![]() Fresh water
Fresh water is one of our most important natural resources because it's needed for survival and there is no substitute for it. Unlike energy, which has many alternative forms there are no alternatives for water. Most of our earth is covered by water, but only a tiny amount is available for fresh water. The amount of accessible fresh water varies from country to country and region to region. Some regions has abundant amount of water, but many regions have shortages and this is where groundwater comes in. Groundwater is very important to these parts of the world; it is used for farming and drinking in these areas. Groundwater helps these area's tremendously and has to be used in normal quantities as they are liable to run out which causes many problems such as sinkholes, human displacement, and for soil to be totally drained of water useless for agricultural purposes. Even though tapping aquifers is a very practical idea it has some set backs as it can have disastrous effects if polluted or over used. So we have to clean the environment from harmful waste to save the fresh water from pollution. ــــــــــــــــــــــــــــــ ــــــ ــــــــــــــــــــــــــــــ ـــــ Importance of Water Water is the common name applied to the liquid form (state) of the hydrogen and oxygen compound. Pure water is an odorless, tasteless, clear liquid. Water is one of nature's most important gifts to mankind. Essential to life, a person's survival depends on drinking water. Water is one of the most essential elements to good health -- it is necessary for the digestion and absorption of food; helps maintain proper muscle tone; supplies oxygen and nutrients to the cells; rids the body of wastes; and serves as a natural air conditioning system. Health officials emphasize the importance of drinking at least eight glasses of clean water each and every day to maintain good health. Our Earth seems to be unique among the other known celestial bodies. It has water, which covers three-fourths of its surface and constitutes 60-70 wt % of the living world. Water regenerates and is redistributed through evaporation, making it seem endlessly renewable. So why worry? Actually, only 1% of the world's water is usable to us. About 97% is salty sea water, and 2% is frozen in glaciers and polar ice caps. Thus that 1% of the world's water supply is a precious commodity necessary for our survival. Dehydration (lack of water) will kill us faster than starvation (lack of food). Since the plants and animals we eat also depend on water, lack of it could cause both dehydration and starvation. The scenario gets worse. Water that looks drinkable can contain harmful elements, which could cause illness and death if ingested. ارجو ان يقدم لكم الافادة منقـــــــــــــــول |
