For years ever since most of the world has been industrialized, the effects of pollution have plagued nations alike. Acid rain is one of the largest contributors to this industrialized form of pollution. Throughout this report an explanation of the devastating effects to the environment caused by acid rain will be given along with what is being done to stop it. Acid rain is made when pollutants arise from the use of coal in the production of electricity, from base- metal smelting and from fuel combustion in vehicles. Once the sulfur and nitrogen oxides from these man made causes are released into the air they are caught by wind currents and are blown hundreds of miles away. The gas pollutants drift along with clouds until the rain eventually converts the sulfuric dioxide into sulfuric acid, and the nitrogen oxide into nitric acid.
The newly transformed acid rain, acid snow or fog, falls to the earth where the effects on aquatic habitats, humans, animals, trees, crops, and other forms of plant life are devastating. When acid rain comes in contact with aquatic ecosystems the chemistry of the effects can be extremely complex. If one species or group of species changes or dies out in response to the acid rain, then the whole entire body of water, especially in lakes, is affected through the predator- prey relationship of the food web. In some places where the acid deposition falls, natural substances absorb and neutralize the acid but in most places they build up and the water becomes as sour as lemon juice.
In these instances the chance of a food web being disrupted are more likely to happen. When the acidity of the water is around the ph level of 6.0 fish cannot lay eggs. When they can’t reproduce and the acidity level grows then the fish out, and when in lakes are extremely difficult to be replaced. Around this acidity level plants also die out and are poisoned. Insects no longer have a food source and soon they are gone.
The water fowl and other birds in the area that fed on fish and insects no longer have a food source and they are the next to go. As the whole entire food web come toppling down the aquatic ecosystems become quiet; quiet as a grave. Acid rain also effects crops and other plant life. Surprisingly though acid rain can actually help out some crops such as strawberries, corn, and tomatoes.
The Industrial Revolution was not only a turning point in the progress of human history, but the start of a great change in the Earth’s environment. Technological advances in industry and mass migration into urban areas led to a rising demand for energy sources, a demand met by fossil fuels. Casper, J. (2010) describes coal as ‘symbolic of the beginning of the Industrial Revolution’, the increased combustion of these ‘dirty’ fossil fuels further polluted the air and enhanced the volume of Carbon Dioxide (CO2) in the atmosphere. Changes in land use attributed to population rise, reduced the amount of photosynthesising biomass on Earth, diminished an important ‘carbon sink’ and concluded to enhance the Greenhouse Effect.
Introduction: The question that the researcher is trying to answer is if there is acidification alters oceanic life due to a change in pH. The hypothesis is if there is a change in pH in the tank then the fish will have altered feeding patterns, stunted growth, and abnormal behavior. Even if there is a slight change in pH distinct abnormalities will occur. This simulation of this experiment will represent a sample for the whole ocean and how pH has affected ocean life due to runoff and toxic waste put into the water.
The result is an acidity level that's harmful to fish, wildlife, plants, and trees. Already, 1,200 lakes in the U.S. have been completely acidified so the lake water is unfit for human use and little or nothing can live in it.Such is the case in the Adirondacks, which are a group of mountains surrounded by many lakes and rivers. They cover over 5,000 square miles in the northeastern part of New York state. It's an area where large resort villages are around the Saranac river and Lake George.
Rain is naturally acidic, due to the CO2 dissolved in it, however when sulphur dioxide and oxides of nitrogen react with the rain water they form sulphuric, and nitric acids which make the rain strongly acidic. SO2 + ½O2 + H2O → H2SO4 It may also take the form of snow or fog. The sulphur dioxides and oxides of nitrogen come mainly from industry. Acid rain is currently a subject of great controversy because of widespread environmental damage for which it has been blamed, including eroding structures, injuring crops and forests, and threatening or depleting life in freshwater lakes.
Many basic descriptions of what nationalism is exist, and defining precisely what nationalism means is not an easy task. This is in large part because the causes and effects of nationalism greatly varies from social context to social context, as the concrete social reality determines the specific shape and character that the nationalism idea takes when it comes to hold a large part of the consciousness of a society (I say the ‘nationalism idea’ for I feel that nationalism is, primarily, in the realm of the ideological). Put more succinctly “Nationalism can be, and has been, democratic and authoritarian, forward-looking or backward-looking, socialist or reactionary” (Kamenka 1976: 3).
Nationalism has a long history although most scholarly research on Nationalism only began in the mid-twentieth century. Some scholars point to the French Revolution of 1789 as the birth of Nationalism. The French Revolution is seen...
The outcomes due to acid rain is most obvious in aquatic habitats. As the acidity in lakes increase, the water becomes clearer and the lives of fish and other water animals decrease. The acidity of the water does not just affect species directly, it also causes toxic substances like aluminum to be released into the water from the soil, harming fish and other aquatic animals. Lakes, rivers and marshes each have their own fragile ecosystem with many different species of plants and animals all depending on one another to survive. If a species of fish disappears, the animals which feed on it will gradually disappear too. If the extinct fish used to feed on a particular species of large insect, that insect population will start to grow, this in turn will affect the smaller insects or plankton on which the larger insect

Many different theoretical approaches exist to study the rise of nationalism throughout history. One approach is primordialism. Primordialism states that nationalism is a natural part of human beings. This field contends that distinct nations have existed since the dawn of time. Primordialism is also described as nationalism is created by people being surrounded by distinct cultural features like religion, custom, and language. This view believes that nations are unchanging and primordial from their beginning (Özkirimli 2000, 64-65). Thus, ethnic and national ties are given at birth. One subset of primordialism is the perennalist approach. This approach believes that modern nations are clear descendants of their
On the contrary she is seen by the granddaughters as surprisingly “cool” (Meyer, 74) and accepting of their quirks. While the grandmother was “Confucian born and trained, and a Buddhist and all” (Meyer, 74), she seems to have dropped these strict ideals and somewhat accepted her granddaughters American culture. For example, at the beginning of the story, one of the granddaughters, Lea, was wearing a rather provocative outfit for a fancy party she was attending later, and while the grandmother told her that she looked like a “high class whore”, she then admits it was merely a teasing compliment, and on top of that, instructs her granddaughter to “do the cha-cha for [her]” since she “didn’t get to do much when [she] was young, with [her] clubbed foot and the wars and everything else” (Meyer, 73). Her Confucian ideals put utmost importance on how once carries themselves(1), and dressing like this would definitely create conflict. This is the first concrete example of the grandmother not only accepting her granddaughter’s different lifestyle, but also showing some envy, or at least understanding why it would be enjoyable. While a traditional Confucian upbringing would not allow anything close to this, the grandmother overrides this and starts to see the perks of enjoying
Obesity is a modern epidemic in America and is starting to become our society’s “norm.” According to an article in Progress in Health Sciences, childhood obesity is the most frequent eating disorder (Koukourikos). There are several factors that contribute to the childhood obesity epidemic. Should we solely shun the parents of obese children for this? No, we should not. There is not one single person to blame, but several people, along with our society. Family, friends, and schools all play a very important role in teaching children about healthy food choices and exercise. Children may have a greater risk for obesity due to genetic factors. We need to constantly remind our children how important it is to maintain a healthy lifestyle so that
In the atmosphere carbon dioxide is chemically neutral, however when it dissolves in seawater it reacts with H2O to form a weak carbonic acid. Over recent years, oceans have become more acidic because of the increase of carbon dioxide in the atmosphere. The acidity of the ocean is determined by the concentration of hydrogen ions which are then measured on a pH scale – where the greater the level of hydrogen ions, the lower the pH (Askins, 2008). As the pH of the ocean drops from the pre-industrial value of 8.2 to 7.8 by 2020, ocean acidification is predicted to have a great effect on the ocean. Many of the aquatic organisms are very sensitive to the acidity of water, and as a result there will be effects at all levels of the marine food web (Balch & Utgoff, 2009). The carbonate shells of marine animals for example can dissolve in acidic waters. Also coral reefs will also be impacted negatively by increased acidity in addition to the effect that warmer waters are already having on them (McCarty, Wolfenbarger,
When looking at different themes throughout history, it seems as though nationalism has been brought to the center stage. While some philosophers have supported nationalism, and other criticized it, the ideals of nationalism have been the driving force of many pivotal events through out history.
Acid rain is when chemicals like nitrogen and sulphur-dioxide are released into the atmosphere and react with the water vapour, and acid pours in form of rain. This is very dangerous because it destroys infrastructures and some buildings, and also dissolves the human
If there is not enough oxygen in the water, it may lead to the death of many organisms, reduction in their growth or even failure to survive. The pH is a measure of how acidic or alkaline the water. It is defined as the negative log of the hydrogen ion concentration. According to Fondriest Environmental Inc, a well-known Fundamental Environmental organization, the pH scale goes from 0 to 14. As the scale of pH decreases, water becomes more acidic. Many chemical reactions inside aquatic organisms are necessary for survival and growth of organisms. At the extreme ends of the pH scale, (2 or 13) physical damage to gills, exoskeleton, fins, occurs. Changes in pH may alter the concentrations of other substances in water to a more toxic form. Examples: a decrease in pH (below 6) may increase the amount of mercury soluble in water. An increase in pH (above 8.5) enhances the conversion of nontoxic ammonia (ammonium ion) to a toxic form of ammonia (un-ionized ammonia). (Fondriest,
