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
