2.1 Air Pollution
Pollution is the action of contaminating air, water or land by harmful substances which are natural and man-made wastes. Such wastes degrade the air, water or land which reduces is quality and usage. Sources of pollutions are automobiles, increased chemical wastes, nuclear wastes and accumulation of garbage in landfills. Air pollution is one type of environmental contamination which has remained as a main problem in the society. Major contaminants include carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), hydrocarbons (HC) and particulates. These contaminants pose critical environmental and health threats. These are not only experienced locally but internationally as well. Other parts of the globe experience worse cases than the other due to certain conditions of the environment. (Baje, Calong & Cudiamat, 2014)
Global emissions of carbon dioxide (CO2) from fossil fuels have been increasing by 2.7% annually over the past decade and are now 60% above 1990 levels, the reference year for the Kyoto Protocol. A range of different options that could help in improving the quality of the air and for mitigating climate change is considered worldwide including Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU). CCS, however, faces a few technical and economic barriers that it must overcome before it can be deployed large scale, one of which is that it is unprofitable. CCU, on the other hand, is profitable due to the conversion of
With the increasingly global acceptance that carbon dioxide (CO2) is contributing to an irreversible change in climate, a progressively growing international population and an ever more reliance on fossil fuels, a way of reducing carbon dioxide emissions into the atmosphere is essential. Currently renewable energies are not established enough to meet the demand that fossil fuels serve so that’s where carbon capture and storage (CCS) comes in.
Anthropogenic emissions of CO2 as well as their effects on the climate increase on a daily basis. With the current situation of things in the world, it is unlikely for renewable energy resources to replace fossil fuels as the major sources of energy anytime soon (Wennersten et al, 725). Therefore, Carbon capture and storage (CCS) seems to be one of the most viable options to reduce the current rate of anthropogenic emissions of CO2. Sustainability is a key factor in determining whether or not CCS becomes a major technology in limiting anthropogenic emissions of CO2. That is, the benefits of CCS should outweigh its costs. In this paper, I 'm going to look at carbon capture and its feasibility as a key factor in limiting anthropogenic emissions of CO2.
Pollution and Environmental Degradation are things that the large majority of humans contributes to some small or large way on the daily. Whether it is our mode of transportation, throwing a piece of trash on the ground, buying products made from trees, and to be perfectly honest the concentration in which we live, by which I mean the proximity of the average residents in which we reside. These all seem like regular everyday things that are just normal. But in the past things like these were so beyond the norm that they would seem alien and impossible.
Since the very first textile production line in the 1700s to Apple products being made overseas in China, factories have plays a significant role in our world since the beginning and continues to do so. The Industrial Revolution was a stepping stone in Americas history and opened a door to new inventions to make lives easier. It began with the invention and application of machinery for production and peak in the production of machines made by machines. Factories have indeed made production efficient and increased the number of jobs. However, like all good things there is a negative side. Factories are a source of nonpoint pollution, meaning the pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Non-point source air pollution affects air quality from smokestacks. Which is a problem because factories contribute to both water and air pollution harming our environment as it still continues to operate all over the world. So how do we know if factories are doing more harm than benefits for our environment?
FOR PREVENTING THE EFFECTS GLOBAL WARMING PLAYS ON OUR ENVIRONMENT, AND THE REDUCTION OF CANCERS THAT HUMANS DEVELOP FROM POLLUTION.
Pollutants are impacting aquatic organisms disposed by daily human activities and natural occurrences. An extensive amount of pollutants such as pesticides, heavy metals, and hydrocarbons can result in direct significant damage, e.g. death. However lower levels of these harmful substances can be stored in an organism and increase as it continues and follows up the food chain, a process called biomagnification or bioaccumulation, having the greatest effect on the top predator of that food chain. A common result of the pollutants can lead to stress, changing of the immune system, inhibit lysozyme activity, damage gills, metabolism, and growth. Other factors include an excessive amount of nutrients in the environment. Nitrogen can make its way into aquatic ecosystems when there is an increase in nitrous oxide in the air, allowing eutrophication. Algae and bacteria feed off the nitrogen, so a high number of these organisms appear and use oxygen around them as the feed, causing hypoxic zones, or dead zones. Acidification, an increase in the ecosystem’s pH acidity from acid rain, which occurs from an increase in CO2 from air pollution. Aquatic organisms have a range of tolerance, and water with high acidic pH will lead the organism out of the range of tolerance, resulting in stress of the organism, and eventually death. Further studies are being pursuited to see larger impacts of globalized pollution on aquatic species and their ecosystems.
People have heard of pollution, but what some don’t know is that there are many types of pollution. Pollution can have different consequences depending on what kind there is. In the world so far there are only nine types of pollution that have been recognized. Although this can be negative to the world it’s also affecting the health of people as well. In order to understand what pollution can do to you and the world you need to know the types that are causing the harm.
Having over 121,000 kilometers of rail lines throughout China and 228,218 kilometers throughout the United States transcontinental travel throughout the countries has become immensely accessible. The use of such transports has subsequently resulted in an emittance of pollutants such as nitrous oxide, particulate matter, and carbon dioxide. The increase of the anthropocentric activity dictates the positive feed back loop of the total emissions of criteria pollutants.
The focus of this research paper is air pollution. Simply put, air pollution may be defined as the introduction of harmful materials such as particles or/ and biological molecules into the earth’s surface. The materials that are introduced in the earth’s atmosphere are harmful in the sense of having the potency to cause death and disease to humans, and flora and fauna. Apart from this fact, the earth’s atmosphere is a complexity of gaseous system that occurs naturally and is critical for the sustenance of life on the planet. The 2014 World Health Organization Report states that air pollution was responsible for the deaths of more than 7 million people globally, in 2012.
These types of sources we us in our everyday lives like cars, trucks, and buses, and many that we use but don’t realize like when we us electricity made from a power plant.
According to the World Health Organization, approximately 7 million premature deaths annually are linked to air pollution. Air pollution is described as “a mixture of solid particles and gases in the air” (“Air Pollution” MedlinePlus). This form of pollution mainly occurs from the burning of fossil fuels, noxious gases from vehicles, manufacturing chemicals, ground-level ozone (a reactive form of oxygen and a primary component of urban smog), and tobacco smoke (“Air Pollution” National Institute...). These emissions suspend deadly particles around in the air that can remain in the environment for long periods of time. People exposed to high levels of air pollutants may experience “burning in their eyes, an irritated throat, or breathing difficulties” (“Basic Information”). Moreover, this pollution can lead to serious, long-term health concerns including accelerated aging of the lungs, lost lung capacity, decreased lung functionality, and developed diseases such as asthma, bronchitis, emphysema, and possibly cancer (“Health Effects”). Air pollution poses a threat to the majority of Earth’s population due to the fact that the average adult breathes in 3,000 gallons of air everyday (“Basic Information”).

Major air pollutants are directly released into the atmosphere and might affect both directly or as precursor of secondary air pollutants.
Environmental pollution is the key concern for the humanity. It does not have any borders each member of our planet is affected by its devastating effects. Air pollution is the main factor contributing to general environmental problems. It is the emission of particulates, harmful materials, and biological molecules into the Earth’s atmosphere and is caused by both human and natural factors. Nevertheless, the effects of air pollution are shocking. It causes numerous diseases in human organisms, animals, natural crops, ruins the balance of the environmental system, and even causes deaths. Air pollution is the largest environmental pollution risk factor. According to the research of World Health Organization, seven million people around the world died because of the air contamination effects in 2012. This number is horrifying and calls for the extreme response. The decrease of the polluted air will help saving millions of lives. Its effects need to be discussed on a constant basis to implement the relevant prevention measures and minimize the negative.
The harm directly reflected in, if the living condition of a certain area is too bright at night, it can be difficult to sleep, disrupt the body 's normal biological clock, leading to daytime work efficiency fall, resulting in psychological stress. 2. Environmental pollution harm has two main aspects: 1. Heat island effect from the perspective of the geographical circulation of heat, because the night lighting caused unnecessary energy loss (including generating heat loss and lighting loss), is bound to increase electric effect throughout the city, thereby exacerbating urban heat island effect.
