Biodiversity loss has a negative impact on our societies; it negatively affects or contributes to the health of individuals, the climate, natural resources, pollution, poverty and the extinction of species. In the past years, biodiversity has been increasing faster than at any other time in human history. Consequently, its metamorphosis is anticipated to continue at the same pace. Virtually, all of Earth's ecosystems have been severely transformed as a result of human actions and ecosystems...
Various physical, chemical and biological hazards that affect human health arise in the built environment, there is need for more awareness by both the designers and building occupants so that necessary preventive measures will be incorporated in the design of new build and proper remedies will be applied in the case of dealing with existing environments. Consequently, along with case studies of sick building syndrome and comparative evaluation of construction health and safety legislatives in...
Since more than 4 million years and insects found on the surface of the earth attack humans and damage it to occur to him directly and indirectly, and they began trying to get rid of these insects, consider how to exterminate them and get rid of the harm caused was trying to get rid of manual methods by combining, killing and The first use of pesticides is the use of chemical toxic compounds of arsenic, especially arsenate of lead and other heavy elements, and was the third arsenic oxide...
Owing to increasing public awareness of declining supplies of non-renewable and finite fossil energy resources and pronounced environmental impacts of fossil fuel use, the world is currently experiencing an energy crisis.1 The global energy crisis is an acute turning point in the supply of the world energy resources which makes dramatically rising in oil price. Not only transportations using petroleum fuels, such as gasoline and diesel, are affected by these increased petroleum prices, but...
The area within the site boundary is approximately 185.1ha of which approximately 8.05ha will be used for the proposed wind farm. Minimal habitat will be lost as a consequence of the construction of the wind farm. The site is located within the former Earlseat OCCS at which coal extraction ceased in 2009. The proposals have been developed to integrate with the Earlseat restoration plan for the site.Wind-farms might affect birds by increasing mortality rates through collisions, by disturbance...
Solar power is considered to be a clean energy source of the future having the most potential. There are various ways and systems for converting sunlight to electricity. These include flat-panel photovoltaic systems, thin-film solar systems and concentrator solar systems. Intensive research is currently taking place in order to make solar-energy generated electricity competitive with coal-generated electricity. The research is done in order to identify the ways of lowering the cost of...
The project that I have decided to undertake is to gain a better understanding of small scale wind power. The topic of wind power is one that I have previously studied and so however I have not as of yet studied 'small scale wind power' in any great depth. My aim of this project is to produce a comprehensive and in depth report into how small scale wind power can be used to harness electricity. At the end of this project I would like to understand how small wind turbines work mechanically, the...
There has been many rumours and speculation about the world. Some are taken seriously, and others not as much. The priority in which these perspectives are set by people will depend on a variety of external and internal factors. Will the world end in 2012? There has been historical and present evidence that has been presented by recognized people, but is it believable? If our planet Earth does not end in 2012, what will people think? What is believable is the looming danger of our planet...
Natural Disaster is the effect of natural hazards which includes flood, tornado, volcano eruption, earthquake or landslide that affects the environment, leads to financial, environmental and/or human losses. It is terrible event that is not caused by human activity and results in deaths, injuries or damage to property. The resulting loss depends on the capacity of the population to support or resist the disaster, and their resilience. This perceptive is concentrated in the formulation:...
We are living in the age of 21st century where scientific inventions have change the life style of a common man completely. We developed a lot of new technology without considering that these developments can harm us in many ways. Changing lifestyles, the increasing use of disposable materials and excessive packaging are all contributing to an increase in the amount of waste being created. Waste management is now a global concern. Inadequate collection and disposal of waste poses a serious...
