Urban Living vs Suburban Living The perception of the areas we live in, are of major importance to the well being of humans because the areas we choose to live in may very well affect our lifestyle. There are pros and cons to living anywhere in the United States and the most prominent factors are suburban and urban areas. Suburban areas contain more open land, and forests which are crucial factors in our environment, whereas urban areas contain more job opportunities and opportunities for investments, which result in higher payments. The factors associated with urbanization are buildings, factories, and huge amounts of pollution, whereas suburban areas contain more farms, plantations, and crops. Researchers are still debating whether urban …show more content…
areas are “better” than rural areas. Suburban Sprawl and Urban Sprawl Urban areas, also known as suburban towns, are regions that generally surround the city. Most urbanized areas consist of little to no agriculture since urban areas are more developed, which means there are more factories, large buildings, roads, and railways. Many urban areas are called metropolitan areas, also known as "greater," such as Greater Philadelphia. Suburban areas, however, is the complete opposite; they are known as the “country side” or less developed regions. There are large amounts of agricultural land and much more space for farming (National Geographic Education). Sprawl dates back to the late 1800s when suburbs emerged outside of cities on the east coast of the United States. This occurs when people leave urbanized areas in favor of the suburbs or vice versa. Urban sprawl is the dispersion from the city into the suburbs, whereas suburban sprawl is the dispersion from the suburbs into the city (SprawlCity). There are many reasons as to why people move from urban and suburban areas such as better education, large land, and cheaper homes. In the United States, from 1950 to 1990’s, the suburban population has increased more than 200 percent, which increased the area five times its original size. The higher the population growth, the larger the area expansion will be. However, between 1999 and 2004, the percentage of the United States population living in urban areas increased from 7% to 75%. This is due to Urban sprawl can either be a great thing for a family or the downfall of the environment (Carey 564-581). Pollution Though sprawl may be driven by economic and employment, it can also be influenced by the environment.
Pollutants are contaminants that enter and affect the natural environment which can cause negative changes. There are two main types of pollution, air and water, which occur from different sources and have different effects. Air pollution is the main cause of “dirty air” in the United States. Suburban areas suffer from outdoor air pollutants as well as indoor air pollutants. Indoor air pollutants are caused by the burning of coal and wood, which are used for heating. Outdoor air pollutants are caused by chimneys, in which smoke is released into the air, and crop fertilizers, which are generally used in rural areas. The impact air pollution has on humans are large cases of health defects in rural areas: such as cancer, tuberculosis, heart diseases, and low birth weights. J.P Majra, author of “Air Quality In Rural Areas” states that, “This leads various health problems, mainly affecting the respiratory and cardiovascular system...” (Majra, 2). This shows that if the United States alone uses this much fertilizer, in which affects our health, imagine how much the world will be affected. Kirk Smith, professor of environmental health sciences at UC Berkeley’s School of Public Health states that ”nearly 10% of all lost-life years worldwide” has been due to air pollution (COEH …show more content…
2006). Water pollution can occur in many ways; the main reasons for water pollution are storm water and runoff in urban areas. Many factories were built near areas with a body of water in order for waste to be easily discharged. Sediment concentrations in urban runoff are also problematic due to increased erosion of previous construction and sediment. This affects lakes, rivers, and even ground water. Lost of water clarity, and even danger the aquatic animals and their habitats are the effects of water pollution. Urban runoff may also cause bodies of water to deplete oxygen levels in water, which can cause the death of fish and excessive odors. This affects humans because we get our drinking water from these nearby rivers and lakes. Although suburban areas contain less industrialization, they tend to have a higher percentage of water pollution than urban areas. Mining, logging, and managing crops, in rural areas can also impact water quality. Agricultural sources such as fertilizers and chemicals can interfere with water quality. Fertilizer and pesticides are used for rapid growth of vegetation and a way to keep insects from eating the food that is supposed to grow. These chemicals will eventually percolate through the soil, contaminating the groundwater and pose a threat to human health. Pollution has been an uncontrollable factor in our environment with nearly fifty percent of Americans living in polluted areas (APEC WATER). Health Urban areas contain people with a lower socioeconomic status, who are less likely to have health insurance. For this reason, these minorities face the disadvantages of quality care and disproportionate use of emergency systems. Another commonly represented population in cities are undocumented immigrants and transient populations. The higher percentage, which is currently 16%, of individuals without health insurance creates a strain on health systems (The Uninsured in Texas 2014). This often leads to differences in health care privileges, as well as a double healthcare system where insured individuals have access to routine health care, whereas transient only have access to “safety-net” emergency room care. But because urban areas are much smaller and close together, it makes traveling to medical offices easier. There are also many more options in urban areas because they are much more developed. Suburban residents have limited access to health care and they require more effort by primary care physicians. In underdeveloped areas, many suburban individuals travel long distances for primary medical care. Furthermore, some rural areas have a higher proportion of uninsured and individually insured residents than urban areas (Kletke 261-169). According to Rural Health Web, in the United States approximately 90% of physicians are located in urban areas, while the other 10% occupies suburban areas. This creates difficulty in having substantial healthcare because they do not have enough physicians, which forces them to travel a greater distance to find one. Constant trends of overweight and obesity have inspired researchers to focus on the construction of these areas and the amount of physical activity that is involved.
An article published by the Journal of Rural Health established that 40% of adults living in rural areas are obese compared to the 33% of adults living in urban areas due to the design and formation of urban and suburban areas. Many features of suburban development, such as the lack of street connectivity and the lack of sidewalks are associated with decreased physical activity. An assistant professor of preventive medicine and public health of the University of Kansas Medical Center, Christie Befort, states that "Access is often about travel time in a rural area, but it can also be that there's no place to go -- literal physical isolation.” The lack of community parks results in a drastic difference of physical activity between suburban and urban residents. All community recreational centers are resources for physical activity while also being publicly provided. Urban areas contain more parks than suburban areas, though most are unused. In 2005, a total of 6,545 park visitors were observed and results show that rural parks had more frequent visits, though they were less active. The differences suggest that findings from park and physical activity studies in urban areas should not be considered representative of their rural
counterparts. An experiment that was conducted in Turkey by EUROFIT, observed the physical health of 98 rural children and 74 suburban children. Results revealed that children in suburban areas were very active and preferred to play sports, unlike urban children who prefered to play video games. 35% of urban children were not involved in any physical activities, while suburban children had a percentage of 30. This experiment also calculated the amount of television that were watched by the children. Urban children watched a total of 13 hours or more television per week. So because of how inactive urban children were, this resulted in higher body mass and thicker skinfolds. In contrary to rural children, flexibility and muscle endurance were significantly higher due to the amount of physical activity (Ozdurenc 2005).
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.
Suburbanization, roots of the “American dream.” A house occupied by a man and woman and their three kids; the man is the breadwinner, and the woman is the stay-at-home wife. The husband would leave the house to go to work while the wife happily stay at home to cook, clean, and care for the kids. This was the imagine that were painted for consumers after World War II. This was how success was defined. However, at the other end of rainbow was not a pot of gold. Women were angry and frustrated from being confined in their homes all day. Furthermore, African Americans were excluded from this “picture perfect” dream when the government created “red lining” and made it impossible for people of color to get a house loan. The impact of suburban growth
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.
In the next decades, pollution is said to become one of the major causes for death in many urban cities. Pollution is
Suburban sprawl is linked to obesity and type two diabetes. This will be the first generation of children whom will have a shorter life span than that of their parents. Obese children are not physically fit and have now become morbidly obese in today’s society. This is due in part to the lack of places for children to achieve the necessary exercise they need due to safety concerns.
This study examines the association between walkability and the levels of obesity throughout Philadelphia County. A study performed by Feng, J. et al. (2010) states “individual behavioral change can occur only in a supportive environment with accessible and affordable healthy food choices and opportunities for regular physical activity.” There have been studies where patterns of land use have been connected with a wide variety of environmental and health consequences (Frank, L. et al. 2009). When examining the neighborhoods in Philadelphia County, there are clear differences within the county and what they have access to based on where they are located. Having access to food locations, recreational areas like parks or nature trails and other features gives the
Failure to maintain clean air standards is attributed to the increased health cases of cancer and pulmonary related diseases. In addition, there is the effect of acidic rain which poisons the plants consumed that also has health effects. The financial burden is borne by health insurance and other costs in fighting the effects.
Although Canadians have a good reason to become designers of their own urban future, there are many leading negative effects on the environment. In fact, most of Canada’s population growth in recent years has been concentrated on four regions: British Columbia’s Lower Mainland and southern Vancouver Island; the Edmonton-Calgary corridor; Toronto’s Golden Horseshoe region; and the Greater Montreal area. Despite the fact that there was virtually no growth in the rest of the country between 1996 and 2001, the population of these four regions (where 51 per cent of Canadians now live) grew 7.6 per cent. The rate at which land was urbanized in these regions was even greater, sometimes double or more the population growth rate. This difference between the growth rates of people and the land they occupied defines urban
Living in the City vs. Living in the Country The age-old question has plagued many, “Should I live in a city or should I live in the country?”. There are many advantages and disadvantages to choosing a lifestyle in either setting, and careful examination of all aspects is needed to make the perfect decision for you. One major issue affecting many people trying to make the decision on where to live is their quality of life in either extreme. Health, education, and transportation are three major concerns that many consider.
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...
Evo Morales stated, “Sooner or later, we will have to recognize that the Earth has rights too, to live without pollution. What mankind must know is that human beings cannot live without Mother Earth, but the planet can live without humans” (Pollution Quotes, 2013). Hence, attention must be provided to this devastating issue. Pollution is the introduction of contaminants into the natural environment that causes adverse changes (Wieman, 2013). There are numerous types of pollution, such as light, air, land, water, noise, thermal and radioactive pollution. In an article, the author highlighted that according to Richard Buckminster Fuller, “Pollution is nothing but the resources we are not harvesting, we allow them to disperse because we’ve been ignorant of their value” (Farrell, 1971, p. 52). Pollution is created mostly by human actions, but can also be a result of natural disasters. Pollution can harm the environment of the world and its inhabitants in many ways. Pollution has a detrimental effect on any living organism in an environment, making it virtually impossible to sustain life (Enclyopedia - Pollution, 2008).
Imagine having to choose to reside in one place for the rest of your life. Which would you opt for? Some people would argue that the hyperactive lifestyle that a big city has to offer has more benefits than living in the country. However, others would contend that the calm and peaceful environment of the countryside is much more rewarding. Several people move from the city to a farm to get away from the hustle and bustle. Likewise, some farmers have traded in their tractors and animals to live a fast paced city life. Of course, not all large cities are the same nor are all of the places in the country identical. Realizing this, ten years ago, I decided to hang up the city life in Indiana to pursue a more laid back approach to life in rural Tennessee. Certainly, city life and life in the country have their benefits, but they also have distinguishable differences.
Environmental quality can directly affect health and plays a major role in quality of life. Poor air quality is linked to long-term damage to respiratory and cardiovascular systems as well as other diseases like lung cancers (Healthy People, 2020, 2016). Safe air, land and water are fundamental human rights that contribute to a healthy community environment. A harm free environment helps prevent disease and other heath problems. A major area of concern in threatened environmental quality is indoor and outdoor air pollution. The enforcement of environmental standards and regulations to monitor pollution, human exposures and building healthy environments can improve the health and quality of life for Americans at risk (Healthy People, 2020, 2016).
It is common knowledge that humans cause pollution. As the world’s population increases so does the amount of pollution entering into the atmosphere. More people are
Pollution is so harmful to human beings. Polluted water can cause many kinds of diseases, such as diarrhea, enteritis, and so on. And sometimes the diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They will cause runs in stockings and crack rubber tires and they always eat away at stone and rust iron. Time and time again, there are serious accidents that polluted the air. For example, At 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by that accident. In 1984 there was an accident at a factory in India and a dangerous cloud gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds and thousands of people were injured. Many of the injured lost their sight, and it really dangerous, even in our imagination.
