need to combine two key global aims in the development of human activities: to accelerate human development‚ particularly in the poorest countries‚ and to remove the gross inequities present in the world today; while at the same time avoiding the depletion of the resources and biological systems of the planet to such an extent that future generations will be impoverished. The idea of sustainable development was well summarised by the report of the World Commission on Environment and Development‚ ~

The Poetry of Bruce Dawe Weapons Training The poem "Weapons training" composed by Bruce Dawe‚ explores the realities of war. The poem is situated in the period of the Viet-Nam war to prepare recruits for war. Dawe‚ uses a wide variety of techniques to further convey the harsh realities of war. The poem is a forceful text that is design to shock the audience and to bring out an emotional response. Bruce Dawe‚ writes poems on his own experiences in his life‚ living during many periods of conflicts

in weather patterns. Weather patterns have been changing recently due to the global warming up the process and its major reason – the greenhouse effect. The greenhouse effect is created by carbon dioxide emissions‚ released from the burning of fossil fuels (coal‚ oil and gas) in rich countries and a constantly increasing number of cars. Humans generate about 24 billion tonnes of carbon dioxide each year. It doesn’t take long to realise that there is no realistic chance of solving the greenhouse problem

Climate change is a tangible problem and its existence can no longer be denied. It is one of the most important scientific‚ economic threats facing to the earth. There are many factors lead to climate change‚ such as greenhouse gases‚ carbon dioxide‚ fossil fuels. Although it would be self-deception to believe that humans had nothing to do with it‚ the fact is that human activities caused negative

Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many countries and is harmful to humans’ and animals’ health‚ the environment and also

The main cause of greenhouse gasses is the use of fossil fuels. Our usage of fossil fuel is shown from the table 10.1 by Wetherly and Otter (2nd edition) that is linked to the population growth of 3.6bn to 6.1bn from 1970 to 2000.

or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles and airplanes in early 20th century‚ fossil fuels have been the most prominent source of energy. Fossil fuels fulfill most of the energy requirement of the world because of which energy produced from other sources are regarded as alternative energy. Fossil fuels are found in a limited amount which puts it into a high risk of depletion. So

Environmental Remediation Another aspect of “Going Green” involves removing contaminates from the soil‚ air‚ and water. These processes range from chemical to biological. Industry is responsible for much of the contamination and the government has enforced strict regulation to swing it.

Fuels obtained from biomasses could become a valid alternative to the use of fossil fuels‚ also in the light of the more and more stringent environmental constraints. In the outline of alternative liquid fuels‚ oils obtained from the pyrolysis of wood‚ generated recycling wood industry scraps‚ appear to be very promising as concerns their use in power plants and diesel engines.
