The better aware we are, the better we understand our surroundings. Water is an element that drastically impacts our surroundings and is a shared commonality found across the globe. “Humans need water to live, plain and simple”.¹
How long can the average healthy human live without water? Roughly 3 to 5 days .¹ With only 3% of readily available fresh water and a growing population, we need to take an active stance in water conservation and become more aware.²
The Worlds Water
As we begin to discuss water, view earth as a “closed system,” like a terrarium.² “That means that the Earth neither, as a whole, gains nor loses much matter, including water”. ² It moves continuously around, throughout, and above the Earth in the form of water vapor, liquid water, and ice.² Research has revealed that some of the same water that existed on Earth millions of years ago is still exists on Earth today.² With its many forms, water should be considered a driving force for most forms of conservation.
The figure to the left shows all of the earth’s water (liquid, ice, freshwater, saline) if it were condensed into a sphere.² The water sphere would have a diameter of about 860 miles, ranging from Salt Lake City, Utah to Topeka, Kansas, USA. ²It would have a height (towards your vision) of 860 miles high as well, so still a huge amount of water.² The true value of this image is to image that only 3% of the sphere is readily available drinking water.² From recycling to gas emissions, conservation as a whole actively benefits water conservation.
