Marisa B. English Water covers nearly 70% of the Earth‚ but why is it that we are running out of water? This is possibly because only 2.5% of the Earth’s water is freshwater‚ and the rest of it is saline‚ ocean based water. People need water to survive‚ but overtime the population has increased‚ which is making it a competition to get clean water for basic necessities. Therefore‚ people should change their water consumption habits because we will run out of water and there is an over-use for

IMPORTANCE OF FRESH WATER All living things on Earth need fresh water in order to survive But human beings become ill and may even die if they cannot get pure or clean and are forced to drink polluted water. Human beings can only last 3 day without fresh water. People died of thirst after the cyclone in 1999 because their supply of fresh water from irrigation channels was destroyed form tidal waves. However water is needed for many more purposes e.g. in agriculture and industries‚ but this water

to assure the availability of clean water. The east of Egypt is bordered by the Red Sea making the option of desalination possible; however‚ the costs and adverse effects on the environment make it unappealing. A second option to be considered is water recycling. This option is cheaper and it also has a lower adverse effect on the environment. This report will analyze both desalination and water recycling techniques‚ based on cost‚ effects on the environment and social acceptance. 2.0 BACKGROUND

when increased pumping of groundwater allows saltwater pools to infiltrate freshwater supplies‚ making water unfit for human use. In response‚ cities are installing energy- intensive desalination plants‚ which require more fossil- fuel-derived power that‚ in turn‚ contributes to global warming. To date‚ desalination plants can be found in a few states and several countries. Energy Issues Keeping washing machines running also requires a great deal of fossil-fuel-supplied energy that‚ in turn
