Will Global fresh water be shortage in 20 years?

Delvin

Liquid freshwater, which is used as the primary supply of drinking water, constitutes a very small fraction of the water on the planet.

Due to issues like climate change, poorly managed water usage, agricultural irrigation practices, and population growth, the sustainability of water resources has now become an important issue globally.

The expected increase in the total production of human and animals feces (due to population growth and meat consumption), is bound to have a detrimental effect on microbial water quality in both coastal and inland waters of developed countries.

 It said that global fresh water will be very shortage in 20 years, and at that time, the water will put on rations. 

And the next  target will be air, because of population leap and green plant decrease such forests decrease.

Is it terrible and incredible?

Re: Will Global fresh water be shortage in 20 years?

If more people stopped using reverse osmosis and softeners for their drinking/house water, there would be huge water savings (not to mention no harmful chlorides going into the environment).

Reverse osmosis wastes 3-4 gallons for every gallon it produces. That is an enormous amount of water waste, and not something the purveyors of RO like to talk about.

Water Softeners waste water regenerating. For an average family of 4, the amount of wasted water is 2-3 regerations per week at 50 gallons each. Doing the math - that's 100 - 150 gallons of wasted water per week.

There are other environmental issues with water softeners. Chlorides, for one. Whether your softener is potassium or salt, chlorides are sent to the sewage treatment plant - which is not capable of removing them. The effluent released from the sewage treatment plant raises the chloride level in rivers and lakes - upsetting the ecological balance and affecting sensitive crops. Another problem with softeners is the servicing needed. How about the wasted fuel/increased emissions from that monthly servicing of your softener? not good.

Technology exists to solve hard water problems without the wasted water, endless bills, endless servicing and environmental harm that the RO/water softener combination offers. Copper ionization will transform the structure of the minerals so that they no longer cause hard water scaling problems. Pair that with a state-of-the-art mixed media filtration tank and you have the solution. You get clean water from every faucet, no water waste, no hard water problems and no softener. Perfect for septic tanks and ideal for well water as well as municipal sources.

Ah-ha... I didn't get that from the other post...

So this system precipitates some of the Ca & Mg ions out onto the Cu electrodes???

And then what a little activated carbon to adsorb the anions? 

I still think it's more wishful thinking than actual results, how much stuff can a 2 ft pipe remove with water flowing through at 20 ft/second?  Especially given that the power supply looked like a little wall-wart <50Watts.

ATLANTA — It's raining again in the Southeast. Much of the drought-parched region has been deluged recently by winter downpours, including weekend storms that battered the downtown business district and a swath of north Georgia.
The drought has not ended, but it has eased across most of the region, according to the U.S. Drought Monitor and the National Weather Service.

Lake Purdy, the main drinking water supply for Birmingham, Ala., is at normal levels for the first time in almost a year. From Jan. 1 through Sunday, Birmingham received 12.09 inches of rain, just below the average of 12.78.

Some Alabama farmers are finding fields too wet to prepare for spring planting. North Carolina dropped recently from 39 to zero counties in the worst category of drought.

Here in Atlanta, where stark pictures of a drier-by-the-day Lake Lanier pushed the drought into the national spotlight last fall, the drought is essentially over, says Pat Stevens, chief of the environmental planning division of the Atlanta Regional Commission.

Sadly, it is an inevitability. We are already seeing major shortages everywhere. Both Las Vegas NV, and Las Vegas NM found themselves embroiled in lawsuits from surrounding counties over water rights, and it won't be long before other cities find themselves in similar situations.

"The amount of fresh water available for human use is less than 0.08% of all the water on the planet. About 70% of the fresh water is already used for agriculture, and the reports say that the demands of industry and energy will grow rapidly. The World Water Council report estimates that in the next two decades the use of water by humans will increase by about 40%, and that 17% more water than is available, will be needed to grow the world's food supply. The commission concludes "only rapid and imaginative institutional and technological innovation can avoid the crisis".   -- Excerpted from the BBC News-March,2000.

 

It's not all doom and gloom however. The good news is there are innovative companies producing eco-friendly products that help the environment, reducing consumption of our precious resources. There are even waterless technology products that preserve our water supply, empowering consumers to make a difference. One such product, Eco-SheenTM allows us to save millions of gallons of water per day, without doing any harm to the ozone layer.

We are already short of fresh water. The water table in Arizona drops one meter every year. Lake Meade water level is 30 meters below full for the past 5 years. Sediment in the Great Lakes is polluted with PCBs. Canada's tar sand project produces 6 barrels of toxic water for each barrel of oil recovered. 80% of China's rivers are dead from raw sewage. - and the world population will increase by about a billion.

We can however turn salt water into fresh and squeeze condensate out of the air. It just requires energy.

And that's the real problem. Eventually we will exhaust our supply of cheap fuel. It really doesn't matter whether we have reached "Peak Oil" or not because ---supply can not keep up with demand (China increased inport of crude oil this year by 11 %) but that doesn't matter because --- oil exporting countries are starting to keep it for their own growth, but even that doesn't matter because ---- as Charlie Hall has noted from his observations, the EROI (energy return on investment) is diminishing.

In the beginning we used one barrel of oil to recover 100 barrels. We now only recover 10 That's an EROI of 10:1 As we approach an EROI of 1:1 the quantity of oil we have in reserve becomes irrelevent. We need an EROI of 5:1 to maintain the complexity of our civilization and all the future sources of energy are lower than this. We need to learn very quickly how to be much more energy efficient so that we can survive on alternate energy.  Our present economy runs on oil.

While I really don't thing we're at any risk of running out of water.  Will there be shortages? Yes. There are already... But...

What it will do is to put pressure on other technologies.  Israel farms the Negev desert.  How? With seawater.

We'll do the same thing.  Will the low margin mid western farms still be able to irrigate the same wasteful way they do today? Nope!

Will we continue to believe we can grow corn-ethanol? I hope not. 

Will we adopt solar energy?? Gee there's a no-brainer!

Re: Will Global fresh water be shortage in 20 years?

clean fresh water is critical NOW.  Check the water in your area. In 20 years at this rate we won't be around to talk about it.

There is so much mercury in the water from coal fired power plants that no one can eat the fish. Many farms can no longer survive becuase their wells and water supply is dried up or gone bad.

Oil spills are happening every week. The Exxon Valdez was not even the biggest.

Power plants that run on Fossil Fuels use a large amount of water to make electricity. About 1 gallon for every KWh of AC.A Nuclear plant used 50% more than any other fuels.

Animal farms use 60% of the drinkable water for live stock each year. Their waste also creates some of the most harmful greenhouse gases, methane !

Re: Will Global fresh water be shortage in 20 years?

I read somewhere that every year we spill 16X as much oil as the Valdez spilled.  I suspect that includes all those WD30 spray cans.

Another good reason to go electric.

Delvin,

Could you cite your information or present a factual base. As there are already freshwater problems in some areas on the globe, troubled waters are here and now.

I think it is neither terrible or incredible, inevitable maybe, if we don't make changes to ensure water quality now. Contact your law makers and representatives, let your voice and opinion be known.
