Critically Acclaimed New Book Investigating The Enormous Amounts Of ‘Hidden’ Water We Consume Every Day
It takes more than 7,600 liters (2,000 gallons) of water to make a single pair of jeans. That morning cup of coffee required 140 liters (37 gallons) of water before it found its way to your table—water that was used to grow, process and ship the coffee beans. When we spend money on food, clothes, cellphones or even electricity, we are buying water — a shockingly large amount of water.
Your Water Footprint provides essential information to reduce your water use which will help you save money, be prepared for shortages and ensure our children and grandchildren will have abundant fresh water. Water-wise choices is all about smart substitutions and changes, rather than sacrifice and self-denial.
“Most countries are simply not ready. They do not have policies to protect the rights of local and indigenous peoples, to determine land tenure or even work out who owns the ‘carbon rights’ to a forest,” Larson told participants at an international conference on smallholder and community forestry in Montpellier, France, in late March.
Under the REDD initiative, richer countries would pay to maintain forests in tropical regions to offset…
The water footprint of a half-litre bottle of water is 5.5 litres – yet well over a billion people live in areas with chronic scarcity
By Stephen Leahy
I have a confession: I knocked back 320 pints at the pub last night. I actually only had two shots of a decent single malt but it took 320 pints of water to grow and process the grain used to make the whisky. That’s a whole lot of water considering the average bathtub holds 60 to 80 litres.
Even after 20 years of covering environmental issues in two dozen countries I had no idea of the incredible amounts of water needed to grow food or make things. Now, after two years working on my book Your Water Footprint: the shocking facts about how much water we use to make everyday products, I’m still amazed that the t-shirt I’m wearing needed 3,000 litres to grow and process the cotton; or that 140 litres went into my morning cup of coffee. The rest of my breakfast swallowed 1,012 litres: small orange juice (200 litres); two slices of toast (112 litres); two strips of bacon (300 litres); and two eggs (400 litres).
Water more valuable and useful than oil
Researching all this I soon realised that we’re surrounded by a hidden world of water. Litres and litres of it are consumed by everything we eat, and everything we use and buy. Cars, furniture, books, dishes, TVs, highways, buildings, jewellery, toys and even electricity would not exist without water. It’s no exaggeration to say that water is far more valuable and useful than oil.
A water footprint adds up the amount of water consumed to make, grow or produce something. I use the term consumed to make it clear that this is water that can no longer be used for anything else. Often water can be cleaned or reused so those amounts of water are not included in the water footprints in the book. The water footprint of 500ml of bottled water is 5.5 litres: 0.5 for the water in the bottle and another five contaminated in the process of making the plastic bottle from oil. The five litres consumed in making the bottle are as real water as the 500ml you might drink but hardly anyone in business or government accounts for it.
The incredible amounts of water documented in Your Water Footprint are based primarily on research done at the University of Twente in the Netherlands, where Arjen Hoekstra originated the concept of water footprints. The amount consumed to make something varies enormously depending on where the raw materials come from and how they are processed. Wheat grown in dry desert air of Morocco needs a lot more water than wheat grown in soggy Britain. For simplicity, the amounts in the book are global averages.
One of the biggest surprises was learning how small direct use of water for drinking, cooking and showering is by comparison. Each day the average North American uses 300 to 400 litres. (Flushing toilets is the biggest water daily use, not showers.) 400 litres is not a trivial amount; however, the virtual water that’s in the things we eat, wear and use each day averages 7,500 litres in North America, resulting in a daily water footprint of almost 8,000 litres. That’s more than twice the size of the global average. Think of running shoes side by side: the global shoe is a size 8; the North American a size 18. By contrast, the average water footprint of an individual living in China or India is size 6.
Peak water is here
Water scarcity is a reality in much of the world. About 1.2 billion people live in areas with chronic scarcity, while 2 billion are affected by shortages every year. And as the ongoing drought in California proves, water scarcity is an increasing reality for the US and Canada. Water experts estimate that by 2025 three in five people may be living with water shortages.
While low-flow shower heads and toilets are great water savers, the water footprint concept can lead to even bigger reductions in water consumption. For example green fuels may not be so green from a water consumption perspective. Biodiesel made from soybeans has an enormous water footprint, averaging more than 11,000 litres per litre of biodiesel. And this doesn’t include the large amounts of water needed for processing. Why so much water? Green plants aren’t “energy-dense,” so it takes a lot of soy to make the fuel.
Beef also has a big footprint, over 11,000 litres for a kilo. If a family of four served chicken instead of beef they’d reduce their water use by an astonishing 900,000 litres a year. That’s enough to fill an Olympic size pool to a depth of two feet. If this same family of opted for Meatless Mondays, they’d save another 400,000 litres. Now they could fill that pool halfway.
We can do nearly everything using less water. It’s all about smart substitutions and changes, rather than sacrifice and self-denial, but we can’t make the right choices unless we begin to see and understand the invisible ways in which we rely on water.
We learn in elementary school that water is in a constant cycle of evaporation and precipitation, making our crops grow and flowing from rivers into oceans. While the amount of water on Earth remains fairly stable, its distribution around the globe is changing, and this change is being accelerated by human activities.
A new book, “Your Water Footprint,” by environmental reporter Stephen Leahy, takes a close look at the “virtual water” that surrounds us in everyday life. This isn’t just the water we use to boil pasta or take a shower, it’s the water that’s used to grow our coffee beans and power the local energy plant. As the demand for this kind of water increases, the more threatened our access to fresh water becomes. At the same time, pollution makes vast amounts of water unusable.
I had the opportunity to catch up with Leahy over Skype.
TreeHugger: What were your goals for writing this book?
Stephen Leahy: To help people understand this other aspect of water that we use, that we don’t see. This virtual water concept: the water it takes to make things, the water it takes to grow our food, to make our products, to make our clothing. This is that unseen water that we don’t think about, and because we don’t see it, we’re not really aware of it.
It’s an enormous amount of water that we end up consuming every day without realizing it.

The world’s last remaining forest wilderness is rapidly being lost – and much of this is taking place in Canada, not in Brazil or Indonesia where deforestation has so far made the headlines.
A new satellite study reveals that since 2000 more than 104 million hectares of forests – an area three times the size of Germany – have been destroyed or degraded.
Since 2000 more than 104 million hectares of forests – an area three times the size of Germany – have been destroyed or degraded.
“Every four seconds, an area of the size of a football (soccer) field is lost,” said Christoph Thies of Greenpeace International.
The extent of this forest loss, which is clearly visible in satellite images taken in 2000 and 2013, is “absolutely appalling” and has a global impact, Thies told IPS, because forests play a crucial in regulating the climate.
The current level of deforestation is putting more CO2 into the atmosphere than all the world’s cars, trucks, ships and planes together, he said, adding that “governments must take urgent action” to protect intact forests by creating more protected areas, strengthening the rights of forest communities and other measures, including convincing lumber, furniture manufacturers and others to refuse to use products from virgin forests.
Greenpeace is one of several partners in the Intact Forest Landscapes initiative, along with the University of Maryland, World Resources Institute and WWF-Russia among others, that uses satellite imagery technology to determine the location and extent of the world’s last large undisturbed forests.
The new study found that half of forest loss from deforestation and degradation occurred in just three countries: Canada, Russia and Brazil. These countries are also home to about 65 percent of world’s remaining forest wilderness.
However, despite all the media attention on deforestation in the Amazon forest and the forests of Indonesia, it is Canada that has been leading the world in forest loss since 2000, accounting for 21 percent of global forest loss. By contrast, the much-better known deforestation in Indonesia has accounted for only four percent.
Massive increases in oil sands and shale gas developments, as well as logging and road building, are the major cause of Canada’s forest loss, said Peter Lee of Global Forest Watch Canada, an independent Canadian NGO.
A big increase in forest fires is another cause of forest loss. Climate change has rapidly warmed northern Canada, drying out the boreal forests and bogs and making them more vulnerable to fires.
In Canada’s northern Alberta’s oil sands region, more than 12.5 million hectares of forest have been crisscrossed by roads, pipelines, power transmission lines and other infrastructure, Lee told IPS.
Canada’s oil sands and shale gas developments are expected to double and possibly triple in the next decade and “there’s little interest at the federal or provincial political level in conserving intact forest landscapes,” Lee added.
The world’s last remaining large undisturbed forests are where most of the planet’s remaining wild animals, birds, plants and other species live, Nigel Sizer, Global Director of the Forest Programme at the World Resources Institute, told a press conference.
Animals like Siberian tigers, orangutans and woodland caribou require large areas of forest wilderness, Sizer noted, and “losing these top species leads to a decline of entire forest ecosystems in subtle ways that are hard to measure.”
While forests can re-grow, this takes many decades, and in northern forests more than 100 years. However, if species go extinct or there are too few individuals left, it will take longer for a full forest ecosystem to recover – if ever.
Trees, plants and all the creatures that make up a healthy forest ecosystem provide humanity with a range of vital services including storing and cleaning water, cleaning air, soaking up CO2 and producing oxygen, as well as being sources of food and wood. These ‘free’ services are often irreplaceable and generally worth far more than the value of lumber or when converted to cattle pasture, said Sizer.
In just 13 years, South America’s Paraguay converted an incredible 78 percent of its remaining forest wilderness mainly into large-scale soybean farms and rough pasture, the study found. Satellite images and maps on the new Global Forest Watch website offer see-it-with-your-own eyes images of Paraguay’s forests vanishing over time.
The images and data collected for the study are accessible via various tools on the website. They reveal that 25 percent of Europe’s largest remaining forest, located 900 km north of Moscow, has been chopped down to feed industrial logging operations. In the Congo, home of the world’s second largest tropical forest, 17 percent has been lost to logging, mining and road building. The Global Forest Watch website also shows details of huge areas of Congo forest licensed for future logging.
Deforestation starts with road building, often linked to logging and extractive industries, said Thies. In some countries, like Brazil and Paraguay, the prime reason is conversion to large-scale agriculture, usually for crops that will be exported.
The new data could help companies with sustainability commitments in determining which areas to avoid when sourcing commodities like timber, palm oil, beef and soy. Market-led efforts need to gain further support given the lax governance and enforcement in many of these forest regions, Thies said.
He called on the Forest Stewardship Council (FSC) – a voluntary certification programme that sets standards for forest management – to “also play a stronger role” and to improve those standards in order to better protect wilderness forests.
Without urgent action to curb deforestation, it is doubtful that any large-scale wild forest will remain by the end of this century, concluded Sizer.
