Solutions to Sustain Freshwater - ... As Villiers (1999) mentions, “a desalination project for 10,000 people costs the equivalent of one military tank; for 10,000 people, the price is roughly that of a jet fighter” (p.334). Coupled with the cost, the energy will be a dilemma due to the fact that it requires a lot of energy to process. As a result, these plants will trigger greenhouse gases that are vulnerable to the environment. Energy is the big enemy of desalination, and a major barrier to its widespread implementation, and do you really want to purify water by adding greenhouse gases to the atmosphere (Villiers, 1999)....   [tags: Water Scarcity Environment]

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 & Sherman 1976; Wittenberger 1981)....   [tags: Biology ] 976 words

The Effect of Global Warming on The Netherlands - On the coast of the North Sea, west of Germany and north of Belgium, sits the Netherlands. This country is best known for windmills, tulips, cheese and clogs, and for having Amsterdam as its capital. However, this country faces great risks as sea level rises.
