Feasibility of Different Techniques for Providing Fresh Water - 1.0 INTRODUCTION There has been a significant water crisis in various regions of the world over the last few years. Only about 3% of the water in the world is fresh; therefore there is relatively little fresh water available in some regions of the world, these regions are called arid and semi arid regions. The FAO (1987, cited in IFAD,n.d) defines arid and semi arid regions as “areas falling within the rainfall zones of 0-300 mm and 300-600 mm, respectively”. In other words, arid and semi arid regions are regions in which there is insufficient rainfall and rainfall patterns are liable to significant fluctuations....   [tags: management, crisis, technology]

Does Religion belong in Public Schools? - When looking at the history of America, it is fascinating to see how the public schooling system even got started. The first schools in America were not public schools, as many would presume. Instead, “the first schools in the United States were religious and not secular” (Elifson 1). Nearly all public schools, up to the 1960’s incorporated religion and prayer in their classrooms; however, in the last 50 years, prayer and religion in public schools has been debated over countless times. Even in Hudsonville, Michigan, which holds the record in the Guinness Book of World Records for having the most churches on a single street, there is much debate over prayer and the teaching of Christianity,...   [tags: Religion]

Breeding Habits of Water Birds - Chapter 1. INTRODUCTION Many species aggregate for feeding, roosting and nesting activities, which are prevalent among water birds (Weins, 1992). Why animals form breeding colonies is a major unresolved question in evolutionary biology. The topic continues to stir lively debate (Danchin & Wagner 1997, Tella et al., 1998) and has been the focus of long term studies (Hoogland 1995; Brown & Brown 1996; Danchin et al. 1998). One of the principal issues has been whether colonies form due to limited breeding habitat; with animals forced into nesting aggregations at a nest cost, or result from social benefits of clustering (Food finding, reduced predation; Lack 1968; Alexander 1974; Hoogland & Sh...   [tags: Biology ] 976 words

Climate Change and Agricultural Resources - Water. Water is the basis for life on earth. It hydrates our agricultural resources, powers our hydroelectric power stations and is essential for human hydration, sanitation, and all around survival. So it’s lucky that on earth, 70.8% of the surface is covered with water, however 97% of that water is high salinity seawater. The remainder is fresh water, but in that sliver of fresh water, only 25% is fluid water with 75% locked in polar ice caps in the arctic and Antarctica. Even though we can’t reach them, we’re contributing to the greenhouse effect (which effectively melts the caps and raises the sea level)....   [tags: Water, Hydroelectric Power Stations]
