Water?
As I sit in class and look around me at all the hard working students I wonder, What should I write about? The subject is water, but really, how much do I know about water? Its wet, best when chilled (much like a smooth cocktail) does wonders for my lawn but really what is water?
My gaze sharpens on the water bottle sitting to my right. The Dasani label reads ” Enhanced with minerals for a pure, fresh taste”. Enhanced with minerals? Really? What minerals I wonder? I read further, ” Minerals added for taste purified by reverse osmosis”.
Now I know that reverse osmosis is the purification of a liquuid, usually water, that through the use of pressure allows the pure solvent in a substance to pass and filters the unpure substance to not pass. The clear pure liquid that I am now drinking has been recycled? I wonder what else are we doing with water to better our society? How are we harnessing our natures resources in a manner that both improves our quality of life and also gives our Earth a little break?
Doing a little bit of research I have discovered that the most common type of renewable energy using water is Hydroelectricity. Hydroelectricity is the use of the Earths gravity on flowing or running water, using the force of the water as it hits the ground that energy is then harnessed for energy. Dams utalize this form of energy worldwide and provide 19% of the worlds electricity.
The water sitting in front of me has now taken on a whole new meaning. Not only does it refresh me and keep me happy but it also allows the world to function in a more pure way. The Earth consists of 71 % water and only a small percentage of that is usable to humans. The fresh water that we depend on is rapidly diminishing and the population of people are rapidly increasing.
