Modernization Modernization refers to a model of a progressive transition from a “pre-modern” or “traditional” to a “modern” society. The theory looks at the internal factors of a country while assuming that, with assistance, “traditional” countries can be brought to development in the same manner more developed countries have. Modernization theory attempts to identify the social variables that contribute to social progress and development of societies, and seeks to explain the process of social evolution. Historians link modernization to the processes of urbanization & industrialization, as well as to the spread of education. In sociological critical theory, modernization is linked to an overarching process of rationalization. When modernization increases within a society, the individual becomes that much more important, eventually replacing the family or community as the fundamental unit of society.

Overpopulation Overpopulation occurs when a population of a species exceeds the carrying capacity of its ecological niche. Overpopulation is a function of the number of individuals compared to the relevant resources, such as the water and essential nutrients they need to survive. It can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources. Species are bound by the resources they can find in their environment, but this does not necessarily control overpopulation, at least in the short term. In fact, an abundant supply of resources can produce a population boom that ends up with more individuals than the environment can support. In this case, starvation, thirst and sometimes violent competition for scarce resources may effect a sharp reduction in population in a very short lapse (a population crash).

The human population has been growing continuously since the end of the Black Death, around the year 1400, although the most significant increase has been in the last 50 years, mainly due to medical advancements, increases in agricultural productivity and the historically-unique availability of abundant cheap energy. The rate of population growth has been declining since the 1980s. Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion. Depending on which estimate is used, human overpopulation may or may not have already occurred.

The InterAcademy Panel Statement on Population Growth, circa 1994, has stated that many environmental problems, such as rising levels of atmospheric carbon dioxide, global warming (climate change), and pollution, are aggravated by the population expansion. Other problems associated with overpopulation include the increased demand for resources such as fresh water and food, starvation and malnutrition, consumption of natural resources (such as fossil fuels) faster than the rate of regeneration, and a deterioration in living conditions. However, some believe that waste & over-consumption, especially by wealthy nations, is putting more strain on the environment than overpopulation. The conservation movement, also known as nature conservation, is a political, environmental and a social movement that seeks to protect natural resources including animal, fungus and plant species as well as their habitat for the future.

Conservation The conservation movement, also known as nature conservation, is a political, environmental and a social movement that seeks to protect natural resources including animal, fungus and plant species as well as their habitat for the future. The early conservation movement included fisheries and wildlife management, water, soil conservation and sustainable forestry. The contemporary conservation movement has broadened from the early movement’s emphasis on use of sustainable yield of natural resources and preservation of wilderness areas to include preservation of biodiversity. Some say the conservation movement is part of the broader and more far-reaching environmental movement, while others argue that they differ both in ideology and practice. Chiefly in the United States, conservation is seen as differing from environmentalism in that it aims to preserve natural resources expressly for their continued sustainable use by humans. In other parts of the world conservation is used more broadly to include the setting aside of natural areas and the active protection of wildlife for their inherent value, as much as for any value they may have for humans.

Urbanization refers to the increasing number of people that live in urban areas. It predominantly results in the physical growth of urban areas, be it horizontal or vertical. The United Nations projected that half of the world’s population would live in urban areas at the end of 2008. By 2050 it is predicted that 64.1% and 85.9% of the developing and developed world respectively will be urbanized. Urbanization is closely linked to modernization, industrialization, and the sociological process of rationalization. Urbanization can describe a specific condition at a set time, i.e., the proportion of total population or area in cities or towns, or the term can describe the increase of this proportion over time. So the term urbanization can represent the level of urban development relative to overall population, or it can represent the rate at which the urban proportion is increasing.

Urbanization is not merely a modern phenomenon, but a rapid and historic transformation of human social roots on a global scale, whereby predominantly rural culture is being rapidly replaced by predominantly urban culture. The last major change in settlement patterns was the accumulation of hunter-gatherers into villages many thousand years ago. Village culture is characterized by common bloodlines, intimate relationships, and communal behavior whereas urban culture is characterized by distant bloodlines, unfamiliar relations, and competitive behavior. This unprecedented movement of people is forecast to continue and intensify in the next few decades, mushrooming cities to sizes incomprehensible only a century ago.

Eric Hobsbawm’sbook The Age of Revolution: 1789–1848 (published 1962 and 2005) chapter 11, stated “Urban development in our period [1789–1848] was a gigantic process of class segregation, which pushed the new laboring poor into great morasses of misery outside the centers of government and business and the newly specialized residential areas of the bourgeoisie. The almost universal European division into a ‘good’ west end and a ‘poor’ east end of large cities developed in this period.” This is likely due the prevailing south-west wind which carries coal smoke and other airborne pollutants downwind, making the western edges of towns preferable to the eastern ones. Similar problems now affect the developing world, rising inequality resulting from rapid urbanization trends.

The drive for rapid urban growth is often accompanied by the growth of slums. In many cases, the rural-urban low skilled or unskilled migrant workers, attracted by economic opportunities in urban areas, cannot find a job and afford housing in cities and have to dwell in slums. While cities certainly have a larger variety of markets and goods than rural areas, infrastructure congestion, monopolization, high overhead costs, and inconvenience of cross town trips team up to make marketplace competition as often as not worse in cities than in rural areas.

The phenomenon of “urban heat islands” has become a growing concern. Incidence of this phenomenon as well as concern about it has increased over the years. An urban heat island is formed when industrial and urban areas are developed resulting in greater production and retention of heat. A large proportion of solar energy that affects rural areas is consumed evaporating water from vegetation and soil. In cities, where there is less vegetation and exposed soil, the majority of the sun’s energy is absorbed by urban structures and asphalt. Hence, during warm daylight hours, less evaporative cooling in cities results in higher surface temperatures than in rural areas. Vehicles and factories release additional city heat, as do industrial and domestic heating and cooling units. As a result, cities are often 2 to 10 °F warmer than surrounding landscapes. Impacts also include reducing soil moisture and a reduction in re-uptake of carbon dioxide emissions. The phenomenon of “urban heat islands” has become a growing concern.

A July 2013 report issued by the United Nations Department of Economic and Social Affairs warns that with the additional 2.4 billion people by 2050, the amount of food produced will have to increase by 70 percent straining food resources, especially in countries already facing food insecurity due to changing environmental conditions. The mix of changing environmental conditions and the growing number of people living in urban regions, according to UN experts, will strain basic sanitation systems, health care, and potentially cause a humanitarian and environmental nightmare.
