With the changing of the season so obvious where I live – especially the beauty of the leaves on trees turning yellow, orange, red and brown amongst the greens, the cycles of nature are front and center in my mind. Also, water has been on my mind. There is the melting of polar and glacial ice, the appearance that storms are increasing in their intensity, drought in some areas leading to large and intense wildfires and just having enough clean and safe drinking water for the burden of humanity.
For too long, humankind has treated the Earth as though it was a supermarket of resources to be tapped, extracted and exploited for profitable gain and usage. When I was growing up in the El Paso TX desert area, the Rio Grande always had water flowing. One year not too long ago, there was only dry river bed. Because Nature is not static, water levels are always changing. The amount of snow in the Colorado Mountains in winter or the release of excess water by the Mexican government preparing for “flood season” can greatly change the flow of the Rio Grande from one year to the next or from one week to the next. In my early adulthood, I once saw a girl drown in that unpredictable river.
On our own farm, the farm pond and beaver ponds can be full and overflowing in Springtime and dry and minimal this time of year. These are all reflections of the natural cycles of nature and water and we would do well to learn to understand them and cooperate with them, rather than fighting against nature or polluting the little fresh water the planet actually has available. We are a “water” planet which is crucial to all of life.
Water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. However, 96.5% of all the Earth’s water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact. If you could melt all that ice, and the Earth’s surface was perfectly smooth, the sea levels would rise to an altitude of 2.7 km. For those like me who don’t do metric easily that is a rise of almost 9,000 feet or over 1-1/2 miles. Wow !!
The amount of water that exists as groundwater, rivers, lakes, and streams is only a little over 0.7% of the planet’s total water resources. It is a much rarer and more precious commodity than most people are aware it is as they flush their toilet, water their yards and fill up their drinking container.
Water has many forms which most of us are intimately familiar with — rain, hail, snow, ice, steam, fog and dew. Even though the minerals in salt water are harmful to most land plants and animals, it is from these vast salty reservoirs (the seas and oceans) that most of our precipitation (rain, snow, etc) rises up to form clouds and comes down upon the land and flows back into the ocean again. The water, or hydrologic, cycle never ends. That is a good thing.
Each person needs about a gallon a day for drinking, cooking, and washing. The average water usage in medieval times was no more than 3 to 5 gallons a day per person. Presently in the United States, people are using about 1,500 gallons a day for their needs and comforts which does include recreation, cooling, food production, and industrial use related to their existence. Another Wow !!
I have been aware for a long time that there are concerns about enough fresh water for the planet’s growing and evolving population. Long ago, Leonardo da Vinci acknowledged that water is the driving force of all nature. In many places on this planet reservoirs and aquifers are drying up. Currently, one in seven people on the planet lacks access to safe drinking water. In some places in the Middle East water has become more important than oil and governments invest in desalination plants. Up to 75% of the farmers in the hot dry plains of northern India, eastern Pakistan and Bangladesh intensely irrigate their crops with pumped groundwater and their use of that water is intensifying.
The Intergovernmental Panel for Climate Change predictss that the fraction of global population experiencing water scarcity is destined to increase throughout the 21st century. More and more, people and nations will have to compete for those water resources. Jean Chrétien, former Canadian prime minister and co-chair of the InterAction Council, admits that “Using water the way we have in the past simply will not sustain humanity in future.”
So what can be done ? As far back as 2010, 1200 leading international experts from 80 different countries came together and created a list of 19 partial solutions to the Freshwater challenges facing humanity. Of course raising consumer awareness and teaching how to make better use of limited water resources tops the list and is why I am writing a blog about this today. I always seek to be part of “the solution” to whatever concerns me rather than part of the “problem” which only leaves one mired in disfunction.
Wastewater treatment is an obvious place to conserve and revitalize the water that exists. Advanced technologies for cleansing wastewater continue to progress and develop refinements. Clearly agricultural and irrigation practices need rethinking. 70 percent of the world’s freshwater is currently used for agriculture. Water needs to be revalued at higher prices which would reduce waste and pollution. One way to conserve fresh water is to improve the catchment of water running off paved surfaces in urban areas.
Good water management takes into consideration the whole ecosystem – sewage treatment plants could be operated in partnership with clean energy producers who use the wastewater to fertilize algae and other biofuel crops. Those crops, in turn, have an ability not only to soak up nutrients but purify the wastewater which can reduce pumping and treatment costs.
Yemm & Hart’s Origins Material uses recycling water that is heated and sent through piping to melt the recycled post-consumer plastic flakes and pellets loaded into the trays of our press. Then, recycling cool water is sent through pipes to set the material into the patterns that make Origins unique. It is the melting flow of plastic which then is “frozen” into place that gives us a random and natural patterning effect.
What’s new with the most “ECO” of all materials ? (Yeah, I’m talking WATER) I believe that what’s new is a developing but radical change in humanity understanding not only the precious nature of this natural resource but regarding each person’s role in conserving and protecting it’s life sustaining qualities.
Think about it the next time you take a thirst-quenching drink of pure, clean water.

Water !! There is nothing more precious to life on Earth. Almost as precious however are the youth who will inherit the Earth when their elders are no longer the driving force of progress and evolution.
I stumbled upon the story of one such young man, Steven McDowell, with a vision for helping to alleviate the drought conditions that have become frequent news items in the southwest over to the west coast. California is currently in one of it’s worst drought cycles ever. Steven realizes that – “With climate change affecting our rain patterns we must now plan for the possibility of living with far less annual rainfall, so saving every drop could be essential.”
As this 14 year old began doing research for his science fair project, using California’s drought as his subject and how to help solve it with a focus on how each person could do their share by preserving and storing as much water as possible, he was not able to find suitable storage options already existing that would fulfill his personal goals.
So, he started thinking outside of the box to come up with a completely different solution. He took a walk around his neighborhood. What did every house have in common ? In a moment of inspiration, the answer to that question became the seed for his new idea. Every house had a fence around their yard and “for the most part they all were made of the same thing…wood”. Steven goes on to say – “I had an idea; what if the fence around my yard could be used to collect runoff rainwater!”
So he did an internet search for an existing fence product that could accomplish that goal but he found nothing like it at all. He started doing his theoretical calculations using his own yard’s fence which was 80 feet by 70 feet by 80 feet. At six feet high by seven feet long and making his “idea” fence slightly wider than his actual, 12 inches, he determined that each fence section could hold approximately 320 gallons.
Next Steven calculated how much rainwater run-off he could capture from a 2,000 sq ft roof surface area using a rainfall total of 1 inch times his conversion factor. He determined the rainwater run-off would equal around 1,200 gallons of water. The fence would capture and evenly spread that run-off water to each storage unit whenever it rained. Thus he realized that he could theoretically hold almost 13 thousand gallons of fresh pure rain water in such a fence structure.
It is not surprising to learn that Steven won 1st Prize at his science fair with the mock-up of his working Water Fence idea. Steven explains how he realized that he was onto a truly important product idea – “My engineering teacher stated it was the best original idea he had seen in 14 years of science fairs and my science professor told me to patent the idea right away, which I did. Three of the judges approached me as well and asked me to install it in their homes immediately.”
Steven McDowell has gone on to win many other prizes with his Water Fence idea as well including the U.S Stockholm Junior Water Prize Regional Award and the American Meteorological Society’s “Certificate of Outstanding Achievement”. Even as he is very excited that his incredible Water Fence system made of HDPE (High-Density Polyethylene) which is 100% recyclable (yes, Steven is saving trees that would have been wooden fences as well as conserving fresh water !!) will soon be available for purchase, he also encourages others to create sustainable options for water conservation. The importance of water can not be over-stated.
Scientist’s predict that by 2050 half of the world’s population will be impacted by a scarcity of fresh water. Environmental refugees will be forced to migrate away from areas without the necessary resource of water. The current mismanagement and misuse of increasingly scarce water resources threatens to plunge most of the global population into extreme water poverty according to the world’s leading water scientists.
The draining of rivers and underground aquifers as well as pollution and erosion along with climate change pose a long-term threat to human welfare. The increasing use globally of water combined with the permanent degradation of quality in existing water supplies is on an “unsustainable trajectory” according to scientists who feel it is fast approaching a global tipping point.
Our world needs more kids like Steven McDowell and I believe they are out there dreaming up solutions to the challenges that face mankind as we move into a future we can only theorize about now. I remain optimistic that the vitally precious resource of imaginative kids will not only find solutions to a potential scarcity of fresh water but the other pressing issues to affect everyone’s quality of life.
