Perrier may well be the iconic brand in the world of mineral waters. However‚ regardless of the profile of the brand‚ the company that produces the bot¬tled sparkling mineral water is having a tough time.

Water scarcity and global warming Global warming is expected to account for about 20 percent of the global increase in water scarcity this century. It is predicted that global warming will alter precipitation patterns around the world‚ melt mountain glaciers‚ and worsen the extremes of droughts and floods. Global water consumption increased sixfold in the last century - more than twice the rate of population growth - and will continue growing rapidly in coming decades. Yet readily available freshwater

“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual

How Important is Water?As we all know‚ water is essential for mankind ’s survival. However‚ people seem to believe that our water supply is endless since there is more water than land on this Earth. Water regenerates and is redistributed through evaporation‚ making it seem endlessly renewable. So why worry?Actually‚ only one percent of the world ’s water has the capability of being used by us. About ninety-seven percent is salty seawater‚ and two percent is frozen in glaciers and polar ice caps.
