There are very few people today who don’t wear jeans. Thanks to globalization, denim has long become a global style statement. Alongside its popularity, demand, production, and prices have soared. Yet, most denim users are unknowingly contributing to the silent destruction of nature. Jeans have become a hidden cause behind the ecological crisis.
Yes, that’s what researchers are warning. A recent international exhibition in Paris showcased this alarming reality. The exhibition, dedicated to jeans, revealed that more than 70 denim products are sold every second worldwide. That adds up to over 2.2 billion jeans sold annually. The exhibition highlighted how this massive production is causing irreversible environmental damage every single moment.
Even before this exhibition, researchers had already raised concerns about the environmental impact of jeans. Several studies pointed out that producing a single pair of jeans requires 2,600 to 5,200 gallons of water — nearly 10,000 to 20,000 liters! Most of this fresh water is drawn from rivers, lakes, or underground sources, as freshwater is essential for processing denim. This overuse of water is directly contributing to worsening water crises.
One of the most alarming examples is the Aral Sea. Located in present-day Uzbekistan (formerly part of the Soviet Union), the area around the Aral Sea saw a boom in denim factories during the 1950s. Cotton (used to make denim) was grown extensively in the region. While this was profitable commercially, it ultimately led to the death of the Aral Sea. Cotton cultivation demands vast amounts of water, which quickly depletes underground reserves. That’s exactly what happened to the Aral Sea. Simultaneously, water from the sea was extracted in huge quantities for denim manufacturing.
But the damage didn’t stop there. The water used in the denim production process — often mixed with dyes, chemicals, and pesticides — was drained back into the Aral Sea. Over time, this polluted the sea, killing off nearly 24 species of fish and leaving thousands of fishermen unemployed. According to satellite data, 90% of the Aral Sea’s water has dried up between 1950 and 2020. Toxic chemical sediments left behind are now carried by wind and sand to nearby regions, causing serious health issues like cancer. A similar crisis is unfolding along the Mato Grosso River in Brazil, where cotton farming is rapidly drying out vast areas of savannah land.
There’s more. Denim manufacturing emits large amounts of greenhouse gases and consumes enormous energy resources. Even when users wash their jeans, microfibers and chemicals are released into the environment, further polluting it.
Years ago, after multiple studies exposed the harmful impact of jeans, several global denim brands pledged to manufacture “green jeans” — environmentally friendly alternatives. However, these eco-friendly jeans cost several times more than regular jeans, resulting in lower demand and production. Even a decade later, the situation hasn’t improved — in fact, denim-related pollution has only intensified.
But is there a solution?
It may not be feasible to eliminate jeans from human civilization overnight. However, researchers suggest washing jeans less frequently can significantly reduce pollution. Avoiding unnecessary purchases and extending the lifespan of each pair of jeans can also reduce both demand and production — ultimately helping the environment. According to experts, this is the first step humanity must take toward controlling denim-driven pollution.
