized, although the definitions of such terms have been rather controversial."

Abstract
This paper explains that acid rain as an environmental concern is not mentioned as much any more though its danger remains. The paper points out that acid rain is a global problem because wind directions are global. The paper also describes the many adverse effects of acid rain such as its impact on fish larvae. The paper then discusses the parts of the 1990 Clean Air Act, which are devoted to the prevention of acid rain. The paper includes many formulas detailing the creation and effects of acid rain.

From the Paper
"This same idea can be used to explain atmospheric pollution. A few decades ago, the beautiful, Indian monument, the Taj Mahal, started developing cracks in it and the brilliant marble colors started taking on a dull hue. It was discovered that a nearby factory was releasing sulfur dioxide into the atmosphere. The resulting acid rain had deposited on the surface of the marble (CaCO3) converting it into the dull gypsum (CaSO4.1/2 H2O). Calcium sulfate also has twice the molar volume of calcium carbonate. This expansion had resulted in added stress resulting in cracks."

Abstract
This paper discusses the definition and causes of acid rain, as well as its harmful effects on aquatic systems, forests, man-made structures and human health. It also discusses the global implications of acid rain as a migratory form of air pollution and how this presents problems in the regulatory arena, especially from an international standpoint--for example, when acid rain generated by factories in the southern U.S. states is blown by wind patterns across the Mexican border, or vice versa.

From the Paper
"Air pollution is a well-recognized environmental problem throughout the world. Studies have shown, time and time again, that the environmental and health-based impacts of air pollution are both detrimental and undeniable. One of the most important forms of air pollution for our society as a whole to recognize and deal with in an expedient manner is acid precipitation. Because of the very nature of this type of air pollution, the direct and indirect effects of acid precipitation are both far-reaching and difficult to get under control. Understanding more about the causes, effects, and implications of acid precipitation and its impacts on our daily lives is the first step that we all need to take in adopting a more proactive approach to solving this problem."

Abstract
This paper presents a broad overview of acid rain as an environmental problem. Specifically, the paper presents a discussion of the nature of acid rain, its causes, its effects, and the techniques and methods that can be used to correct the problem. The paper ends with a series of conclusions about acid rain that are formulated based on the material that is reviewed.

From the Paper
"Acid rain is any form of precipitation that is measurably more acidic than normal rain. In order to fully understand acid rain some basic chemistry is in order. In this regard it is important to realize that chemically an acid is a substance that gives off hydrogen ions while a base ..."

Abstract
In this paper the author describes a science project in which she attempted to see if antacids had an affect on acid, in particular, acid in soil. In the research, the author hypothesizes, before conducting her experiment, that the antacid will decrease the acidity of the soil. After conducting her experiment, the author concludes that the data collected supports her hypothesis.

From the Paper
"The immediate purpose for this experiment was to determine the relationship between antacids and acidity in soil. As discussed in the discussion, I believe that the antacids would have an affect on the acidity mainly because antacids are neutralizers. The data that I collected did support my hypothesis. Although the data may have inadequacies because of the sources of error, it shows that the acidity of the soil did decrease in response to adding the antacids into the soil. The reason why I believe that the data is inaccurate in some parts is because after adding 35 g of antacids, the results turned back towards the acidic end of the pH scale. It wasn't until adding the 50 g of antacid that the results skyrocketed toward the base end of the scale."

Abstract
The following paper examines why environmental scientists are concerned that the level of acidity in rain and snow has increased beyond its normal levels in the United States. The writer discusses the ways in which this has had a serious impact in several areas, including forests in the northeast and many of the country's most valued monuments.

From the Paper
"Munton (1998) expresses the same concerns. He notes that emissions have already been reduced by 50%. That is an impressive improvement, but perhaps still more than delicate ecosystems can stand. He suggests that we may need even more restrictive interventions in place, and points out that modern society's effects on the atmosphere goes beyond acid rain, which may also affect human health, but to breathable particulates, effects on the ozone layer, and regional haze making particular areas periodically more vulnerable to the effects of airborne pollutants.

"In conclusion, it may be too soon to be satisfied with our efforts so far. Given the tremendous amount of pollution released into the air, a 50% reduction may be a result that looks good on paper but that is still significantly damaging to our environment."

Abstract
This paper introduces, discusses, and analyzes the topic of acid rain. Specifically, it defines acid rain and discusses its effect on the environment.

From the Paper
"The term "acid rain" is really a bit of a misnomer, because acid "rain" can be either wet or dry, and is a global term that covers almost any type of acid that falls from the atmosphere onto the Earth (EPA). Acid rain is often called "acid deposition" by scientists, but the common term most of the public understands is acid rain. Acid rain is a mixture of sulfur dioxide and nitrogen oxides, which result from burning fossil fuels like coal and oil. These chemicals react as they are released into the atmosphere, and join to create a mild solution of acidic compounds that becomes acid rain when it falls to the ground mixed with precipitation, such as rain, fog, and snow, or falls to the ground on its own if there is enough of it in the air. Acid rain is common all over the world, and as our reliance on fossil fuels grows, so does the potential for increasing acid rain."

Abstract
Due to the fact that the world's tropical rainforests are located in areas far from the United States, many people ignore the fact that their future may depend on the future of these forests. Rainforests are being destroyed at an increasingly fast pace, much faster than any other ecological zone on earth. This paper examines the effect of acid rain on rainforests, mainly as a large contributor to deforestation, particularly in localized industrial areas in Africa, China, southeast Asia and northern South America.

From the Paper
"Researcher also believe that we should be concerned about the impact of acid rain on forest soils, as there is evidence that acid rain has already caused significant changes in the chemistry of some sensitive soils. As acid rain seeps through the soils, it can erode vital plant nutrients through chemical reactions, presenting a threat to future forest productivity."

Abstract
This paper explains that the Atkins diet programs recommends the consumption of a diet rich in fats and proteins, while severely reducing the intake of carbohydrates such as fruits and grains, which are a natural sources of vitamins; therefore, sticking to Atkins diet without supplementation will lead to severe vitamin and mineral deficiency. The author stresses that, in addition to other potential health risks, this essential requirement of dietary supplements is of great concern because these supplements are not easily assimilated by the body.
The paper concludes that an ideal way to manage weight is to consume a balanced diet with regular exercises instead of resorting to a diet that totally alters the body metabolism and leaves the patient dependent on a supplements.

"There are definitely health risks associated with the Atkins diet program. The fundamental change in food composition and consequent metabolic process carries a risk of electrolyte imbalance in our body. As Gail Frank, PhD, nutrition professor at California State University states, "Fruits and berries are much more indicative of early man's eating pattern than eating only protein, and we haven't changed all that much physiologically." High protein diet is known to cause the condition of acidic urine, which depletes calcium from the body. The result of calcium loss is a bone degeneration condition known as osteoporosis. Developing kidney stones is another major risk for Atkins dieters."
