Such an increase in demand is leading to other areas having decreased amount of resources. Also, having megacities with such high demands of the environment is leading to increased pollution in cities. The pollution from cars, airplanes, and industrialization is harming over the 10 million people in each megacity. The long-term effects of having megacities are unknown, but already proving how they can be hazardous to the people living there and those around
Primarily, air pollution, overconsumption, and imbalance are fruits of urban sprawl. Three chief disadvantages of urban sprawl are increased types of pollution, consuming green lands, and imbalance of lifestyle system. One significant disadvantage of urban sprawl is the increased pollution caused by many factors. The increase of people and cars, and the expansion of people affects the environment. Different means of transportation, such as cars, buses, and trains cause both noise
When the city development, urban heat island, effect becomes more and more severe. Urban Heart Island means that refers to the city due to a large number of artificial fever, buildings and roads and other high-heat storage and green space reduction and other factors, resulting in the city "high temperature". Cities are the most obvious places where the global environmental change and health problems cross each other. The available evidence confirms that global climate change is leading to more and more intense extreme heat / cold events. Interactions between extreme hot / cold events and pollution lead to increased morbidity and mortality in urban-susceptible populations.
When ecosystem services are altered, their capacity to satisfy even basic human needs starts to be compromised (Vitousek, et al, 1997) The FIG commission, 2010, posits that urbanization comes with negative and positive impacts depending on how it is managed or planned for. Urbanization brings along development which in turn gives rise to higher living standards, which will also give rise to further urbanization. Poorly planned rapid urbanization carries with it grave consequences in the form of urban environmental hazards which include flash floods, mudslides and the like. These hazards increase as urbanization increases. Thus there is need to plan and properly manage the process rapid urbanization (Nyambod, 2010).
1. Introduction 1.1. Definition of a Slum and Slum Tourism According to the United Nations, a slum is a run-down settlement located in the urban area of a city where communities do not have access to clean water, sanitation and tenure security (Slums: Some Definitions, 2007). Slum tourism is visiting these impoverished areas. It is becoming one of the fastest-growing special interest tourism segments, but it is also one of the most controversial out of the different special interest tourism (Ma, 2010).
This, Simon notes, is not the result of a political decision but a powerful combination of socio-economic segregation and ethnic-racial discrimination. Cities struggle between trends of cultural homogenisation and heterogenization. The homogenisation process imposes certain fixed identity on the right to city.Many cities in the world are socially, economically and ethnically fragmented. Some of them are even becoming socially, ethnically and racially ghettoised. In one hand, Intergroup encounters happens in increased number in a city, and they develop can develop and cultural production take place.
With over seven billion people in the world, the Earth is suffering from the destruction humans have caused. Overpopulation is caused by exceeding the carrying capacity and has affected many different countries. By damaging and upsetting the stability of the world, the environment is affected in many different ways. Also, it becomes challenging for undeveloped nations to find alternative methods of production, due to the inadequate amount of resources available. Altogether, overcrowding negatively affects the environment.
There is a reason why popular novelist Dan Brown – author of ‘The Da Vinci Code’ and ‘Angels and Demons’ – mentioned Metro Manila’s monumental traffic jams in his book ‘Inferno’ (Flat Planet, 2014). Traffic congestion is prevalent primarily in the cities. The main avenues of cities and even the secondary roads are often congested, and the problems of traffic congestion have become so stern that the economy is pretentious. While total reduction of congestion is next to impossible in the Philippines, unswerving and staid efforts to improve transportation infrastructure for Metro Manila including much delayed mass transport systems can translate to indisputable benefits. Many studies have been indited on the economic costs of congested traffic, and they customarily consider such factors such as cost of traffic value of time lost due to delay, fuel prices, conveyance operating costs, effects on health, and greenhouse gas emissions (Traffic Problems in the Philippines and Proposed Solutions, 2014).
3. Pollution Prone to increased air pollution due to the concentration of infrastructure in the area which have serious repercussions on the environment. Section 2 (25%) Pick: ONE CONTINENT FROM THE GLOBAL NORTH (Choose Europe OR Northern America OR Oceania) and ONE CONTINENT FROM THE GLOBAL SOUTH (Choose Asia OR Africa OR Latin America and the Caribbean) For the Global North continent: What is the trend with regards to urban population and city
Increasing population, booming economies, rapid urbanization and the rise in the community living standards have all greatly accelerated solid waste generation rate in developing countries at the municipal level (Minghua et al, 2009). According to ISWA and UNEP, (2002) “with … limited resources, only basic technologies for treatment and disposal, and deficient enforcement of relevant regulations, serious problems remain for municipal solid waste management of developing countries” (cited in Chen at el, 2010:716). To the United Nations (UN), rapid urban growth throughout the developing world has seriously outstripped the capacity of most cities to provide adequate services to their citizens. The institutional capacity of developing countries at the municipal level is lagging in relation to waste generation trends. As a result, cities of developing countries are environmentally polluted and public health is under threat from widespread waste
