I have that old Joni Mitchell song playing in my head ever since reading about the ways we are destroying our last fresh water supplies. Probably a good thing, I need to have reminders like this to remember that warm water pouring over my head in the shower comes at a greater cost then the pittance we pay for it represents. Yet, let's be certain that the major players in water waste has to be industry, especially the agricultural industry.
Yeah, I've been reading Blue Gold (Maude Barlow & Toni Clark) in preparation for a paper I'm doing on the ethics of bottled water. It is so easy to ignore the basic facts of our situation. We simply don't want to think about it. Like Joni says, "you don't know what you've got til its gone." This makes me both sad and angry, especially at my complicity in this whole mess.
Studies have shown that simply by laying down pavement we are depleting the total sum of available fresh water on our planet. Water is not able to trickle down into the aquifers, instead we redirect it into rivers which take it out to sea where it becomes salinated, usable only at great energy cost which compounds the problems. Energy use is implicated in the overall warming of our planet which is decimating the great polar caps and glaciers at an alarming rate. For those who think the water levels won't rise, remember much of this mass of ice is over land (Greenland for instance) and will affect the sea level - don't take my word ask a Vanuatian. Sea water also intrudes on the sea coast aquifers we are draining faster than nature can replenish, this is a big problem because we absolutely need fresh water to survive.
So as I dried off from my costly shower, I made myself a coffee and came down to type this up on a computer (the IT industry is very water wasteful) and remember that my body is mostly made up of water! Something to think about.
