Aviation and the Global Atmosphrer Report Essay

Aviation and the Global Atmosphrer Report - Essay Example In 2004 the UK ranked number six in the world league of tourism earnings, and tourism is a major component of the UK economy, accounting for 3.5% of UK GDP. The tourism industry directly supports 1.4 million jobs, or some 5% of total UK employment and one fifth of all international air passengers in the world are on flights to or from a UK airport. Airports are critical for the development of local and regional economies. They generate employment, open up wider markets and attract businesses to an area. They are also increasingly important transport hubs, particularly for the logistics industry. But Air travel is the world's fastest growing source of greenhouse gases like carbon dioxide, which cause climate change. The huge increase in aircraft pollution is largely due to the rapid growth in air traffic. This means increasing airport capacity, more flights, more pollution and increasingly crowded airspace. People living near airports have long suffered from aircraft noise, traffic co ngestion and air pollution. Indeed communities around airports have been concerned about these issues for years. Aircraft emissions can also have a significant effect at ground level. Air and ground traffic at major airports can lead to pollution levels as high as city centers. Several steps have been taken by the various governments and airports to mitigate these impacts of air traffic. New airports policy specifically addresses how harmful greenhouse gases from aircraft will be reduced and that adequate resources are put into encouraging alternatives to flying. But people around airports are more concerned about environmental impacts and protesting even expansion of airports. Manchester airport in UK experienced the same kind of protest. But when we analyzed the cost-benefits of developments especially social and environmental costs and loss of economic activities, it clearly shows that though aviation may cause greenhouse gases emission but have not established yet the quantity o f adverse impacts whereas economic losses could be quantified. So the more sustainable developments are recommended and pursued by the airports and the governments equally. Introduction: The aviation industry is defined as those activities that are directly dependent on transporting people and goods by air to from and within. This covers airline and airport operations and includes scheduled and chartered flights for passengers and freight, general aviation, aircraft maintenance, air traffic control, and activities directly serving air-passengers, such as check in baggage handling and on-site retail and catering facilities. In an increasingly globalize economy the aviation industry is a vital element of the UK's transport infrastructure. Benefits of aviation industry growth: The aviation industry directly contributed 11.04 billion pound to UK GDP in 2004 and employed 186,000 people. Over 520,000 jobs in UK in total depend on the aviation industry. Visitors arriving by air contribute over 12 billion pound a year to

MIH548 - Theory Based Research - Mod 1 SLP Essay

MIH548 - Theory Based Research - Mod 1 SLP - Essay Example Since these are chromic acquired diseases, these are preventable. Again current research has indicated that physical activity should be promoted as a public health measure in order to prevent these conditions, and absence of many of these conditions in itself is physical wellbeing. However, public health policies have failed to promote physical activities in a large scale across communities, and thus there must be a gap in understanding these barriers in implementation. This calls for a theoretical research in order to update the current knowledge and to identify any gap in the knowledge, so a practical guideline for the physical activity promotion may be created. In order to do that three studies on the topic of association between physical activity and wellbeing will be chosen for critical review, so a summary of theory of this association can be made based on these studies. Thus based on key words â€Å"physical activity† and â€Å"wellbeing† a literature search was conducted in the ProQuest database, and three very recent articles were identified to critically review them in order to establish the association. Since â€Å"wellbeing† is a term that is age nonspecific, the selection criteria would include research done on any age group. Some mental health studies were located which correlated between physical activity and mental health, and it was decided that at least one study will be included in the review which examines public health implications of physical activity from the mental wellbeing point of view. The objective of this study was to examine the effects of 17 weeks of micronutrient supplement as opposed to physical exercise on the psychological wellbeing in the elderly population. The sample chosen was a group of 139 frail elderly subjects who were living in independent living facilities. All the participants at baseline were physical inactive due to frailty with either weight loss or body mass index of less
