The T-shirt you are currently wearing, regardless of which one it is, required approximately 2,700 litres of fresh water to be produced.
This number comes from the World Wildlife Fund, which considers the water used for growing the cotton, the water needed for dyeing and chemically treating the fibers, the water lost during fabric processing at the mill, and the water utilized at every subsequent stage until the finished product reaches retail. If an individual drank two litres of water each day for two and a half years—as recommended by the World Health Organization—they would consume the same amount of water the T-shirt needed before it was ever worn.
It’s a challenging figure to grasp. It’s one of those statistics that become abstract as soon as it enters the mind. Two thousand seven hundred litres. A T-shirt. Two and a half years of someone’s drinking water. The units seem mismatched, leading the mind to seek more comfortable thoughts.
This disconnection is partly why the fashion industry has maintained such extensive operations for this long.
## The source of the water
The T-shirt in question was likely not made anywhere near your location.
The cotton used in a typical Western consumer’s apparel is cultivated in specific parts of the world that have become the industry’s preferred production areas over recent decades. The three top cotton-producing nations are China, India, and the United States, followed by Pakistan, Brazil, Uzbekistan, and various smaller producers. The fabric processing that transforms raw cotton into finished cloth is most concentrated in Bangladesh, Vietnam, Cambodia, Indonesia, and again in China and India.
These locations are not chosen by chance. They are selected for particular reasons — low labor costs, lax environmental regulations, established infrastructure, and, importantly, water. Cotton is among the most water-intensive crops globally, and cotton processing is one of the most water-demanding industrial practices in contemporary manufacturing. Therefore, the geography for cotton production must also be a geography with abundant water.
The issue arises because the specific water-abundant regions that once supported viable cotton production are, in many instances, no longer rich in water. Some have been exhausted by the industry itself.
The Aral Sea in Central Asia—once the fourth largest lake globally—has essentially vanished in the last sixty years, primarily due to the diversion of its feeding rivers for cotton irrigation in Uzbekistan and Kazakhstan. What was once a body of water the size of Ireland is now a salt desert with a few remaining pools of water in what used to be its center. The Aral’s disappearance stands as one of the most significant acts of ecological devastation associated with a single industry.
In Bangladesh, which is one of the largest garment manufacturing centers worldwide, textile factories consume around 1.5 trillion litres of water each year. This groundwater is being withdrawn at a rate far exceeding replenishment. Aquifers are declining. Wells are depleting. Residents of the same towns as the mills face water shortages significantly influenced by the production of clothing intended for consumers across the globe.
## Visualizing 79 billion cubic meters
The industry-wide figure—approximately 79 billion cubic metres of fresh water used annually—should be converted into a more tangible form.
Seventy-nine billion cubic meters is enough to fill Loch Ness, Scotland’s largest lake by volume, about ten times. It is sufficient to meet the entire annual freshwater needs of the United Kingdom twice over, with a significant surplus remaining. By any reasonable assessment, it’s enough water to provide each of the 2.2 billion people currently lacking reliable access to safe drinking water with the World Health Organization’s daily minimum requirements for several decades.
That last comparison resonates deeply. The industry is using annually a volume of water adequate to fully address the world’s most significant ongoing humanitarian water crisis for decades. Furthermore, it is doing so primarily in the same countries where this humanitarian crisis is most severe.
The 2.2 billion individuals currently without safe drinking water are not scattered randomly across the globe. They are primarily located in regions that significantly overlap with the fashion industry’s production areas. The same countries whose populations struggle to access clean water are where cotton is being farmed, where fabric is being dyed, and from where finished garments are shipped to consumers who will typically wear them only a few dozen times before discarding them.
## The significance of the T-shirt
The T-shirt represents just one article of clothing. The assertion is not that any one purchase constitutes a moral failing. Rather, the assertion is that the total operation of the industry is extracting vast amounts of fresh water from regions that cannot afford to lose it, doing so at a scale that is hard to fully comprehend until the specific geography is considered.
