It is beyond doubt that future historians will look back on our generation and the multiple water shortage and contamination problems we currently suffer from, and wonder how Western “civilization” could have advocated urinating and defecating into what little purified drinking water we have left. I apologize to the light-hearted among my readers for touching on such an apparently foul subject, but the growing global water and health crises stand in such stark contrast with current waste-management procedures, that it requires our urgent attention.
If you don’t already think that the world is nearly completely upside down and backwards, then imagine a civilization that considers those who don’t deposit their feces into a bowl of drinking water on a regular basis as miscreants, uncivilized, dirty or poverty stricken. Of course this practice is convenient for taking such refuse to wastewater treatment plants where it is processed and eventually returned to the environment, albeit in some cases considerably more contaminated with “excessive levels of nitrates, chlorine, pharmaceutical drugs, industrial chemicals, detergents, and other pollutants” than before.
This would all be fine except for three factors: water shortages, diseases borne from water contamination and fertilizer needs for boosting agricultural production. Although these are all complex and important topics deserving much more in-depth analysis, I will only briefly outline each one.
- Currently, United Nations estimates that 1.2 billion in a world of just over 6 billion people do not have access to safe drinking water. More specifically, in developing countries, 21% of all people do not have access to safe drinking water, and in rural areas the figure jumps to 30%.
- 67% of the world’s households must fetch water from outside their homes.
- Between 1990 and 1995, global water consumption rose sixfold, which is more than double the rate of population growth.
- Increasing industrialization is creating a lion’s share of the problem: it takes
300 lit resof water to produce 1 kilogramof paper, and 215,000 litresto produce 1 metric ton of steel. Changes in our diet are also driving water consumption; it takes 15,000 tons of water to produce a ton of beef, while it only requires 1,000 tons of water for a ton of grain. has approximately 21 per cent of the global population, but access to only 7 per cent of the planet’s freshwater.

Water borne diseases
- 42% of the world’s population does not have access to a latrine or other proper means of sanitation.
- “In the developing countries, 80 per cent of illnesses are water-related. Due to the shortage of safe drinking water in much of the world, there are 3.3 million deaths every year from diarrheal diseases caused by E. coli, salmonella and cholera bacterial infections, and from parasites like giardia and cryptosporidium, as well as viral pathogens like rotavirus. In fact, between 1990 and 2000, more children died of diarrhea than all the people killed in armed conflicts since the Second World War.”
- Those of us who are considered to have access to safe drinking water should consider that approximately 10 million people in the
have access to water that is not in compliance with federal standards for removal of microorganisms, and approximately 7 million Americans get sick annually from contaminated drinking water. US
Waste Management and topsoil
- Sending human excrements to waste management plants infers that they are in fact waste. Waste is any material with no inherent value that is discarded and has no further use, a completely inaccurate description of human refuse which only becomes waste upon being discarded.
- Byproducts of our digestive system, or any other digestive system for that matter, are in fact a valuable organic resource material rich in soil nutrients. It comes from the soil in the form of vegetables, fruit, nuts, or grains (and even meat), is naturally processed in the body, and then can be returned to the soil in the form of humus after careful composting to provide the highest quality soil additive.
- Returning all organic residues resulting from crop production to the soil, including animal and human residues, should be axiomatic to organic agriculture, although it is not. The profound ignorance that surrounds this topic is causing major agricultural and health problems throughout the world.
- For example, not having enough natural fertilizers has given rise to a gigantic synthetic fertilizer industry. These petro-chemical products deplete non-renewable fossil fuels, cause crop dependence, promote dangerous single crop practices, and once in the human body “interfere with the body’s normal functioning, … damage human chromosomes and cause cancer and numerous other diseases. … For example, human mother’s milk has consistently shown contamination from synthetic organic chemicals since 1951, and the incidence of human breast cancer has risen dramatically since then.”
2005 – 2015 has been denominated the International Decade for Action: Water for Life. At its launch, the UN issued a useful document entitled Water for Life: Making it Happen. In it, they dramatically emphasize the importance of improved water and sanitation services:
“Improved water and sanitation will speed the achievement of all eight MDGs, helping to:
· eradicate extreme poverty and hunger;
· achieve universal primary education;
· promote gender equality and empower women;
· reduce child mortality; improve maternal health;
· combat HIV/AIDS, malaria and other diseases;
· ensure environmental sustainability; and
· develop a global partnership for development.”
Given this emerging reality, it is little wonder that water has been described as “the oil of the twenty-first century”, a scarce commodity that will be a source of conflict between peoples and nations. This is fine but oil shortages can be resolved by developing alternative energy sources, while the water supply cannot be increased other than by desalinization, a costly and complex process.
The United Nations proposes a complex set of interrelated actions to combat this crisis. A major limitation in advocating flush toilet systems for everybody, besides those mentioned above, is their prohibitive cost for nearly every country around the globe. Because of this, and because this is considered the only civilized solution, governments simply leave the problem unresolved, leaving 90 per cent of sewage and 70 per cent of industrial wastes in developing countries to be discharged into water courses without treatment.
However, in his insightful book “The Humanure Handbook”, Joseph Jenkins clearly demonstrates that composting humanure as he denominates it, is the most accessible, viable and expeditious option for resolving the sanitation quandary and its host of accompanying problems. His many years of personal experience and research indicate that although raw humanure “carries with it a significant potential for danger in the form of disease pathogens,” … they are completely destroyed by composting when the retention time is adequate or when the composting process generates enough internal, biological heat. Both of these conditions are easily met when the compost heap is properly managed.
Spreading the resulting humus over his garden for 25 years has also proven that the product is an effective source of fertilizer for agriculture destined to human consumption. In fact, it may be useful to provide just a short list of the benefits of the humus that results from compost: enriches soil, prevents pollution, fights existing pollution, restores land, destroys pathogens and saves money. I am an avid composter (although admittedly not of my humanure) and would like to add here that perhaps the most beneficial aspect of compost is the sense of self worth and satisfaction one feels when helping organic elements complete their natural cycle and become dirt again.
Of course setting up composting systems that can meet sanitation needs for the 1.2 billion excluded human beings (and eventually the rest of the entire human population), especially in urban settings, would be a daunting task to say the least. However, the progress made towards providing safe water supplies and sanitation services for the world’s poor over the past decade or two (according to the UN, 83 per cent of the world's population used improved drinking water sources in 2002, up from an estimated 79 per cent in 1990) pales shamelessly with the overwhelming and ever increasing need.
All true change comes hard. Changes of this magnitude, requiring rethinking such deeply entrenched ideas about civilization, come even harder than normal. However, we can resist our intuition and permit nearly half of the world’s population to live in conditions that anybody reading this would consider horrifying, or we can explore thorny but promising paths towards true sustainability and dignity. If doing this single action well helps us make huge strides towards attaining all eight Millennium Development Goals, and thus bringing prosperity to the world’s people, I suggest we explore that path without further adieu.
