Introduction: Air pollution can be defined as the harmful gases in the air that we breathe. Pollution can be caused by natural sources or as a result of human activities. Natural pollutants include: dust, pollen, smoke from forest fires, and bacterial and volcanic action. Nevertheless, human activities are the main cause of air pollution. Major sources of air pollution are industrial (factories and power stations) at 36% and on-road transportation at 26%. Currently, the number of vehicles on roads is constantly rising, leading to producing more pollutants. The most common pollutants in transportation are nitrogen oxides, carbon monoxide, sulpher dioxide, hydrocarbons and particulate matters. This essay will examine the impacts on human health, the environment, and even the economy that have resulted from these pollutants. It will then evaluate some of the solutions that have been put forward to reduce these harmful emissions. The increase in number of vehicles The situation is that the growth in world population, with the new styles of vehicle that were produced, is major cause of the increase in the number of vehicles worldwide. In the United States, for example, automobiles became synonymous with the free-wheeling nature of life and culture which lead a prosperous household want to have at least two cars (Mondt 2000). In Britain, another example, the number of vehicles, in 2004, rose to reach 29 million vehicles of which 24 million are private cars. Most people use their own cars in short journeys, as create unnecessary pollution. As a result, the amount of vehicle emissions increased with that growth of both population and the number of cars. Air pollution is not a recent problem and was recognized as early as 1966, accordin... ... middle of paper ... ... Works Cited Faiz, A., Weaver, C., S., and Walsh, M., P.

When we think of air pollution we think of the refineries in our cities and the exhaust coming from our cars mostly. In reality there are many more pollutants that we don't think about every day. The six most common air pollutants are; “Carbon monoxide, Nitrogen oxides, Sulphur oxides, Particulate matter, Volatile organic compounds, and Ground-level ozone (nitrogen oxide and Volatile organic compounds reaction)”(David Suzuki Foundation). The fact is people are dying from air pollution and we are doing nothing to make it better, in fact air pollution is getting worse.
Automobiles play a major role in today's society. Almost every American owns at least one motorized transportation vehicle. Some say they make our lives better by reaching places faster than before. Others say they are a harmful to the environment. Have they made our society better or worse? They may be fast, but do we as humans want our environment to suffer because of time. Face it, cars pollute. And they release destructive chemicals into the air. Air pollution can threaten the health of many subjects in the environment including human beings.
Purchasing a car is one of the hugest or biggest accomplishments that a person can achieve on their own. However, what happens when that purchase turns out to also be the worst decision that was ever made? The purchase was a success and a goal was achieved, but the moment the key is turned and the engine is started the contribution to environmental harm begins. As the car is driven, the gasoline fumes that are released from the car contribute to the other many factors and pollutants that damage the environment. Not only is the purchase now a contributor to the depletion of clean air, but it could also play a part in the depletion of someone’s health. For example, asthma or bronchitis could develop in an adult or child as a direct result of breathing in noxious automotive fumes. Depending on where one lives, there could be strict regulations on air pollution. One must be accountable for any and all contributions made to the demise of what was once a healthy Earth. One must be accountable for his or her own carbon footprint. Some individuals have taken steps to reduce their carbon footprints and cause less harm to the environment by purchasing electric cars.
Vehicles are responsible for up to eighty percent of air pollution in Mexico. There are close to four million automobiles, buses, and trucks in the city, the average of which is ten years old, and thus in poor repair with ineffective emission controls. Emissions are increased by the excessive traffic compressed into narrow streets with few parking spaces, requiring low-speed cruising (Collins, 125). Even new engines oft...
The search for a cleaner burning fuel is not a new one. Although most people know that they?re cars are spewing out toxins that are harmful to the environment, they drive the car anyway. In this modern day when faster is better, cars have become necessities. Air pollution caused by cars hasn?t always been such a big problem. When there were fewer cars on the road, nobody thought anything about the possible consequences. Not thinking ahead has always been human nature though. Environment concerns have only arisen in the past few decades because technology has allowed scientist to m...

Central idea: The involvement of technology has change the Earth’s atmosphere, it is important to understand how can air pollution in the community, and how it involves with the emissions of vehicles.
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
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,
Both of the two auto vehicles are brought into the human industry as the use of benefit students’ lives become more convenient traveler. In commons, the two automobile created opportunities jobs in the economic companies’ nation. Plus, several students did not noticed that both cars and public transportation have one major similar concept where two of the transit vehicle produce environmental pollution, traffic congestion, and oil consumption problems. Encounter, the public transportation and cars can cause a huge impact to the environmental which it can lead human health problems. Mostly, both of the automobile still release noxious gases into the air, and over time the built up can change the environment global warming to like an unhealthy
Air pollution is a type of pollution that can severely damage our environment as well as the earth’s atmosphere. Air pollution occurs all the time when the air contains many substances ...
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:
Every other day a new industries are being set up, new vehicles on roads and trees are being cut to make way for new homes. All of them, indirect way lead to increase in CO2 leads to melting of polar ice caps which increase the sea level and pose danger for the people living near coastal areas. Pollution can have an impact in our health not only affects people with impaired respiratory system such as asthmatics, but very healthy adults and children too. Exposure to pollution for 6 to 7 hours, even at relatively low concentrations, reduces lung function and induces respiratory inflammation and, healthy people during periods of moderate
The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have shown that in 1999 the worldwide number of vehicles registered was 700 million. From this huge number of vehicles, the US has a large share, which includes 200 million cars and light trucks. The number of cars worldwide also grew three times faster Competition for good things like public health, making the earth safe to live are positive aspects of competition, but global competition can also have a downside concerning the environment. This is true for the production of vehicles, as companies are coming with designs and new models with improved engines, but fuel consumption and the pollution of the air remains the same.
