Climate change - Dissertation ExampleThere is some division in the literature about the percentage of emissions ca subroutined by each sector. Whitaker (2007, p.62), for example, produces a very conservative look for run fuels, of just 14% of total emissions. Nevertheless, even Whitakers figures progress clear that urban communities are producing unsustainable levels in other areas for example, power stations to supply their energy are held responsible for 21.3% of greenhouse splash output, 10.4% are caused by residential and commercial sectors, and a further 3.4% is caused by waste disposal and treatment. The proviso of the latter on a large-scale in hardly necessitated by the large-scale existence of urban settlement patterns. International flip-flop, travel and a growing dependence on motor vehicles has made transportation one of the major sources of greenhouse gases. The growing numbers of people living in urban communities make a major contribution to this. As well as travelling between cities and within cities, they do not, of course, produce their own food and drink. Therefore, all of the necessities of every day life, and much else besides, has to be imported to the urban environment, at great cost to gas emissions. As was pointed out by several sources, the Kyoto Protocol the bourn international agreement on reducing greenhouse gas emissions, did not apply to emissions from international trade and transport by air and sea. Furthermore, as urban settlements grow and sprawl into the previously rural hinterlands, the distances which subscribe to to be traversed within cities become greater, which leads to increased ownership of cars and motorbikes. In the United States, for example, 92% of households own at least one car, and transport is the second largest contributor to US gas emissions, and, perhaps more worrying, an dumbfounding 35% of the worlds total (Dow & Downing, 2007, p.46). The United Kingdom has seen similar patterns, with car j ourneys increasing by 9% between 1997 and 2004, and anticipate to grow by a further 26% between 2000 and 2010 (Department for Transport, 2005, p.10). any(prenominal) sources took a more literary approach to the problems of climate change and urban sustainability, much(prenominal) as the use of a quote from Ehrenburg, penned in 1929, presaging the destruction wrought by the motor vehicle the automobile poopt be blamed for anythingIt only fulfils its destiny it is destined to wipe out the world (1999, p.175). Compared to the alternatives, such as using bicycles, trains and buses, which are relatively energy-efficient, using personal motor cars, especially if they are carrying only one or two people at a time, is damaging. However, the most sustainable type of transport walking, has become less popular. In the past decade, as Monbiot points out, the number of walking pilgrimages in the UK has fallen 20% (2006, p.145). At the same time, air travel is becoming ever more affordable, with passenger miles only expected to increase in the course of the next few decades. Dow and Downing provide a useful corroborate of figures for transport emissions, and their global distribution, and estimate that from 3.9 billion journey by air in 2004, by 2020 in that respect were will some 7.4 billion (2007, p.46). Each of these journeys is responsible for huge amounts of carbon dioxide emissions, with a round trip between Europe and the US by two people producing the equivalent of at least 40 tonnes of carbon
