With urbanization comes expansion when this happens cities must make more roads, buildings, roads and homes to accommodate its population. When this happens there are large pieces of land that are destroyed reducing natural recourses and increasing greenhouse gases. This causes a massive amount of air pollution to one general area. Although carbon dioxide is a massive cause to air pollution outdoors there are still many indoor atmosphere pollutions that we breathe in every day. Cigarette smoke is one of the leading causes of indoor pollution in homes, the cigarette smoke a person breathes in does not only affect them personally but all the people around them as well.
Poor people are moving into slums because the city design has no space for them and this lack of space causes slums to become more and more dense. Santiago, Chile recognizes the influx of population to urban areas.
The Affects on Human’s and the Environment Katrina Doughty Everest University September 2011 Air pollution consists of gases and fine particles. Each type of air pollution has different effects upon the environment and human health. Air pollution affects are many, and they may be really harmful. Three factors determine the levels of air pollution are the amount of pollutants entering the air, the amount of space into which the pollutants are dispersed, and the mechanisms that remove pollutants from the air. Sulfur dioxide is a noticeable component in the atmosphere.
Issues are views or concerns that people may hold about a feature or event which may be beneficial or problematic. Examples of urban issues are crime, pollution and overpopulation. Overpopulation is an issue which is rapidly affecting cities across the globe, and can have a detrimental impact on urban areas. Hyper-urbanisation is a problem which can stem from this. This is caused when a city’s population increases at a faster rate than the growth of economic and industrial development, which results in a strain on resources.
Lots of people means over crowded places. Then, people produce garbage, and being a big population they will not recollect the contamination as fast as it is produced being an important pollution cause on the world. Besides waste, another way to see that population growth as a cause of pollution is that cities become being bigger and as big is the city, big is the pollution on it. Also, Transports are another source of pollution related with population growth. For example, a research found that USA 60% of the gas pollution is caused by auto vehicles.
A similar effect has happened in the city of Exeter. In Exeter, there has been suburbanisation, but with the majority of those moving being businesses, not people. Businesses have moved from the inner city to the suburbs and this has caused lots of problems. Mainly, it has effected in the increased outward expansion of urban areas, reducing the amount of green sites in the area. Parts of the Green Belt are also being invaded as a result of the expansion.
Lacia Vaughan 5 November 2012 ENGWR 102 The Effects of Urban and Rural Living What is the difference between Urban and Rural living? What are the pros and cons of living either of these different lives? Lets us see. Urban Sprawl is the uncontrolled spread of urban areas, usually taking place on the outskirts of cities, involving the mass construction of residential areas and commercial buildings. Two causes for this being the fact that land and housing costs are cheaper compared to cities, and higher property and business taxes have pushed businesses to the suburbs where taxes are typically low.
I will be covering the aspects, causes and effects of Global Warming. There are many definitions of Global Warming. One of these is that “ Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate.”(EPA) The temperature increase can lead to changes in the average rainfall results, the sea levels can rise, and it may have many impacts on wildlife, plants of humans. The Global Warming is mainly cause by humans. The Green House Effects is one of the main causes of this warming.
Environmentally sustainable pollution management To begin with pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to physical systems or living organisms. This occurs at very high levels in densely populated areas such as megacities. In large cities, the ministries of the environment usually handle important issues concerning the pollution levels in the cities. These can be managed using various strategies which lead to environmental sustainability such as reducing waste disposal by improving the recycling in a city, forcing stricter measures regarding the emissions of both private and public companies and by improving the public transport. Mexico City is one of the largest cities in the world with a population close to twenty million people.
Owing to the development of industry and the use of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere has produced and the average global temperature seems to have risen. What’s more, deforestation can affect climate changes. The growing of trees and plants can absorb carbon dioxide from the atmosphere because of photosynthesis, however, deforestation lead to carbon dioxide emissions. Both of these can lead to global warming of the atmosphere. The report (UNEPWMO, 2004, P10) also pointed out, the burning of fossil fuels and deforestation are altering the composition of the atmosphere and contributing to climate change.
