Acid Deposition more commonly referred to as acid rain is a growing problem in our world. Acid rain pollution is growing by the day, part of the problem has to do with human’s ignorance of the situation. Most people are unaware of what acid rain is and how dangerous it can be to our environment. What is acid deposition? Acid deposition is a deposit of water vapor formed in the atmosphere (Encarta Dictionaries). Acid rain is caused when carbon dioxide floats through the atmosphere and combines with water. The H2O of water and the CO2 mix to form H2CO3, an acid solution. There are many negative effects of acid rain such as damages to humans, forests, lakes and rivers, and wildlife. Aside from its negative affects there is one positive affect of acid rain.

There are very few positive aspects associated with acid rain. The only benefit researchers think they have discovered about acid rain is its reduction of global warming. The new study shows that the natural production of methane gases by microbes in wetland areas helps limit global warming. Global warming itself will only fuel the production of methane as heating up the microbe’s causes them to produce even more methane. But the new model suggests that sulfur pollution from industry reduces this. This is because sulfur-eating bacteria also found in wetland regions outcompete the methane-emitting microbes. Experiments have shown that sulfur deposits can reduce methane production in small regions by up to 30 per cent by activating the sulfur-eating bacteria.

There are many negative effects associated with acid rain one of its effects can be seen on buildings and human structures. You will notice this on buildings that appear worn down and outdoor statues made from marble or other calcite materials. The acid interacts with this stone and eats it away. Acid rain deteriorates the paint on sculptures, buildings, and cars as well lowering their value. Dry deposition of acidic compounds can also make building and other sculptures dirty. These problems leading causes companies to lose money due to an increase in maintenance cost.

Many lakes and streams examined in a National Surface Water Survey (NSWS) suffer from chronic acidity, a condition in which water has a constant low pH level. Contamination of our lakes and streams is another problem associated with acid rain. Rain naturally seeps into groundwater and runs through soil to surface water, such as streams and lakes. On its way toward groundwater, the acid rain is often neutralized by the minerals it encounters, but runoff into surface water can pose more dangerous problems. First of all, all lakes and streams have a general pH level that allows natural organisms to survive in the local area. If this balance is made too acidic, it can kill some kinds of smaller organisms, which in turn affects the entire food chain.

Acid rain also affects human in an indirect way. Being exposed to acid rain through swimming or just being caught outside on a rainy day can lead to danger. The chemicals that lead to acid rain sulfur dioxide and nitrogen oxide is what makes it hazardous to human health. As these pollutants are released and travel through the air they enter our lungs as we breathe. Scientific studies show relationship between the increase of acid rain particles and increased illness and premature death from heart and lung disorders, such as asthma and bronchitis.

It can be concluded that acid depositions negative effects outweigh its good. While acid deposition is said to reduce a major problem in our world which is global warming it is also responsible for creating several more problems. In order to reduce this problem we can take action by cleaning up smokestacks and exhaust pipes, using alternative energy sources, restoring damaged environment, and taking individual action. But even if acid rain could be stopped today, it would still take many years for its harmful effects to disappear.
