Class: AE3B WATER SCARCITY : A TIME-BOMB IS ABOUT TO EXPLODE People can survive at least ten days without eating. But without water‚ they will die after only three days. It shows how important water is in people’s daily life. So‚ just imagine how we survive if there’s not any water available. That’s the reason why water scarcity is one of the key environment issues of our time. This essay will identify some major causes and offer three solutions. The shortage of water resources is mostly caused

to tell about WATER water is the most imp thing on earth.without water no life.We take it for granted‚ we waste it‚ and we even pay too much to drink it from little plastic bottles. And still‚ today‚ nearly 1 billion people in the developing world don’t have access to it. Clean‚ safe drinking water is scarce. It is the foundation of life‚ a basic human need. Yet today‚ all around the world‚ far too many people spend their entire day searching for it. Simply put‚ water scarcity is either

salt water is that both are basically the same chemical - water‚ although the contents of other materials dissolved in it differ. Both contain some amount dissolved chemical in it though the quantities vary. Both form different links in the water cycle of the nature. Both are homes to aquatic life. Difference: Salt water contains much higher quantities of dissolved chemicals as compared to fresh water. This higher concentration of chemical also raises the density of salt water above

thank god for keeping me calm with all the stress I had. Abstract The purpose of my project is to explain the processes of the water cycle‚ explain what it is‚ and to show the process of evaporation and what happens during this process.my procedure consist of placing the small container in the middle of the large ‚ clear bowl. Fill the bowl with a little water‚ being careful not to fill the small container inside. Cover the bowl with plastic wrap‚ and fasten the plastic wrap around the rim

Water is an integral part of land/soil productivity. Its misuse can cause both degradation and erosion of soils. Management of water resource is considered to necessary for well being of human life as well as crop yields. There is a gap between the seasonal availability of water and its equitable supply throughout the year. Accordingly the storage of water and passage through soils is very important. It is well known that about 70% area in this country is subject to varying degree of water stress

Business Opportunity Originated‚ Screened and Confirmed Viable: Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater)‚ also known as Desalting or Desalinization. In addition to the removal of minerals‚ the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s

Water supply and sanitation in Bangladesh is characterized by a number of achievements and challenges. The share of the population with access to an improved water source was estimated at 98% in 2004‚[1] a very high level for a low-income country. This has been achieved to a large extent through the construction of handpumps with the support of external donors. However‚ in 1993 it was discovered that groundwater‚ the source of drinking water for 97% of the rural population and a significant share

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even
