Introduction to Population, Urbanization, and the Environment
Environmental Racism
Environmental racism refers to the way in which minority group neighborhoods (populated primarily by people of color and members of low socioeconomic groups) are burdened with a disproportionate number of hazards, including toxic waste facilities, garbage dumps, and other sources of environmental pollution and foul odors that lower the quality of life. All around the globe, members of minority groups bear a greater burden of the health problems that result from higher exposure to waste and pollution. This can occur due to unsafe or unhealthy work conditions where no regulations exist (or are enforced) for poor workers, or in neighborhoods that are uncomfortably close to toxic materials.
cancer cluster
The enormous oil disaster that hit the Louisiana Gulf Coast in 2010 is just one of a high number of environmental crises that have led to toxic residue. They include the pollution of the Love Canal neighborhood of the 1970s to the Exxon Valdez oil tanker crash of 1989, the Chernobyl disaster of 1986, and Japan's Fukushima nuclear plant incident following the earthquake in 2011. Often, the stories are not newsmakers, but simply an unpleasant part of life for the people who live near toxic sites such as Centralia, Pennsylvania and Hinkley, California. In many cases, people in these neighborhoods can be part of a cancer cluster without realizing the cause.
Mortality Rate
A measure of the number of people in a population who die.
Cancer Cluster
A geographic area with high levels of cancer within its population.
Emergent Norm Theory
A perspective that emphasizes the importance of social norms in crowd behavior.
Urbanization around the World
During the Industrial Era, there was a growth spurt worldwide. The development of factories brought people from rural to urban areas, and new technology increased the efficiency of transportation, food production, and food preservation. For example, from the mid-1670s to the early 1900s, London's population increased from 550,000 to 7 million (Old Bailey Proceedings Online 2011). Global favorites like New York, London, and Tokyo are all examples of postindustrial cities. As cities evolve from manufacturing-based industrial to service- and information-based postindustrial societies, gentrification becomes more common.
Gentrification
Gentrification occurs when members of the middle and upper classes enter and renovate city areas that have been historically less affluent while the poor urban underclass are forced by resulting price pressures to leave those neighborhoods for increasingly decaying portions of the city.
The Air is Polluting & We Take Oxygen for Granted
Much of the pollution in the air comes from human activity. How many college students move their cars across campus at least once a day? Who checks the environmental report card on how many pollutants each company throws into the air before purchasing a cell phone? Many of us are guilty of taking our environment for granted without concern for how everyday decisions add up to a long-term global problem. How many minor adjustments can you think of, like walking instead of driving, that would reduce your overall carbon footprint?
Social Movements OWS
Perhaps the social movement that ran the most contrary to theory in recent history is Occupy Wall Street (OWS). Although it contains many of the classic developmental elements of a social movement we will describe in this chapter, it is set apart by its lack of a single message, its leaderless organization, and its target—financial institutions instead of the government. OWS baffled much of the public, and certainly the mainstream media, leading many to ask, "Who are they, and what do they want?"
Daddy Joe Wanted to Ban Fracking
As you read this chapter, consider how an increasing global population can balance environmental concerns with opportunities for industrial and economic growth. Think about how much water pollution can be justified by the need to lower U.S. dependence of foreign energy supplies. Is the potential employment and economic growth associated with fracking worth some environmental degradation?
Conflict Theorist
A conflict theorist, interested in the creation and reproduction of inequality, might ask how peripheral nations' lack of family planning affects their overall population in comparison to core nations that tend to have lower fertility rates. Or, how do inner cities become ghettos, nearly devoid of jobs, education, and other opportunities? A conflict theorist might also study environmental racism and other forms of environmental inequality. For example, which parts of New Orleans society were the most responsive to the evacuation order during Hurricane Katrina? Which area was most affected by the flooding? And where (and in what conditions) were people from those areas housed, both during and before the evacuation?
Zero Population Growth
A neo-Malthusian researcher named Paul Ehrlich brought Malthus's predictions into the twentieth century. However, according to Ehrlich, it is the environment, not specifically the food supply, that will play a crucial role in the continued health of planet's population (Ehrlich 1968). Ehrlich's ideas suggest that the human population is moving rapidly toward complete environmental collapse, as privileged people use up or pollute a number of environmental resources such as water and air. He advocated for a goal of zero population growth (ZPG), in which the number of people entering a population through birth or immigration is equal to the number of people leaving it via death or emigration. While support for this concept is mixed, it is still considered a possible solution to global overpopulation.
Symbolic Interactionist
A symbolic interactionist interested in the day-to-day interaction of groups and individuals might research topics like the way family-planning information is presented to and understood by different population groups, the way people experience and understand urban life, and the language people use to convince others of the presence (or absence) of global climate change. For example, some politicians wish to present the study of global warming as junk science, and other politicians insist it is a proven fact.
Demographic Transition Theory
A theory that describes four stages of population growth, following patterns that connect birth and death rates with stages of industrial development.
Resource Mobilization Theory
A theory that explains social movements' success in terms of their ability to acquire resources and mobilize individuals.
The Growth of Cities
According to sociologist Gideon Sjoberg (1965), there are three prerequisites for the development of a city: First, good environment with fresh water and a favorable climate; second, advanced technology, which will produce a food surplus to support nonfarmers; and third, strong social organization to ensure social stability and a stable economy. Most scholars agree that the first cities were developed somewhere in ancient Mesopotamia, though there are disagreements about exactly where. Most early cities were small by today's standards, and the largest was most likely Rome, with about 650,000 inhabitants (Chandler and Fox, 1974). The factors limiting the size of ancient cities included lack of adequate sewage control, limited food supply, and immigration restrictions. For example, serfs were tied to the land, and transportation was limited and inefficient. Today, the primary influence on cities' growth is economic forces. Since the recent economic recession reduced housing prices, researchers have been waiting to see what happens to urban migration patterns in response.
Migration
Another key element in studying populations is the movement of people into and out of an area. Migration may take the form of immigration, which describes movement into an area to take up permanent residence, or emigration, which refers to movement out of an area to another place of permanent residence. Migration might be voluntary (as when college students study abroad), involuntary (as when Syrians evacuated war-torn areas), or forced (as when many Native American tribes were removed from the lands they'd lived in for generations).
Poison in Water & Food
As a consequence of population concentrations, water close to human settlements is frequently polluted with untreated or partially treated human waste (sewage), chemicals, radioactivity, and levels of heat sufficient to create large "dead zones" incapable of supporting aquatic life. The methods of food production used by many core nations rely on liberal doses of nitrogen and pesticides, which end up back in the water supply. In some cases, water pollution affects the quality of the aquatic life consumed by water and land animals. As we move along the food chain, the pollutants travel from prey to predator. Since humans consume at all levels of the food chain, we ultimately consume the carcinogens, such as mercury, accumulated through several branches of the food web.
Suburbs
As cities grew more crowded, and often more impoverished and costly, more and more people began to migrate back out of them. But instead of returning to rural small towns (like they'd resided in before moving to the city), these people needed close access to the cities for their jobs. In the 1850s, as the urban population greatly expanded and transportation options improved, suburbs developed. Suburbs are the communities surrounding cities, typically close enough for a daily commute in, but far enough away to allow for more space than city living affords. The bucolic suburban landscape of the early twentieth century has largely disappeared due to sprawl. Suburban sprawl contributes to traffic congestion, which in turn contributes to commuting time. And commuting times and distances have continued to increase as new suburbs developed farther and farther from city centers. Simultaneously, this dynamic contributed to an exponential increase in natural resource use, like petroleum, which sequentially increased pollution in the form of carbon emissions.
Our Relationship with the Environment
As the discussion of fracking illustrates, there are important societal issues connected to the environment and how and where people live. Sociologists begin to examine these issues through demography, or the study of population and how it relates to urbanization, the study of the social, political, and economic relationships in cities. Environmental sociologists look at the study of how humans interact with their environments. Today, as has been the case many times in history, we are at a point of conflict in a number of these areas. The world's population reached seven billion between 2011 and 2012. When will it reach eight billion? Can our planet sustain such a population? We generate more trash than ever, from Starbucks cups to obsolete cell phones containing toxic chemicals to food waste that could be composted. You may be unaware of where your trash ends up. And while this problem exists worldwide, trash issues are often more acute in urban areas. Cities and city living create new challenges for both society and the environment that make interactions between people and places of critical importance.
exurbs
As the suburbs became more crowded and lost their charm, those who could afford it turned to the exurbs, communities that exist outside the ring of suburbs, and are typically populated by even wealthier families who want more space and have the resources to lengthen their commute.
Demography and Population
Between 2011 and 2012, we reached a population milestone of 7 billion humans on the earth's surface. The rapidity with which this happened demonstrated an exponential increase from the time it took to grow from 5 billion to 6 billion people. In short, the planet is filling up. How quickly will we go from 7 billion to 8 billion? How will that population be distributed? Where is population the highest? Where is it slowing down? Where will people live? To explore these questions, we turn to demography, or the study of populations. Three of the most important components that affect the issues above are fertility, mortality, and migration.
Population Growth
Changing fertility, mortality, and migration rates make up the total population composition, a snapshot of the demographic profile of a population. This number can be measured for societies, nations, world regions, or other groups. The population composition includes the sex ratio, the number of men for every hundred women, as well as the population pyramid, a picture of population distribution by sex and age (Figure).
Air
China's fast-growing economy and burgeoning industry have translated into notoriously poor air quality. Smog hangs heavily over the major cities, sometimes grounding aircraft that cannot navigate through it. Pedestrians and cyclists wear air-filter masks to protect themselves. In Beijing, citizens are skeptical that the government-issued daily pollution ratings are trustworthy. Increasingly, they are taking their own pollution measurements in the hopes that accurate information will galvanize others to action. Given that some days they can barely see down the street, they hope action comes soon (Papenfuss, 2011). Humanity, with its growing numbers, use of fossil fuels, and increasingly urbanized society, is putting too much stress on the earth's atmosphere. The amount of air pollution varies from locale to locale, and you may be more personally affected than you realize. How often do you check air quality reports before leaving your house? Depending on where you live, this question can sound utterly strange or like an everyday matter. Along with oxygen, most of the time we are also breathing in soot, hydrocarbons, carbon, nitrogen, and sulfur oxides.
Strain in Society
Cities provide numerous opportunities for their residents and offer significant benefits including access to goods to numerous job opportunities. At the same time, high population areas can lead to tensions between demographic groups, as well as environmental strain. While the population of urban dwellers is continuing to rise, sources of social strain are rising along with it. The ultimate challenge for today's urbanites is finding an equitable way to share the city's resources while reducing the pollution and energy use that negatively impacts the environment.
Social Change
Continuing in the lesson, our final topics will address collective behavior, social movements and social change. Emergent norm, value-added, and assembling perspective analyses of collective behavior will be discussed as we learn about stages and different types of social movements. Theoretical perspectives on social movements, such as resource mobilization, framing, and new social movement theory will be applied to add another dimension in our understanding. Lesson 11 will conclude with a discussion on the importance of modernization and the role of technology on bringing about social change.
Sustainable Development
Development that occurs without depleting or damaging the natural environment.
Fracking
Fracking, another word for hydraulic fracturing, is a method used to recover gas and oil from shale by drilling down into the earth and directing a high-pressure mixture of water, sand, and proprietary chemicals into the rock. Commonly, this process also includes drilling horizontally into the rock to create new pathways for gas to travel. While energy companies view fracking as a profitable revolution in the industry, there are a number of concerns associated with the practice. First, fracking requires huge amounts of water. Water transportation comes at a high environmental cost, and once mixed with fracking chemicals, water is unsuitable for human and animal consumption, though it is estimated that between 10 percent and 90 percent of the contaminated water is returned to the water cycle. Second, the chemicals used in a fracking mix are potentially carcinogenic. These chemicals may pollute groundwater near the extraction site (Colborn, Kwiatkowski, Schultz, and Bachran, 2011; United States, 2011). Industry leaders suggest that such contamination is unlikely, and that when it does occur, it is incidental and related to unavoidable human error rather than an expected risk of the practice, but the U.S. Environmental Protection Agency's study of fracking is ongoing (Environmental Protection Agency, 2014). The third concern is that fracking may cause minor earthquakes by undermining the seismic stability of an area—a concern downplayed by the companies involved (Henry 2012). Finally, gas is not a renewable source of energy; this is a negative in the eyes of those who oppose continued reliance on fossil fuels. Fracking is not without its advantages. Its supporters offer statistics that suggest it reduces unemployment and contributes to economic growth (IHS Global Insights, 2012). Since it allows energy companies access to previously nonviable and completely untapped oil and gas reserves, fracking boosts domestic oil production and lowers energy costs (IHS Global Insights, 2012). Finally, fracking expands the production of low-emission industrial energy.
Capitalism
In contrast to the functionalist approach, theoretical models in the conflict perspective focus on the way urban areas change according to specific decisions made by political and economic leaders. These decisions generally benefit the middle and upper classes while exploiting the working and lower classes.
sustainable development
Globally, 54 percent of the world's 7 billion people currently reside in urban areas, with the most urbanized region being North America (82 percent), followed by Latin America/the Caribbean (80 percent), with Europe coming in third (72 percent). In comparison, Africa is only 40 percent urbanized. With 38 million people, Tokyo is the world's largest city by population. The world's most densely populated cities are now largely concentrated in the global south, a marked change from several decades ago when the biggest cities were found in the global north. In the next forty years, the biggest global challenge for urbanized populations, particularly in less developed countries, will be to achieve development that occurs without depleting or damaging the natural environment, also called sustainable development (United Nations, Department of Economic and Social Affairs, Population Division, 2014).
Functionalist
How do sociologists study population and urbanization issues? Functionalist sociologists might focus on the way all aspects of population, urbanization, and the environment serve as vital and cohesive elements, ensuring the continuing stability of society. They might study how the growth of the global population encourages emigration and immigration, and how emigration and immigration serve to strengthen ties between nations. Or they might research the way migration affects environmental issues; for example, how have forced migrations, and the resulting changes in a region's ability to support a new group, affected both the displaced people and the area of relocation? Another topic a functionalist might research is the way various urban neighborhoods specialize to serve cultural and financial needs.
Human ecology
Human ecology is a functionalist field of study that looks at the relationship between people and their built and natural physical environments (Park, 1915). Generally speaking, urban land use and urban population distribution occur in a predictable pattern once we understand how people relate to their living environment. For example, in the United States, we have a transportation system geared to accommodate individuals and families in the form of interstate highways built for cars. In contrast, most parts of Europe emphasize public transportation such as high-speed rail and commuter lines, as well as walking and bicycling. The challenge for a human ecologist working in U.S. urban planning is to design landscapes and waterscapes with natural beauty, while also figuring out how to provide for free-flowing transport of innumerable vehicles, not to mention parking!
MANAGING REFUGEES AND ASYLUM-SEEKERS IN THE MODERN WORLD
In 2013, the number of refugees, asylum-seekers, and internally displaced people worldwide exceeded 50 million people for the first time since the end of World War II. Half these people were children. A refugee is defined as an individual who has been forced to leave his or her country in order to escape war, persecution, or natural disaster, while asylum-seekers are those whose claim to refugee status has not been validated. An internally displaced person, on the other hand, is neither a refugee nor an asylum-seeker. Displaced persons have fled their homes while remaining inside their country's borders.
Social Media Exposing Harms of Capitalism (Bernie Sanders & AOC)
In answer to the question "Who are they?" Castells notes ". . . by and large the movement was made up of a large majority of democratic voters, as well as of politically independent minded people who were in search of new forms of changing the world . . . " (Castells, 2012). What do they want? Castells has dubbed OWS "A non-demand movement: The process is the message." Using Facebook, Twitter, Tumblr, and live-stream video, the protesters conveyed a multifold message with a long list of reforms and social change, including the need to address the rising disparity of wealth, the influence of money on election outcomes, the notion of "corporate personhood," a corporatized political system (to be replaced by "direct democracy"), political favoring of the rich, and rising student debt. Regardless, some in the media appeared confused about the protestors' intentions, and articles carried titles like, "The Wall Street Protesters: What the Hell Do They Want?" (Gell, 2011) from The New York Observer, and person-in-the-street quotations like, "I think they're idiots. They have no agenda . . . " from the Los Angeles Times (Le Tellier, 2012).
Water
Look at your watch. Wait fifteen seconds. Then wait another fifteen seconds. In that time, two children have died from lack of access to clean drinking water. Access to safe water is one of the most basic human needs, and it is woefully out of reach for millions of people on the planet. Many of the major diseases that peripheral countries battle, such as diarrhea, cholera, and typhoid, are caused by contaminated water. Often, young children are unable to go to school because they must instead walk several hours a day just to collect potable water for their family. The situation is only getting more dire as the global population increases. Water is a key resource battleground in the twenty-first century. As every child learns in school, 70 percent of earth is made of water. Despite that figure, there is a finite amount of water usable by humans and it is constantly used and reused in a sustainable water cycle. The way we use this abundant natural resource, however, renders much of it unsuitable for consumption and unable to sustain life. For instance, it takes two and a half liters of water to produce a single liter of Coca-Cola. The company and its bottlers use close to 300 billion liters of water a year, often in locales that are short of useable water (Blanchard, 2007).
Evils of Capitalism
Manuel Castells (2012) notes that the years leading up to the Occupy movement had witnessed a dizzying increase in the disparity of wealth in the United States, stemming back to the 1980s. The top 1 percent in the nation had secured 58 percent of the economic growth in the period for themselves, while real hourly wages for the average worker had increased by only 2 percent. The wealth of the top 5 percent had increased by 42 percent. The average pay of a CEO was now 350 times that of the average worker, compared to less than 50 times in 1983 (AFL-CIO, 2014). The country's leading financial institutions, to many clearly to blame for the crisis and dubbed "too big to fail," were in trouble after many poorly qualified borrowers defaulted on their mortgage loans when the loans' interest rates rose. The banks were eventually "bailed" out by the government with $700 billion of taxpayer money. According to many reports, that same year top executives and traders received large bonuses.
megalopolis
New York was the first U.S. megalopolis, a huge urban corridor encompassing multiple cities and their surrounding suburbs. These metropolises use vast quantities of natural resources and are a growing part of the U.S. landscape.
Cornucopian theory
Of course, some theories are less focused on the pessimistic hypothesis that the world's population will meet a detrimental challenge to sustaining itself. Cornucopian theory scoffs at the idea of humans wiping themselves out; it asserts that human ingenuity can resolve any environmental or social issues that develop. As an example, it points to the issue of food supply. If we need more food, the theory contends, agricultural scientists will figure out how to grow it, as they have already been doing for centuries. After all, in this perspective, human ingenuity has been up to the task for thousands of years and there is no reason for that pattern not to continue (Simon 1981).
Pollution
Pollution describes what happens when contaminants are introduced into an environment (water, air, land) at levels that are damaging. Environments can often sustain a limited amount of contaminants without marked change, and water, air, and soil can "heal" themselves to a certain degree. However, once contaminant levels reach a certain point, the results can be catastrophic.
Toxic and Radioactive Waste
Radioactivity is a form of air pollution. While nuclear energy promises a safe and abundant power source, increasingly it is looked upon as a danger to the environment and to those who inhabit it. We accumulate nuclear waste, which we must then keep track of long term and ultimately figure out how to store the toxic waste material without damaging the environment or putting future generations at risk. The 2011 earthquake in Japan illustrates the dangers of even safe, government-monitored nuclear energy. When disaster occurs, how can we safely evacuate the large numbers of affected people? Indeed, how can we even be sure how far the evacuation radius should extend? Radiation can also enter the food chain, causing damage from the bottom (phytoplankton and microscopic soil organisms) all the way to the top. Once again, the price paid for cheap power is much greater than what we see on the electric bill.
Growing Populations
Scholars understand demography through various analyses. Malthusian, zero population growth, cornucopian theory, and demographic transition theories all help sociologists study demography. The earth's human population is growing quickly, especially in peripheral countries. Factors that impact population include birthrates, mortality rates, and migration, including immigration and emigration. There are numerous potential outcomes of the growing population, and sociological perspectives vary on the potential effect of these increased numbers. The growth will pressure the already taxed planet and its natural resources.
Politics & Climate Change
So why is there a controversy? The National Oceanographic and Atmospheric Association (NOAA) recognizes the existence of climate change. So do nearly 200 countries that signed the Kyoto Protocol, a document intended to engage countries in voluntary actions to limit the activity that leads to climate change. (The United States was not one of the 200 nations committed to this initiative to reduce environmental damage, and its refusal to sign continues to be a source of contention.) What's the argument about? For one thing, for companies making billions of dollars in the production of goods and services, the idea of costly regulations that would require expensive operational upgrades has been a source of great anxiety. They argue via lobbyists that such regulations would be disastrous for the economy. Some go so far as to question the science used as evidence. There is also a lot of finger-pointing among countries, especially when the issue arises of who will be permitted to pollute.
Demographic Theories
Sociologists have long looked at population issues as central to understanding human interactions. Below we will look at four theories about population that inform sociological thought: Malthusian, zero population growth, cornucopian, and demographic transition theories.
Human Activity Destroying Earth
The area of environmental sociology is growing as extreme weather patterns and concerns over climate change increase. Human activity leads to pollution of soil, water, and air, compromising the health of the entire food chain. While everyone is at risk, poor and disadvantaged neighborhoods and nations bear a greater burden of the planet's pollution, a dynamic known as environmental racism.
concentric zone model
The concentric zone model (Burgess, 1925) is perhaps the most famous example of human ecology. This model views a city as a series of concentric circular areas, expanding outward from the center of the city, with various "zones" invading adjacent zones (as new categories of people and businesses overrun the edges of nearby zones) and succeeding (then after invasion, the new inhabitants repurpose the areas they have invaded and push out the previous inhabitants). In this model, Zone A, in the heart of the city, is the center of the business and cultural district. Zone B, the concentric circle surrounding the city center, is composed of formerly wealthy homes split into cheap apartments for new immigrant populations; this zone also houses small manufacturers, pawn shops, and other marginal businesses. Zone C consists of the homes of the working class and established ethnic enclaves. Zone D holds wealthy homes, white-collar workers, and shopping centers. Zone E contains the estates of the upper class (in the exurbs) and the suburbs.
Fertility vs. Mortality
The fertility rate of a society is a measure noting the number of children born. The fertility number is generally lower than the fecundity number, which measures the potential number of children that could be born to women of childbearing age. Sociologists measure fertility using the crude birthrate (the number of live births per 1,000 people per year). Just as fertility measures childbearing, the mortality rate is a measure of the number of people who die. The crude death rate is a number derived from the number of deaths per 1,000 people per year. When analyzed together, fertility and mortality rates help researchers understand the overall growth occurring in a population.
USA Climate Change initiatives
The international community continues to work toward a way to manage climate change. During the 2009 United Nations Climate Change Conference in Copenhagen, the United States agreed to fund global climate change programs. In September 2010, President Obama announced the Global Climate Change Initiative (GCCI) as part of his administration's Global Development Policy. The GCCI is a United States Agency for International Development (USAID) funding program intended to improve the economic and environmental sustainability of peripheral and semi-peripheral countries by encouraging the use of alternative, low-carbon, energy sources with financial incentives. Programming is organized around three pillars: (1) climate change adaptation, (2) clean energy, and (3) sustainable landscapes (Troilo, 2012).
Theoretical Perspectives on Urbanization
The issues of urbanization play significant roles in the study of sociology. Race, economics, and human behavior intersect in cities. Let's look at urbanization through the sociological perspectives of functionalism and conflict theory. Functional perspectives on urbanization generally focus on the ecology of the city, while conflict perspective tends to focus on political economy.
White Flight
The migration of economically secure white people from racially mixed urban areas toward the suburbs. As the Social Policy & Debate feature illustrates, the suburbs also have their share of socio-economic problems. In the United States, white flight refers to the migration of economically secure white people from racially mixed urban areas and toward the suburbs. This occurred throughout the twentieth century, due to causes as diverse as the legal end of racial segregation established by Brown v. Board of Education to the Mariel boatlift of Cubans fleeing Cuba's Mariel port for Miami. Current trends include middle-class African-American families following white flight patterns out of cities, while affluent whites return to cities that have historically had a black majority. The result is that the issues of race, socio-economics, neighborhoods, and communities remain complicated and challenging.
Environmental Racism on Black Kids
The statistics on environmental racism are shocking. Research shows that it pervades all aspects of African Americans' lives: environmentally unsound housing, schools with asbestos problems, facilities and playgrounds with lead paint. A twenty-year comparative study led by sociologist Robert Bullard determined "race to be more important than socioeconomic status in predicting the location of the nation's commercial hazardous waste facilities" (Bullard et al. 2007). His research found, for example, that African American children are five times more likely to have lead poisoning (the leading environmental health threat for children) than their Caucasian counterparts, and that a disproportionate number of people of color reside in areas with hazardous waste facilities (Bullard et al. 2007). Sociologists with the project are examining how environmental racism is addressed in the long-term cleanup of the environmental disasters caused by Hurricane Katrina.
The Environment and Society
The subfield of environmental sociology studies the way humans interact with their environments. This field is closely related to human ecology, which focuses on the relationship between people and their built and natural environment. This is an area that is garnering more attention as extreme weather patterns and policy battles over climate change dominate the news. A key factor of environmental sociology is the concept of carrying capacity, which describes the maximum amount of life that can be sustained within a given area. While this concept can refer to grazing lands or to rivers, we can also apply it to the earth as a whole.
Population, Urbanization, and the Environment
This week, in Lesson 11, we will examine a variety of issues within demography, population, the environment and collective behavior. Demographic measurements such as fertility and mortality rates will be studied as they pertain to demographic theories. Current population trends and patterns will be reviewed as we discover the social experiences of internally displaced people, asylum-seekers, and refugees. The process of urbanization will be studied as we learn about the function of suburbs, exurbs, and concentric zones. Challenges presented by pollution, garbage, e-waste, and toxic hazards will be considered along with the impact of climate change and environmental racism on specific demographic populations.
Malthusian theory
Thomas Malthus (1766-1834) was an English clergyman who made dire predictions about earth's ability to sustain its growing population. According to Malthusian theory, three factors would control human population that exceeded the earth's carrying capacity, or how many people can live in a given area considering the amount of available resources. Malthus identified these factors as war, famine, and disease (Malthus, 1798). He termed them "positive checks" because they increase mortality rates, thus keeping the population in check. They are countered by "preventive checks," which also control the population but by reducing fertility rates; preventive checks include birth control and celibacy. Thinking practically, Malthus saw that people could produce only so much food in a given year, yet the population was increasing at an exponential rate. Eventually, he thought people would run out of food and begin to starve. They would go to war over increasingly scarce resources and reduce the population to a manageable level, and then the cycle would begin anew. Of course, this has not exactly happened. The human population has continued to grow long past Malthus's predictions. So what happened? Why didn't we die off? There are three reasons sociologists believe we are continuing to expand the population of our planet. First, technological increases in food production have increased both the amount and quality of calories we can produce per person. Second, human ingenuity has developed new medicine to curtail death from disease. Finally, the development and widespread use of contraception and other forms of family planning have decreased the speed at which our population increases. But what about the future? Some still believe Malthus was correct and that ample resources to support the earth's population will soon run out.
Asylum-Seekers
Those whose claim to refugee status have not been validated.
metropolis
Together, the suburbs, exurbs, and metropolitan areas all combine to form a metropolis
Urbanization in the United States
Urbanization in the United States proceeded rapidly during the Industrial Era. As more and more opportunities for work appeared in factories, workers left farms (and the rural communities that housed them) to move to the cities. From mill towns in Massachusetts to tenements in New York, the industrial era saw an influx of poor workers into U.S. cities. At various times throughout the country's history, certain demographic groups, from post-Civil War southern Blacks to more recent immigrants, have made their way to urban centers to seek a better life in the city.
Urbanization
Urbanization is the study of the social, political, and economic relationships in cities, and someone specializing in urban sociology studies those relationships. In some ways, cities can be microcosms of universal human behavior, while in others they provide a unique environment that yields its own brand of human behavior. There is no strict dividing line between rural and urban; rather, there is a continuum where one bleeds into the other. However, once a geographically concentrated population has reached approximately 100,000 people, it typically behaves like a city regardless of what its designation might be.
Garbage
Where is your last cell phone? What about the one before that? Or the huge old television set your family had before flat screens became popular? For most of us, the answer is a sheepish shrug. We don't pay attention to the demise of old items, and since electronics drop in price and increase in innovation at an incredible clip, we have been trained by their manufacturers to upgrade frequently. Garbage creation and control are major issues for most core and industrializing nations, and it is quickly becoming one of the most critical environmental issues faced in the United States. People in the United States buy products, use them, and then throw them away. Did you dispose of your old electronics according to government safety guidelines? Chances are good you didn't even know there are guidelines. Multiply your electronics times a few million, take into account the numerous toxic chemicals they contain, and then imagine either burying those chemicals in the ground or lighting them on fire. Those are the two primary means of waste disposal in the United States: landfill and incineration. When it comes to getting rid of dangerous toxins, neither is a good choice. Styrofoam and plastics that many of us use every day do not dissolve in a natural way. Burn them, and they release carcinogens into the air. Their improper incineration (intentional or not) adds to air pollution and increases smog. Dump them in landfills, and they do not decompose. As landfill sites fill up, we risk an increase in groundwater contamination.
Demographic Transition Theory!
Whether you believe that we are headed for environmental disaster and the end of human existence as we know it, or you think people will always adapt to changing circumstances, we can see clear patterns in population growth. Societies develop along a predictable continuum as they evolve from unindustrialized to postindustrial. Demographic transition theory (Caldwell and Caldwell, 2006) suggests that future population growth will develop along a predictable four-stage model. In Stage 1, birth, death, and infant mortality rates are all high, while life expectancy is short. An example of this stage is the 1800s in the United States. As countries begin to industrialize, they enter Stage 2, where birthrates are higher while infant mortality and the death rates drop. Life expectancy also increases. Afghanistan is currently in this stage. Stage 3 occurs once a society is thoroughly industrialized; birthrates decline, while life expectancy continues to increase. Death rates continue to decrease. Mexico's population is at this stage. In the final phase, Stage 4, we see the postindustrial era of a society. Birth and death rates are low, people are healthier and live longer, and society enters a phase of population stability. Overall population may even decline. For example, Sweden is considered to be in Stage 4. The United Nations Population Fund (2008) categorizes nations as high fertility, intermediate fertility, or low fertility. The United Nations (UN) anticipates the population growth will triple between 2011 and 2100 in high-fertility countries, which are currently concentrated in sub-Saharan Africa. For countries with intermediate fertility rates (the United States, India, and Mexico all fall into this category), growth is expected to be about 26 percent. And low-fertility countries like China, Australia, and most of Europe will actually see population declines of approximately 20 percent. The graphs below illustrate this trend.
Climate Change
While you might be more familiar with the phrase "global warming," climate change is the term now used to refer to long-term shifts in temperatures due to human activity and, in particular, the release of greenhouse gases into the environment. The planet as a whole is warming, but the term climate change acknowledges that the short-term variations in this process can include both higher and lower temperatures, despite the overarching trend toward warmth. Climate change is a deeply controversial subject, despite decades of scientific research and a high degree of scientific consensus that supports its existence. For example, according to NASA scientists, 2013 tied with 2009 and 2006 as the seventh-warmest year since 1880, continuing the overall trend of increasing worldwide temperatures (NASA, 2014). One effect of climate change is more extreme weather. There are increasingly more record-breaking weather phenomena, from the number of Category 4 hurricanes to the amount of snowfall in a given winter. These extremes, while they make for dramatic television coverage, can cause immeasurable damage to crops, property, and even lives.
Inequitable Parts
Why does environmental racism exist? The reason is simple. Those with resources can raise awareness, money, and public attention to ensure that their communities are unsullied. This has led to an inequitable distribution of environmental burdens. Another method of keeping this inequity alive is NIMBY protests. Chemical plants, airports, landfills, and other municipal or corporate projects are often the subject of NIMBY demonstrations. And equally often, the NIMBYists win, and the objectionable project is moved closer to those who have fewer resources to fight it.
Green Policies
World systems analysis suggests that while, historically, core nations (like the United States and Western Europe) were the greatest source of greenhouse gases, they have now evolved into postindustrial societies. Industrialized semi-peripheral and peripheral nations are releasing increasing quantities of carbon emissions. The core nations, now post-industrial and less dependent on greenhouse-gas-causing industries, wish to enact strict protocols regarding the causes of global warming, but the semi-peripheral and peripheral nations rightly point out that they only want the same economic chance to evolve their economies. Since they were unduly affected by the progress of core nations, if the core nations now insist on "green" policies, they should pay offsets or subsidies of some kind. There are no easy answers to this conflict. It may well not be "fair" that the core nations benefited from ignorance during their industrial boom.
Projected Population in the United States
Worldwide patterns of migration have changed, though the United States remains the most popular destination. From 1990 to 2013, the number of migrants living in the United States increased from one in six to one in five (The Pew Research Center 2013). Overall, in 2013 the United States was home to about 46 million foreign-born people, while only about 3 million U.S. citizens lived abroad. Of foreign-born citizens emigrating to the United States, 55 percent originated in Latin America and the Caribbean (Connor, Cohn, and Gonzalez-Barrera, 2013).
Soil
You might have read The Grapes of Wrath in English class at some point in time. Steinbeck's tale of the Joads, driven out of their home by the Dust Bowl, is still playing out today. In China, as in Depression-era Oklahoma, over-tilling soil in an attempt to expand agriculture has resulted in the disappearance of large patches of topsoil. Soil erosion and desertification are just two of the many forms of soil pollution. In addition, all the chemicals and pollutants that harm our water supplies can also leach into soil with similar effects. Brown zones where nothing can grow are common results of soil pollution. One demand the population boom makes on the planet is a requirement for more food to be produced. The so-called "Green Revolution" in the 1960s saw chemists and world aid organizations working together to bring modern farming methods, complete with pesticides, to developing countries. The immediate result was positive: food yields went up and burgeoning populations were fed. But as time has gone on, these areas have fallen into even more difficult straits as the damage done by modern methods leave traditional farmers with less than they had to start. Dredging certain beaches in an attempt to save valuable beachfront property from coastal erosion has resulted in greater storm impact on shorelines, and damage to beach ecosystems (Turneffe Atoll Trust, 2008). These dredging projects have damaged reefs, sea grass beds, and shorelines and can kill off large swaths of marine life. Ultimately, this damage threatens local fisheries, tourism, and other parts of the local economy.
