Many people see health in different ways, this essay will look at two concepts of health, the biomedical and the social medical, and evaluate them. This will try to give a more rounded look at the approaches, the problems they can show and the things that are not taken into consideration. To be able to do this we first need to be able to define what ‘health’ is. This term can be described in many ways; the English dictionary defines health as “the general condition of the body or mind with…

On the 3rd November 2016 the Hazelwood Power Station, which produced brown coal in the Latrobe Valley, announced the entire plant would close at the end of March 2017. After supplying electricity to Victoria for over 50 years, the plant’s owners Engie argued that it was no longer economically viable to continue to run one of Australia’s most ‘dirty’ power plants, thus laying off almost 1,000 jobs. Engie states that the growing pressure for renewable energy was the main factor for the closure of…

Definition of ecological problems in today’s context is taken as environmental problems and the most important ecological problem is the air pollution. This issue has a long history and is impacting on the health of the individuals since 500 BC. Various human activities of that time have emerged and evolved with the passage of time and thus extended environmental issues. Air pollution is one of the major ecological problems. Environmental problems were first discovered at the time of ancient…

Chemical Warfare: An “Unconvential” threat Throughout the history of war, techniques and use of weapons in warfare have been improved over the years. Although some weapons and certain techniques are entirely new, the use of certain weapons such as Chemical Warfare have been around since WW1. Many have thought of Chemical Weapons as being too dangerous while others think it is necessary and essential to modern warfare. What threats does Chemical warfare pose to soldiers and civilians around the…

Carbon tax has been imposed in many jurisdictions around world. It is one of the initiatives to stop the menace of global warming. This global warming, which has slowly raised the earth 's temperature somewhere between one and two degrees over the past one hundred years, may have dire effects. As a result of higher temperatures, the ocean levels will rise, global weather patterns will be permanently altered, and ecosystems around the world will be greatly affected. Sweden 's Carbon Tax is one…

which produces a powdered form of carbon with a very high surface to mass ratio. This is usually highly agglomerated but has a primary particle size which can be of the order of 100 nm. Worldwide production of carbon black was approximately 6 million tonnes in 1993 (IARC,1996). Other common materials produced by flame pyrolysis or similar thermal processes include fumed silica (silicon dioxide), ultrafine titanium dioxide (TiO2) and ultrafine metalssuch as…

P2 Describe how over extracting raw materials causes global pollution Pollution is when pollutants (usually green house gases) are released into our atmosphere and contaminate it. Green house gases are the pollutants that are commonly known for contributing to global warming. When extracting raw materials from our earth we do more damage than we think, in order to build our desired project we must take our materials from the earth. This process is known as the extraction of raw materials In…

GEOS2121 Essay – Question 2 Identify a pertinent environmental concern (eg. climate change, fisheries depletion, deforestation, soil degradation, river health, etc) and discuss how population changes at the global and local levels may impact on the issue. Explain why various change(s) in demographics may or may not result in improvement to the environmental management of this issue. Humanity and our environment are a complex relationship that exists in a delicate balance, yet a growing…

“We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity” (Edward Owen Wilson, 2006). The Great Barrier Reef (GBR) was inscribed on the World Heritage List in 1981 and stretches for more than 2300 kilometres along the northeast coast of Australia, including an area of about 347 800 square kilometres of seabed. It is the largest coral reef ecosystem in the world with 2500 coral reefs and is home to more than 1500…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…
