1. Factory emissions: One of South Africa’s oldest steel manufacturers, Acelormittal (formerly known as Eskor), is situated just outside of Sharpeville. These factory chimneys protrude high into the air, so even though they give off the most air pollution (through fossil fuel emissions) and in turn lead, they are not the biggest contributor to the health issues people are developing from the air pollution, because they are above our breathing level, but it remains a contributor because as the gases are released from the chimneys the wind blows them away from the factories, the air condensates and the pollution combines with the rain to form acid rain, this cycle is demonstrated by figure 4. Acelormittal emits mostly steam and not smoke. Steam occurs when water is heated and changes to the gaseous stage, whereas smoke is a by-product of combustion and made out of particles and green-house gases such as carbon dioxide and it contains small particles such as lead (A.Helmenstine, 2014). Another big contributor is the factories in Sasolburg. Sasolburg is only 22 minutes’ drive away from Sharpeville, in this area the people experience westerly winds, so when the winds come from Sasolburg’s side, which is west of Sharpeville (Focus geography gr 12, pg 73), into Sharpeville it blows all the pollution into Sharpeville. The pollution lies heavy in the air blocking out the sun and being breathed in by all the people living in Sharpeville. The gas cycle also occurs, so the smoke which Sasols factories give off carry a lot of small particles such as lead to the area, which settles in the rivers and land. 2. Coal Stoves: Coal stoves are used to cook food and to bring warmth in the winter. Services aren’t very good in Sharpeville, so a lot of ... ... middle of paper ... ...partheid and I think they are right. The massacre was reported all over the world and it mobilised the world to start taking action about the situation in South Africa. There are also other Centripetal forces keeping the people in Sharpeville. One of these is the employment opportunities, Sharpeville was originally only hostels for mine workers to stay in while they were working in the mines, but of course with every miner came a family and so the town grew. Another centripetal force is the historical value and all the family members that still stay in the area. In 2004 a lot of people were also given their land back and were compensated for the loss of their properties and land. Of course there are also centrifugal forces in play here and that would be the air pollution of course, the health risks associated with living there and the lack of services in the area.
from solid or not. He is going to conduct an experiment that will tell him if
In recent years, the air pollution problems in China is becoming a frequent visitor of the trending topic list. Not only the air, the environment pollution is coming to hunt humans down in many different ways. It’s in the air, earth, water and even larger scale like the global warming. I know it is controversial regarding the global warming issue. Many big figure, Donald Trump for example, denies global warming as a problem we should pay attention to. However, I myself is a believer of such theory and I think we should act before it is too late. Regardless of global warming being real or not, it is better for us to act than doing nothing since the potential hazard could be catastrophic to the entire human race.
One of the most dangerous environment issues Southern California is facing today is air pollution. This includes the burning of fossil fuels and natural disasters. Los Angeles is one of the most polluted cities in the world, and the most polluted city in the United States. I will research information about the causes, the effects, and the history of air pollution in the Los Angeles. For my research, I have relied mostly on, the school’s database and library, as well as current events.
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Air pollution is caused by many things such as car fumes, burning of fossil fuels,

Our planet is suffering from severe pollution, which ranges from contaminated air, water and soil as well. Humans are doing nothing to reduce the amount of pollution that is harming our earth. To understand how pollution works first you must understand that there are different types of pollution. The most common types of pollution and the ones that I will be focusing on which are the ones doing the most harm to our planet are air pollution, water pollution, soil contamination and littering. In order to help out and reduce pollution in our planet people need to be more aware of what these problems are and about the severe damages that they are causing our planet. Before industrialization really jumped into place and had an effect on large cities, nature had its own way of cleaning up its own air and itself. Wind scattered gases, rain washed many substances and the rest dissolved into the ground; while plants absorbed carbon dioxide and made it into oxygen. With big cities growing more every time and with more towns that were becoming more industrialized a lot of more waste began to be released into the environment and the atmosphere and soon this was more than enough for nature to handle. In order to stop and reduce pollution people need to understand the damage that it is causing our environment and our planet as well. People need to be more aware of how they can help out and do their part in reducing these problems that are causing our planet to die slowly with people not even noticing it.
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
The environment and health are very closely linked. The environment in which we inhabit and go about our daily lives, directly impacts on our physical, mental and social well-being. There are biological, chemical and physical factors that can affect human health in a physical and mental way. The World Health Organisation states that "health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity" (WHO 1948), meaning that although many factors relating to health are associated with environmental pollution, they can also be caused by the environment in which we work and live in. The relationship between the environment and health, can however be quite complex. Human health is not only as a result of air, water and ground pollution, but also things such as food, genetics, life style and quality, which directly affect human susceptibility to illness, disease and possibly death. Disruptions to the environment, such as substance dispersal, climate change, acidification, ground pollution, photochemical air pollution and over fertilisation can also impact on human health. Therefore, there are direct and indirect links to the environment and health issues.
Air is an important aspect of our lives that allows us to live on the planet Earth. Without air, we could not survive. As humans, we rely on air to survive, so the quality of our air should also be important to us. “Adults breathe in about 10-20 cubic meters of air everyday. That is about twenty-thousand breaths. Children breathe almost twice that amount…” (B.C. Air Quality). Air has so much to do with the health and survival of many living organisms on this planet. Therefore, in this paper, we will talk about the chemistry behind air quality, what effects air quality in our environment, but more importantly how we can improve air quality itself to make the planet a much more greener place.
Air Pollution is when a poisonous or a harmful substance is released in the air. There are many form of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air.Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that need the atmosphere is air pollution.Humans have been undergoing air pollution ever since the industrial revolution.In order to understand the causes of Air pollution, it is divided into divisions. Primary air pollutants and secondary air pollutants:
The environmental issue that I’ve chosen is air pollution. Air Pollution is a huge environmental issue not only in the United States but all over the world. I picked this issue because of the affect that it has on our entire world. This is a highly important issue that people should be aware of because of the huge effect it has on practically everyone. In my essay I will address what air pollution is and how it starts, I will talk about which cities have high pollution verses cities with low pollution, what’s being done to change, and the affect it has on humans, animals, and our earth.
What is pollution? Pollution is a detrimental enemy to all species that walk on earth. It is a product of mankind carbon foot print on the environment. It consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. Pollution occurs when pollutants contaminate the natural surrounding; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements of pollution which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance in the environment. With innovation and development in our lives pollution has reached its peaks; giving rise to global warming and human illness. When raw materials, water, energy and other resources
Today talking about environmental issues lately to be like a common topic discussion until people take it for granted. However, the world facing a complex environmental problems related to each trouble that connected to one another and come out with greater impacts to the environment and humans. This is because the effects of environmental only can be seen in long term period rather than immediately result show up. Environmental issues must become one of the controversial matters in the society in order to make people know the truth what the world currently facing. There were a lot of environmental disaster happened such as climate change, global warming, various of pollutions, earthquake and etc. the rise of environmental issues begin with this urban development occur through several countries following with the technologies equip along. For sure, development will cause a huge negative impact to the environment if it deals without a care. Besides, the environment is the place in the ecosystem to hold and use in finding resources to continuously survive in this world. Thus, the finding and digging for the resources which happening extensively without preservation will not restore the surrounding similar with before. But then, the change cannot be refuse and people need to take an action to save the threaten the world and the ecosystem from being extinct. If each country has own output in causing an environmental problem, then consider the world to hold all the damage occurred. Exposing the effects of environmental issues throughout the world, make people realize the important to take care the environment.
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
