With water a VERY hot topic in California right now, I thought I’d make an Encore post of a Blog I wrote on water back in June 2012. Enjoy.
Water Efficiency – An interesting aspect of the “green” movement.
Today I’m going to talk about Water Efficiency.
I find water efficiency one of the more interesting aspects of the “green” movement. First, unlike coal, natural gas or most other natural resources, the supply of water is actually unlimited. And it keeps getting made every day. Second, and probably most important, we actually NEED the stuff to survive. You could make an argument that we couldn’t “survive” as a modern society without the other supply-limited natural resources we’ve grown to rely on in everyday life, but without water we actually CAN’T survive. Our bodies need it to function.
So why do we need to be efficient with an unlimited resource?
The answer to that question is its the procurement and delivery of water that causes the issue. As I said, there’s enough water on the planet to take care of our needs… plus more gets made every day. Actually it recycles itself in a never ending circle whereby even the water we use today ends up falling out of the sky at some point in the future, available to be “used” again. The crux of the issue is it doesn’t always fall out of the sky or end up in the places where we need it the most. At least not today. Before modern civilization, humans ALWAYS chose to live where there’s water. After all our bodies need it to survive and before modern technology made it possible to get water where we want it, if you weren’t close to it, you didn’t last very long. Now that we’ve figured out how to procure and deliver it pretty much wherever we want it, we’ve been able to live in areas of the world that actually have no source of natural water, or a source so small it limits how much growth can occur without modern technology.
At the end of the day the simple answer is that growth of any kind is limited by the amount of water, or more realistically the access to an amount of water, necessary to sustain the population. Especially since the population NEEDS the water for their own biological survival. The more efficient we are with the use of water, the more growth that a given city, state, nation, whatever, can support. As the population grows and the demand for water increases, it’s obvious that if you don’t become more efficient with the use of that water, over time that population will need more water. The cost of procuring and delivering water to a given population, especially one where water isn’t naturally abundant, can be enormous. And sometimes physically impossible. Becoming more efficient with the use of water becomes a necessity, not an option.
Until next time
