Introduction
Air pollution is continuously deteriorating and influences the livability of society in Hong Kong. Thus, it is necessary to find some suggestions to control air pollution. Air pollution is a real public health and the environmental problem which consists of air pollutants such as carbon monoxide, volatile organic compounds, ozone, nitrogen dioxide, sulphur dioxide, and fine and coarse particles. According to Environmental Protection Department (2016), Hong Kong is facing with two main air pollution issues: local street-level pollution and regional smog problem. EPD (2016) describes that the level of air pollutant in Hong Kong was 3.6 times higher than the World Health Organization recommended acceptable level. The mortality rate

It contains harmful particles. If people breathe them into lungs, people will feel uncomfortable and even suffer from lungs disease leading to visit public hospitals and hence increase the government’s medical burden. A research by WHO (2016) estimates that there are nearly 70% outdoor air pollution-related premature deaths because of ischaemic heart disease and strokes, while nearly 14% outdoor air pollution-related premature deaths are due to chronic obstructive pulmonary disease or acute lower respiratory infection, and about 14% outdoor air pollution-related premature deaths are due to lung cancer. In the past few years, Hong Kong Air Quality Objective has been worse due to the increase of the level of respirable suspended particulates and nitrogen dioxide at the roadside (EPD, 2016). Kampa and Castanas (2008) illustrates that air pollutant causes increasing mortality and hospital admissions. Owing to poor air quality, people would feel hard to breathe and if they stay at the roadside for a long time, they may feel uncomfortable, even suffer from skin or respiratory irritation. The Chinese University of Hong Kong (2013) reports that Hong Kong may be required to invest extra $3.8 billion annually in medical expenses and productivity due to air pollution in the future. Therefore, air pollution not only could harm human health but also increase the government’s medical
Many people are unknowingly exposed to air pollution and have no idea. Some common causes of air pollution are automobiles, factories, landfills and toxic materials. Air pollution destroys the environment; it causes climate change because it greatly affects the greenhouse effect and it causes acid rain. Acid rain contaminates water and destroys animal’s homes. Air pollution has many effects on people it causes coughing, elevates your risk of asthma, wheezing, it can cause diseases and birth defects. It’s estimated “that seven million people died prematurely in 2012 from exposure to air pollution and that air pollution can cause cardiovascular diseases. The use of incinerators has caused protest movements from the Chinese citizens because they are becoming aware of the air pollution that is being given off from the burning of their trash and the effects it has on their health. There have been many reports of premature births and stillbirths of pregnant women that live near garbage incinerators”( Professional Safety, 2014, p.
One afternoon, Kendra Bishop, a fifteen year old teen from Manhattan, New York, receives several knocks on her door. Eager to open it, she breaks rule number one- never open the door to strangers. A bright light illuminates her vision and the voice of a lady pierces her ear. Making their way in, the camera crew has all lights on Kendra and her home. The lady congratulates her on becoming the new Black Sheep.
Imagine living in a smog, pollution free environment where the air was clean and skies were clear. Unfortunately, we do not have this luxury of that reality in the Central Valley. As many are aware, the Central Valley has a reputation of being one of the most polluted areas in California. With the air so polluted, it makes living in the Central Valley a little more difficult for everyone, whether it is realized or not. Although there are many reasons that cause the air to be polluted, the air in the Central Valley is polluted mainly because of the large manufacture infrastructures, semi/diesel trucks, fireplaces, and farming. Indeed, there are many reasons for air pollution, but let’s move on to the first reason.
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.
More than three million children under the age of five have passed away because of pollution and other environmental factors (Rinkesh). Pollution is the leading cause of death among developing countries (Petru, Alexis). Air pollution analyst and environmental chemist are two careers that focus on improving our environment to make it safer to live in.
Although ambient air pollution has decreased over the past several decades due to stringent air pollution control policies, there has been little evidence directly supporting the extent these control measures have improved public health (Tonne, et al, 2010). Investigative research has observed evidence to support the association of air pollution and particulate matter with increased cardiovascular events.
In an era of rising technology and increasing population, demands on the environment are continually being pushed to new levels. As a result, it becomes important for us to expand our knowledge about the environment and take appropriate actions to protect this element of most importance to human existence. One component of our environment experiencing some of the greatest abuse due to humans is the air. Air pollution has been on the rise ever since the beginning of industrialization. The climbing number of factories and use of cars worldwide are the major culprits of this environmental hazard. There are various gases released into the air that can be considered air pollutants, but one of the most prevalent and dangerous to the environment is carbon dioxide (CO2). Up to 95% of the CO2 produced is the result of natural processes (Burnett & Matthews Jr., 1998). The rest is a direct result of human activity, primarily through the burning of fossil fuels in the production of energy
As a country with more people, there are assumably more cars, meaning more gases will be emitted that harm the environment. However, if a rapidly growing population stopped growing as quickly, there would be less people to need cars, which reduces pollution. The vice director of Population Commission in Henan says that the population being controlled “have kept sulfur dioxide emissions down by 17.6%” and “[reduced] water pollution 30.8%” (Document C). With such a significant decrease, less people were being diagnosed with pollution related illnesses. Sulfur Dioxide, a gas that is emitted from cars, “is a major cause of asthma and bronchial infection” (Document C), and with less Sulfur Dioxide in the air, people can have a healthier life.
Air pollution affects both New York’s environment and people. Emissions from industry, power plants, and vehicles are released into the atmosphere, causing smog, photochemical smog, particulate matter, ground level ozone, and acid rain. Air pollutants lead to respiratory problems in humans, and increase the severity in those who already have respiratory system related illnesses. Acid precipitation damages buildings, cars, trees, and crops, which can cause quite a financial burden – this is especially concerning when it comes to preserving New York City’s many historic buildings. Air pollution also contributes towards global warming which causes a change in the Earth’s climate. Drastic actions need to be put in motion in order for the issue
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.
Air Pollution in Mexico City Mexico City adds an estimated one million new residents each year, resulting in one million new additions to the city’s already abominable air quality (Collins, 119). Over the span of a generation, Mexico City’s air has gone from being one of the world’s cleanest to one of the world’s most polluted, as well as the most polluted in its country. The average visibility in the city is down from almost 100 km in the 1940s to only 1.5 km today, removing the once beautiful landscape of the surrounding snow-capped volcanoes (Yip, 1). More significantly, however, Mexico City’s air problems have resulted in a notable decrease in the health of its residents, particularly its children. There are a variety of reasons for the decline in air quality, including factory emissions, suspended particles, vehicles, as well as problematic geographic hindrances.
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.
Many cities are currently affected by air pollution and Hong Kong is one example. Hong Kong’s air pollution level often exceeds the recommended air pollution level put out by the World Health Organization, and Hong Kong’s pollution index was at “very high” meaning that it exceeded 101, for 34% of the time (Hunt, 2011). Another example, when Hong Kong excee...
Air pollution has become very costly environmental problem in terms of both human lives and in terms of billions of dollars lost for health-care expenditure and crop damage.
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
