It is predicted that the concentration of CO2 will triple to what the pre-industrial average of 280 ppm. Currently, according to the CO2 detector on Mauna Loa Observatory is registering 398.78 ppm. Kaster (1998) states that,” Of the 7.1 gigatons of carbon released each year about 3.3 Gt C accumulates in the atmosphere.” An increase of air pollutants is a result of continued use of fossil fuels. Air pollutants such as carbon monoxide, nitrogen oxides, sulfur oxides and hydrocarbons are produced as fossil fuels are used (Union of Concerned Scientist, n. d.). Carbon monoxide causes headaches and aggravates people with heart disease. Nitrogen dioxide and nitric oxides create smog, a yellowish-brown “cloud” layer that settles on the ground. And these substances irritate lungs causing issues like bronchitis and pneumonia. Sulfur oxides and nitrogen oxides are the primary components of acid rain and snow that affect plants and buildings. Hydrocarbons are another pollutant made from burning fossil fuels. Smog is also tropospheric ozone, which affects lungs, and crop yields. In addition, fossil fuels produce small particles that irritate the lungs. Pollution also impacts water and land. Oil spills leave shorelines uninhabitable for animals. Coal mining adds water pollutants by adding sulfur…

Air pollution is the introduction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment. (Godish)…
Over the past years, carbon dioxide has been at the center of debates in regards of the negative effects it has on the environment. CO2 is considered as a pollutant, it has the ability to turn fresh air into toxic air. Industries and automobiles are two of the major entities known to cause CO2 pollution. Automobiles emit CO2 by burning fossil foil for energy. The most frequent utilized fossil fuel worldwide are coal and oil. “Over 90 percent of the fuel used for transportation is petroleum based, which includes gasoline and diesel” (EPA). In addition to being a pollutant, CO2 is considered as a greenhouse gas. This means that it has high tendency to cause on climate change.…
Lets start with “Air Pollution” which is created by both human and natural resources including but not limited to CO, SO2, most hydrocarbons, most particulates, CO2, NO, NO2, HNO2, HNO3, H2O2, SO3, H2SO4. Air pollution is a big atmospheric issue that continues to become a greater concern, especially when it comes to the health of living things including humans, animals and plants on our earth.…
Air pollution affects everything from agriculture and ecosystems to human health, on a global scale. The five major air pollutants are ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide (Donnatelle, 2010). A majority of these pollutants are the result of human action. One example being coal power plants. These plants release greenhouse gas emissions and particle air pollution. The burning of the coal creates pollutant byproducts. Other forms of industrial pollution, exhaust fumes, burning wood, and several forms of indoor air pollutants result in air contamination. The combination of various air contaminates can be extremely toxic. The pollutants irritate the lungs and may even cause respiratory diseases and cancer in humans (Donnatelle, 2010).…
You probably know that Carbon Dioxide, a greenhouse gas, is the main pollutant that is warming the Earth. Let me tell you that Carbon Dioxide represents 85 percent of all gas emissions caused by human sources. Globally, the largest source of carbon emission is the combustion of fossil fuels like coal, natural gas and oil for energy. On the other hand, electricity production is the biggest generator of carbon emissions; transportation comes in the second place, followed by industry, cars, planes, power plants, and other human activities that involve the burning of fossil fuels, such as gasoline and…
Bibliography: "Air Pollution." GEG Project RSS2. GEG Project, n.d. Web. 29 Nov. 2012. This informative web article details the process of air pollution. In defining air pollution—when specific compounds in the atmosphere reach a point to which they cause change in the environment—it is observed that large quantities of these pollutants can be harmful. Natural processes such as volcanic eruptions decay of organic matter, and wildfires generate small amounts of air pollution. Humans, however, create far more substantial quantities that have greatly impacted the environment. An increase in outputs of pollution is the cause of acid rain, global warming, and even health risks such as heart disease and stroke.…
When the Industrial Revolution began in Great Britain in the 1700’s and later spread to its surrounding countries, the effects that mass production and the ways in which production were fueled were not being looked at from an ecological viewpoint. The main focus of the Industrial Revolution was not to preserve the earth 's natural resources and the surrounding environment, but rather to speed up production so that in demand items were available in abundance and cheaper to the world 's consumers. The environmental damage caused by this revolution was not seen until around the 1800 's, and by that time most of the damage was already irreversible.…
In our state we have a growing problem of air pollution. It might not be as clearly visible in some areas as others but the fact is that air pollution is still there affecting us in some way, shape, or form. Air pollution has been known to cause illness and/or death, which many people may not be aware of. There are two main causes of pollution in our state. One main cause of air pollution is natural. Natural pollution is windblown dust, pollen, fog, etc. The other main cause of air pollution is humans. Air pollution caused by humans is the chief concern and the most serious form. Most of the human pollution created is from industrial work, cars, trucks and airplanes. The causes of pollution can go on and on, and scientists constantly are discovering new elements that add to air pollution. The most harmful cause of air pollution is from automobile emissions. People drive automobiles everyday to get from "Point A to Point B". If automobiles did not exist, the air would most likely be cleaner, but we would not be able to travel long distances in short periods.…
Carbon oxide and Nitrogen oxide are one of the many air pollutants this world is having problems with. As for carbon oxide and nitrogen oxide they fall into the category of a primary pollutant, or as so I believe. The reason for why I believe this is because when nitrogen oxide is let out and exposed into the air it can harm the growth of our plants and crops which results us to lose quantities of our food being grown. Also if nitrogen oxide is inhaled it can cause health complications such as asthma. It is a harmful gas that’s created when chemical interactions such as nitrogen and oxygen are combined together and in some cases it can become life threatening. Carbon oxides are the gases produced my carbon monoxide and carbon dioxide. It is a colorless, odorless, and tasteless gas that’s extremely poisonous and if exposed to it in any way or matter in can begin to reduce the blood's ability to transport oxygen. Carbon dioxide is associated with global warming because carbon dioxide is made up of fossil fuels such as gasoline; methane and propane containing mostly carbon in it. When these fuels are burned, they react with oxygen and produce carbon dioxide which is exposed out into the air which in conclusion leads to the pollutant letting sun lights heat and energy in but doesn’t let that same heat energy out.…
Exploring the links between ecosystems and human well-being, this article looks at the effects of industrial pollution on water quality and their impacts. Informed by a recent UNEP report “Clearing the Waters: A focus on water quality solutions”, released on World Water Day, 22 March, 2010, and also by other UN reports, the article highlights pathways to arrive at the sustainable management of human activities and processes within ecosystems, for improved water quality globally. Humans are dependent upon ecosystem services such as air, water, food, and for provision of materials for development and construction. While the importance of ecosystems and their services cannot be underestimated, a wide range of human and natural processes have altered the way they function, eroding their capacity to deliver these vital ecosystem services for human well-being. Water is vital for life, but also supports ecosystems, e.g. inland water ecosystems…

Carbon Dioxide is a colorless gas having a faint, sharp odor and a sour taste; it is a minor component of Earth’s atmosphere formed in combustion of carbon-containing materials, in fermentation, and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. In the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years.…
Based on the past experience in the area of environment and resource studies, the environmental problems such as the accumulation of heavy metals in water and sediment in the canal and river have been the major focus in the study area. The study shows that the major source of heavy metals that accumulate in water and sediment is industries. As a result, it motivates the researcher to choose the research topic about industrialization is responsible for the world's environmental problems. This current research will certainly be useful for the researcher. It is because this research is closely related to the researcher's future study, particularly in the area of environmental engineering.…
