Recommended: Negative effect of overpopulation
Earth’s population is increasing, and areas which are already home to millions are continuing to expand. As these cities continue to grow, when the population reaches a certain point it is referred to as a megacity, a megacity is a metropolitan area with a total population of 10 million plus. These megacities are so large that they are becoming out of control settlements, cities like Los Angeles and Tokyo are being forced to expand upwards due to having to accommodate for the thriving population. These cities are also faced with the issue of not having enough resources such as food and water to support the demand required. With megacities rampant growth with it bring a decline in the quality of life, to prevent this from getting worse laws are needed to be placed which is able to limit the population and physical boundaries.
It is evident through statics and data that megacities populations are increasing at a rapid rate and is getting to the stage where they are becoming out of control settlements. As cities begin to expand additional megacities are being produced or are continuing to grow meaning that the cities in which people are living in are evolving geographically outwards, upwards and in density. Megacities are agglomerations which are home more than ten million people with a range of density housing, sprawling estates and slums (Air Pollution, N/A). In order to maintain these dense areas, huge resources and work are required to ensure that services are being delivered. By living in a megacity it is obvious due to the large population in one area that there are huge demands on natural resources like water and food produce. The areas in which megacities are expanding are not big enough to provide sufficient resources to ...

...er cities and areas to live in. Governments may have to take into consideration, of possibly decentralizing public services to other regions or encouraging private business to relocate to other regions. This will allow mega cities to limit their population size and grow and expand to other more unpopulated areas.
Megacities are becoming an issue right across the world, some settlements like toyko are home to more that 37million people. With such a high population living in such a dense area with it brings a decline in the quality of life. There is the problem of the high amount of personal transport being used which is pollution the earth’s atmosphere as the issue of not having enough resources like food and water to support the demand required. By having national laws put in place, governments and councils are able to limit the population and physical boundaries.
However, there is usually not enough land or housing for the city's growing population. There is also not enough jobs in the city to keep everyone employed. Poverty increases and jobs give lower and lower pay. The poor live in slums
This view of the city reinforces Thomas Malthus’ principle of population because the earth had been so overpopulated that it could no longer support natural resources due to the lack of uncontrolled population. Due to the lack of population control, the Earth had become uninhabitable as it can be assum...
A metropolitan area and a megaregion both arch over many people and communities, but they are two very different entities. A Metropolitan area as defined by the federal government is an area that reaches across urban communities and a city, which also has 50,000 people or more living there. A Megaregion in contrast is an area that arches over multiple cities, urban communities, counties, and sometimes even states. A megaregion is essentially multiple metropolitan areas all bunched together. The difference between these two types of areas can be seen when examine the governments in each. In a Metropolitan areas coordinating policies ion things like transportation can be difficult because of the many layers of government in the region. A Megaregion experiences those same issues on an exponentially larger scale. Sometimes hundreds or thousands of jurisdictions overlap creating conflict and little to no organization and coordination. The mere difference in overlaps of governments makes a significant difference between a metropolitan area and a
Urban Consolidation Factors and Fallacies in Urban Consolidation: Introduction As proponents of urban consolidation and consolidated living continue to manifest in our society, we must ensure that our acknowledgment of its benefits, and the problems of its agitator (sprawl), do not hinder our caution over its continually changing objectives. Definition Like much urban policy, the potential benefits that urban consolidation and the urban village concept seek to offer are substantially undermined by ambiguous definition. This ambiguity, as expressed through a general lack of inter-governmental and inter-professional cohesion on this policy, can best be understood in terms of individual motives (AIUSH,1991). * State Government^s participatory role in the reduction of infrastructure spending.
Over the years, many cities, particularly large cities, around the world have had tremendous problems and had suffered massively from the huge number of population in that city. One of those massive cities is Mexico City. Mexico City, being very popular in Mexico, is unbelievably overpopulated. Several factors caused this overpopulation. This over population affects the people in many various ways negatively. It affects the geography and climate of the city, causes pollution, and a housing crisis.

Big cities have many advantages over small towns. Goods and services are more readily available. Greater selection means more competition which often results in lower prices for those goods and servic...
Indeed, many global cities face compelling urban planning issues like urban sprawl, population, low density development, overuse of non-renewable natural recourses, social inequities and environmental degradation. These issues affect the cities themselves, the adjacent regions and often even globally. The resulting ecological footprint upsets the balance in adjacent rural and natural areas. Unplanned or organic development leads to urban sprawl, traffic problems, pollution and slums (as evident in the case of Mumbai city). Such unplanned development causes solid waste management and water supply to fall inadequate. Urban sprawl gives rise to low density development and car dependent communities, consequently leading to increased urban flooding, low energy efficiency, longer travel time and destruction of croplands, forests and open spaces for development.
Nowadays, more than half of the world population lives in cities. Urban populations consume 75% of the world 's natural resources and generate 75% of waste. Cities have become consumers of enormous amounts of natural resources and generating massive environmental
First of all, overpopulation drastically affects the land. Possibly the most prominent example of the depreciating health and amount of land is the need for developments. Due to the exploding population in the United States, about 1.2 million acres of land every year is being converted to subdivisions, malls, workplaces, roads, parking lots, resorts, and many other developments (“Overpopulation,” Internet). That is a substantial amount of land being overturned to satisfy human desires. To put it in better perspective, between 1982 and 1997, the land mass lost to development is equal to the size of Maine and New Hampshire combined, which is approximately 25 million acres (“Overpopulation,” Internet). While soil is being ruptured for human preference, the number of cities has remarkably modified. In 1975, Mexico City, Tokyo, and New York City were the only cities considered as megacities (“Special,” Internet). In today’s world, that number is considerably small. Now, there are 21 megacities in the world. A megacity is when the population of that city becomes greater than 10 million people (“Special,” Internet). Therefore, the 21 megacities that are currently in the world holds more than 21...
The Negative Effects of Urbanization on People and their Environment As our world becomes increasingly globalized, numerous people travel to urban areas in search of economic prosperity. As a consequence of this, cities in periphery countries expand at rates of 4 to 7 percent annually. Many cities offer entrepreneurs the potential for resources, labor, and resources. With prosperity, cities also allow the freedom of a diversity of ways of life and manners (Knox & Marston, 2012). However, in the quest to be prosperous, increasing burdens are placed on our health and the condition of our environment.
...population distribution designed to reduce the rate of rural-urban migration appears to have had limited success in many developing countries. Policies must be directed at altering the rural economy in order to slow the rate of urban sprawl. Broad land use planning and changing of planning standards and governmental procedures would go a long way to reduce many of the problems that face urban populations in the developing areas, especially Africa. Urbanization can cause a lot of problems for a city or even a country. It can cause cities to become overpopulated which are known as mega-cites, and cause problems with living arrangements and finding a job. Urbanization can also cause health problems. Urbanization is supposed to be good for developing countries on the rise but with this rapid growth in Africa, these problems can become a major concern in the future.
With the development of urbanization, an increasing number of social problems have emerged. These problems will decelerate the urban development, however, there are many ways in which sustainable development can reduce the impact of these urbanization problems. “Sustainable development seeks to improve the quality of human life without undermining the quality of our natural environment” (Adams, W.M. 1999). Actually, sustainable development can partly solve the urbanization problems, for it can reduce the impact of the problems such as traffic jam, housing shortage and severe pollution, but it is difficult to completely solve these problems in a short time.
Cities all over the world are developing. As war ended in 1942, a significant number of people move to the city because they want to improve life. This urbanization process is causing a number of problems and should be met by sustainable development policies. In the beginning, it is important to know the definition of sustainable development. There are some definitions for sustainable development, but simply they say that sustainable development is a development which using resources now and preserving them for future generations (Adams, 1999, p.137). This concept has been agreed internationally at a Rio Conference in 1992 to be implemented by all government policies which mostly known as “Agenda 21” principles (Adams, 1999, p.141). This paper will show that traffic jams and housing problems caused by urbanization can be met by sustainable development policies. The structure of this paper will first explain the situation that leads to traffic jams and housing problems. Next, it will elaborate the sustainable development solutions, implications for the solutions, and evaluations how effective the sustainable development solutions solved the problems.
There are three kinds of development in megacities we would like to explore in this paper, they are sustainable development, economic development and human development. Those kinds of development face many problems in megacities. In 1950 there were only New York and Tokyo as megacities and now in this 21 century the number of megacities are increasing.In 2013 noted there are 28 megacities (New Geography, 2013). Industrialization in developing countries is the main reason why the poor peasant in rural area moved to the cities in the name of better job and higher wages. This urbanization will change the population proportion which is decreasing the rural population and on the other side, increasing the population of urban areas. This continuing movement will inevitably create big and even bigger community in the city and in the end a megacity will be formed. This big number of population influences development of megacities.
