Water the means to life,do not throw it away!
Water is so necessary, but potable water is NOT a tradable commodity like oil nor is its scarcity the topic of many headlines. All life on Earth needs water to survive and grow; we don’t “need” oil.
Maybe we take it for granted because nature gives us a “free” supply in the form of rain, glacial runoff and underground aquifers that don’t require much to tap into. But what if that supply becomes tainted?
Water covers about 70% of the Earth’s surface, most of it being salt. Freshwater is available, but very limited in comparison, especially in certain areas… and not all of it is drinkable. Fresh water is found in a few places on Earth:
- Ground sources such as groundwater, hyporheic zones and aquifers make up about 1.6% of the total water found on Earth.
- Precipitation, which includes rain, hail, snow, fog, etc., equals about .001% of total water on Earth.
- Surface water such as rivers, streams, glaciers is about 3%.
Less than 5% of our total water supply is fresh water. Now there are some new technologies that are changing that. We can also get clean fresh water through desalinization. A Jan. 17, 2008, article in The Wall Street Journal stated that “Worldwide, 13,080 desalination plants produce more than 12 billion gallons of water a day.”
While that may seem like there is a large amount of drinking water available, consider the facts:
- The average human needs about two quarts per day of drinking water to survive.
- The World Bank estimates the global population to be about 6,775,235,741. (As of the end of 2009.)
- This means that we need to consume at least 13.5 billion quarts of water daily, which is the equivalent of 81
million barrels a day. (Oil barrels, fluid barrels would be even more.)
According to the CIA, the world consumes over 96 million barrels of oil per day – just a bit higher than the bare minimum drinking water humans on Earth need to survive. The reality is that it takes about 3,000 liters of water, converted from liquid to vapor, to produce enough food to satisfy one person’s daily dietary needs, not including all the other things we use water for (showers, toilets, etc).
Using those figures, our daily demand is more like 121 BILLION BARRELS per day, which dwarfs the amount of daily oil usage. That is a serious commodity.
“Water, we can not live without it, and we miss-use it, do not respect it, and assume it will always be there for us. Let the human race wake-up before there is no more water!” Hotdogfish!
