Water

Siphoning the Globe: Water Exhibit Exposes Worldwide Crisis

By Kelly Stewart, AlterNet. Posted January 18, 2008.


The exhibit, now at NYC's American Museum of Natural History and headed to San Diego and St. Paul, explores the depth of our global water crisis.

Editor's Note:

Water is an architect of the natural world, a building block of our bodies, and the lifeblood of our communities. It is, in short, our most important resource. And yet, each day, we squander it through pollution, mismanagement, neglect, and greed. As regions across Africa, the Middle East, Australia, Asia, and North America, face worsening drought, it is time to increase our understanding of the role of water in sustaining life for all creatures on this planet.

An amazing crew of individuals at the American Museum of Natural History in New York, led by Dr. Eleanor J. Sterling, the museum's Director of the Center for Biodiversity and Conservation have made an important contribution to halting the water crisis with their new a ground-breaking exhibit that will change how you think about water. The exhibit was also organized by the Science Museum of Minnesota, St. Paul, in collaboration with Great Lakes Science Center, Cleveland; The Field Museum, Chicago; Instituto Sangari, São Paulo, Brazil; National Museum of Australia, Canberra; Royal Ontario Museum, Toronto, Canada; San Diego Natural History Museum; and Singapore Science Centre with PUB Singapore.

The exhibit covers a huge amount of ground, including information about how other life forms interact with water, the hydrologic cycle, the history of water use across the world, virtual water facts, the effect of dams, maps of water availability and use, and a whole lot more. Presented with incredible interactive displays, you can feel, taste, hear, and see the affect of water on our lives and how important it is to protect this resource.

Sometimes my shower head drips -- I can hear the steady beat as I try to fall asleep at night. And sometimes, instead of tinkering with the temperamental shower knobs, I'll close the bathroom door to block out the noise.

Entering the new exhibition, Water: H20 = Life, at the Museum of Natural History in New York City, I was struck by a similar scene. One drop at a time, water falls from the ceiling, splashing into the others that have fallen before it. It's a hypnotic reminder that every drop is worth contemplating.

The exhibit underscores that all life on earth is founded upon water. Climate change may dominate today's environmental news, but in fact the world's supply of fresh, clean water is becoming scarce.

The World Water Council predicts that a shortage of potable water will become the next environmental crisis. Already more than 1 billion people don't have access to enough safe drinking water to remain healthy -- and the problem is expected to spread beyond Africa and Southeast Asia.

With recent reports of water troubles in industrialized nations -- from a recent oil spill off South Korea's coast to the heaps of disposable water bottles accumulating in American landfills -- the exhibit's message is timely. Interactive displays encourage participation, making the some of the more complex material both informational and fun.

The wide-ranging show is scheduled to travel worldwide after it ends its run in New York on May 26, hitting cities such as San Diego, Cleveland, Chicago, São Paulo, Canberra, Ontario and Singapore. The exhibit is intended to educate people around the world on water use and inspire them to make a difference in their communities.

In most places in the United States, we can simply turn on the tap and have immediate access to clean water. Currently, we have enough of the stuff to establish verdant golf courses in the Arizona desert and fill swimming pools in Palm Springs. Because water has historically been abundant in our country -- or at least it appears to be -- the show faces the challenge of convincing visitors that they need to be more vigilant about their personal water use.

Beginning with a section covering plant and animal life, the exhibit describes some of the remarkable ways that different species have adapted to water shortages in harsh environments. Living in arid conditions, the Texas horned lizard has ridges on its back that funnel water to its mouth. The seafaring albatross drinks salt water to survive, but it filters the salt into special glands that empty from its beak. As humans, we don't have these kinds of tricks and must rely on fresh water to survive.

I am a researcher in renewable energy, and I'd just like to touch on a couple of points from the article and head off any potential "give me a break" replies.

The figure for water consumed in the production of beef: that is actually a low figure. Cattle consume resources that require hundreds of gallons of water (per pound of meat produced.) The same is true of irrigation for some cash crops like Coffee. What has been left out is that the impact on our water supply is significantly higher due to pollution due to agricultural wastes and pesticides, and that runoff and absorption patterns are significantly altered for the worse by agricultural land development.

Also, the problem of methane release from large hydroelectric facilities is a big one, and an area of new research. What's more: while decomposition models predict that methane release should peak and subside inbetween five years and a decade, a study of American hydro power facilities has discovered that, in fact, methane is released in larger amounts than predicted from all artificial reservoirs long after that. This is an area of new study, but the preliminary results have already caused regulatory agencies to withdraw carbon-credit incentive funding from new mid-to-large hydro facilities in the US.

The quantity of methane produced by these processes is, in fact, quite extraordinary. There is some speculation of developing technology to capture it and burn it for power. And no, I have no idea how that might be accomplished.

One wrong number, on the methane. Methane's contribution to global warming is closer to 10 or 12 times that of CO2, depending on the model you use to normalize its impact. The time for which it remains in the atmosphere is significantly shorter than CO2, so it doesn't seem fair to compare it to CO2 directly by its infrared opacity, as done in the article.

(bum-rush lesson in greenhouse warming. all these gasses are transparent to light at 7000-4000A wavelength. the proof is in how you can see the mountains from your house in the burbs. if you could see in infrared 150 years ago, you could see pretty clearly. nowadays, if you could see in infrared, it would look a bit like a sea of fog. near a methane source like a reservoir, it would feel like a complete white-out. note that infrared light is synonymous with radiated heat - wavelengths 1000000-7000. Reflection and re-emission are the only ways in which our planet sheds excess heat from the sun.

the term "greenhouse" is more applicable than most people realize, as the way those work is exactly the same method. glass is transparent to visible light which hits the ground inside the greenhouse. most of this energy is absorbed, and most of that is re-emitted at a lower wavelength (infrared). the glass is now opaque to this infrared light, and reflects it back to the ground.)

There is little doubt there is a water crisis that is global in scope and regionally extremely acute. It seems also true that we do NOT have a good handle on the total system flows of water. One example: the water that is utilized in meat processing is not CONSUMED in the sense that the 600 or more gallons are not almost immediately available for other functions with or without some kind treatment including natural evaporation and rainfall somewhere. Again, having lived in Africa, i know full well what it is to have very limited access to potable water but our understanding of hydrological cycles should elevate our conversation about water usage away from the rather sensationalist use of words like consumed as if they have disappeared from the earth.

i'm already vegan but i do drink coffee... (organically shade grown fair trade as much as possible) so now coffee gotta go. how about TEA? does growing tea waste so much water?

about 2 months ago, i bought a stainless steel water bottle for 20.00---it's saved me tons of $ not buying toxic plastic bottles. carry it everywhere.

Dust Bowl - Southeast?

Living in the drought stricken southeast major metro areas, no one is talking about what we'll actually DO if or when the water runs out. There is talk about raising rates to cut use... but what if there is nothing left to use or raise rates on? What if we don't get rain... heaven forbid have another year like 2007? Do we migrate to the Great Lakes? Abondon our homes and businessses? We're not a bunch of dust bowl farmers in this region who could pick up and leave easily... what would/could/should we do?

Water and overpopulation are core issues. The rest is window dressing to distract the public.

1000 year dust bowl

This post is by James Wang, Ph.D., a climate scientist at Environmental Defense.

You may have heard about the persistent droughts in the western U.S., Australia,
and other regions. The Upper Colorado River Basin is experiencing a protracted,
multi-year drought that started in 1999. Australia's record drought is threatening
the livelihood of traditional farmers and ranchers.

At what point does a passing drought become a permanent shift to desert
conditions, and why would such a thing happen?

It can happen because of global warming. Climate change can alter global winds,
the strength and location of high and low pressure systems, and other climate
factors.

.........shortened.........Graphics and URLs omitted.

Global winds shape the Earth's climate, determining - in broad strokes - which
areas are tropical, desert, or temperate. Here's a simplified overview of how it
works.

The Sun heats the Earth most intensely in the tropical zone around the equator. The
heated air rises, cools, and then dumps its moisture as rain. That's why there are
rain forests in the tropics.

The now drier air is forced by the continuously rising equatorial air to move
towards the temperate latitudes on either side of the equator. At roughly 30° N and
S - called the "horse latitudes" - it can move no further due to the Earth’s rotation,
and settles to the surface. As the air sinks, it compresses and warms, creating hot,
rain-free conditions. This circulation pattern, called a Hadley cell, is why the
deserts of the world are located just poleward of the tropics, to the north and south.

Poleward of the desert belt, strong, high-altitude winds known as the jet streams
flow from west to east, carrying large storms with them. These mid-latitude,
temperate-region storms are an important source of rain and snow, especially
during the winter season. Much of the world's population lives in the temperate
region. It includes most of the U.S. and southern Canada, most of Europe, East
Asia, southern South America, southern Africa, and southern Australia and New
Zealand.

But climate regions aren't fixed. Several independent studies have found that
global winds are shifting due to global warming, and the shifts are faster than
predicted by climate models. Most recently is this new study in Nature
Geoscience. The tropical belt has widened by several degrees latitude since 1979.
This is consistent with other observations suggesting that the jet streams and storm
tracks have moved poleward.

The drought-stricken Upper Colorado River Basin, which includes Lake Powell, is
located just poleward of the horse latitudes at around 37° N. This has historically
been in the temperate zone, but the desert zone may be gradually encroaching upon
it. (Since nothing is simple, there are other factors contributing to this particular
drought, as well.) Similarly, water-starved Sydney, Australia at 34° S is just
poleward of the southern horse latitude.

What we may be seeing here is not so much drought as desertification - a shift in
global climate patterns due to global warming. Areas that used to be in temperate
zones may be shifting into desert, while areas that had been arid receive more
precipitation.

1000 year dust bowl again.

The drought in Atlanta will only get worse. If you want water to drink, you had
better consider moving north while you can still sell your house in Atlanta. I am
considering moving from Illinois to Canada or Alaska for the climate. Please read
"Six Degrees" by Mark Lynas. Download a summary from:
http://www.marklynas.org/2007/4
/23/six-steps-to-hell-summary-of
-six-degrees-as-published-in-the-guardian
The 1930s dust bowl is only a sample of what we are going to get with global
warming at only 1 degree centigrade. Great damage has been done, but we still
have 8 years before natural positive feedbacks lead to our extinction. Sea level
will continue to rise even if we disappear right now, but that is "minor" compared
to poison gas bubbling out of the ocean and killing almost everything.

See the chart on page 274 of "Six Degrees" by Mark Lynas. We have until 2015
to BEGIN REDUCING our total CO2 output and we have until 2050 to actually
reduce our CO2 output by 90%. The curve has to start down by 2015, not we
have to think about it by then. The peak of our CO2 production has to happen in
the next 8 years. Sorry, but we can't wait for research, no matter how interesting.
We have to implement what we know right now. The only technology we have
right now to replace coal fired power plants is nuclear power plants. I like solar,
wind, hydro, and geothermal, but all of them together cannot replace the base load
capacity of coal. Sorry, but nuclear is the only option. If we don't follow the
schedule in Six Degrees, we will encounter positive feedbacks which will take the
control of the climate out of our hands. Civilization may fall anyway well before
2050, but we can avoid going extinct by 2100, and maybe we can avoid the fall of
civilization. We have to hold the CO2 level to 400 parts per million to have a
75% chance of avoiding the positive feedbacks. We are at 380 parts per million
now. The natural positive feedbacks are explained in Six Degrees.

On the fall of civilization, read "Collapse, How Societies Choose to Fail or
Succeed" by Jared Diamond. When civilization collapses, times get really ugly.

Migratory animals face suffering, death and extinction if water sources disappear.

Many migratory animals rely on the water sources appearing where they should in a timely fashion. The way humans sap up and claim existing water resources is a wrongful lack of fairness to the wild migratory animals. Many of these animals have adapted over generations to the pattern of food and water availability. Many will not make it through relatively rapid changes in the availability of food and water.

A good movie, "Animals are beautiful people", made in 1974, showed life in the Africa for various animal people. As the water resources shortened greatly lions would guard "their" water from the remaining few creatures that hadn't migrated away. Monkeys had their secret hidden water sources. Most of the movie was happy and it caught one by surprise to see the (tear-jerking) sadness of a large flock of birds that had to abandon their young when water didn't arrive to the land when they were expected and the existing water resources had dried up. The baby birds then wandered off in huge numbers slowly dying off in the desert. I wonder how much worse things have gotten since the agricultural revolutions and subsequent desertification of many regions are sapping the water resources of the regions.
Sincerely,
Aouie

and kiss your ass goodbye. The single biggest problem facing the world today, is overpopulation. To put this in perseptive, my mother is 95 years old, in her life time the population of the earth has increased over six times. What scares me is that our politicians are so afraid of the religious right, that they won't even discuss it. Add to that the two religious loonys waiting in the wings, and as I said put your head between your legs.

Use Less

When an Ethiopian can survive on 3 gallon per day, or a European on 31 gpd, doesn't it occur to anyone reading this that 151 gpd is excessive and can be considerably reduced without threatening anyone's life?

I have lived 'off the grid' for 15 years now and I have learned a lot about my personal use of resources. I catch rainwater and use it for everything but drinking. I find I consistently use 5-10 gpd for cleaning, bathing and washing dishes (laundromat for clothes at this time) but the first thing I notice when I visit someone who has 'running' water is how easy it is to waste gallons and gallons of water without even meaning to.

I keep a pitcher of warm water full at the sink all the time, and to wash my hands I pour some into a bowl in the sink, wash, scrub and pre-rinse, then rinse with clean water. This uses about 1/4 gallon. In a situation with a sink and faucet, a person turns on the water, waits for the hot water to arrive, washes scrubs and rinses without ever turning off the faucet, and while I have never actually measured how much water this takes, it is clearly a wasteful way to accomplish clean hands. So, while nothing prevents a person with running water from filling a pitcher and using a washing bowl, it is still rarely done.

I have a composting toilet and I drip irrigate my garden. I own an incredibly water efficient front loading clothes washing machine (Equator-made in Italy) that uses 1/4 the water, soap and power of a conventional machine and I hope to have it hooked up soon. I used it for three years in a conventional situation so I know it works great.

Rainwater does not leave mineral deposits on my fixtures, it leaves your hair and body very soft, while using considerably less soap. I heat and cook with a wood stove, which also keeps water hot all the time. I never have to wait for the warm water to arrive at the faucet and when I visit a conventional home I find myself getting very annoyed that I have to either let 5 gallons run down the drain before I get to the hot stuff, or I have to plunge in and freeze my hands to save a few gallons.

In summer? I use the shower bag that campers find very convenient, or I shower in cool water, which does wonders to rejuvenate me after a hot sweaty day of work or play. I have a summer kitchen on my back porch and use a gas stove from an RV to cook.

I live in the SE US and even though we had a severe drought this year, I never had to carry water. It is surprising how easy it is to get by comfortably on less and less, without sacrificing much in the way of time or effort.

I have never thought I could live without coffee, though. I try to imagine why I would even bother to get up in the morning. So my two cups of shade grown, fair-trade OG coffee almost exactly erases my conservative efforts of moderate water use. Darn it all...
