Clothing's Pollution Problem: What's The Environmental Cost?

The fashion industry is a major contributor to pollution. It is the second-largest consumer of water and the second-largest polluter of water, with textile dyeing being the world's second-largest polluter of water. The industry's methods and materials are highly polluting, and its use of fossil fuels generates carbon dioxide, contributing to global warming. The fast fashion business model promotes the rapid production of cheap, disposable clothing, leading to enormous quantities of clothing ending up in landfills. The environmental damage caused by the industry is increasing as it grows, and it is essential to address the problem and encourage sustainable practices.

The fashion industry is the second-largest polluter of water

The fashion industry is a major contributor to water pollution and consumption. It is the second-largest consumer of water, requiring about 700 gallons to produce one cotton shirt and 2,000 gallons of water to produce a pair of jeans. The industry is responsible for 20% of global wastewater, with 93 billion cubic meters of water used annually, enough for 5 million people to survive.

Textile dyeing is the world's second-largest polluter of water, as the water leftover from the process is often dumped into ditches, streams, or rivers. The dyeing process uses enough water to fill 2 million Olympic-sized swimming pools each year. The fashion industry is responsible for 8% of global greenhouse gas emissions and 10% of carbon emissions, more than all international flights and maritime shipping combined.

The production of synthetic fibers, such as polyester, acrylic, and nylon, which are used in the majority of garments, is much more energy-intensive than natural fibers. These synthetic fibers take hundreds of years to biodegrade and contribute significantly to ocean pollution. Washing clothes releases 500,000 tons of microfibers into the ocean each year, with many of these fibers being polyester.

The environmental impact of the fashion industry is further exacerbated by the constant need for new designs and collections, leading to the frequent discarding of old clothes. This "fast fashion" model has resulted in a 60% increase in the number of garments purchased in 2014 compared to 2000, with clothing production doubling during this period. The industry's negative effects are also felt in developing nations, where the majority of garments are produced due to cheap labor and lenient laws and regulations. These countries often face land degradation and water pollution as a result of the fashion industry's practices.

Textile dyeing is the world's second-largest water polluter

The fashion industry is the world's second-largest polluter of water, with textile dyeing being a significant contributor. The dyeing process uses enough water to fill 2 million Olympic-sized swimming pools each year, and the resulting wastewater is often dumped untreated into rivers and streams, causing severe environmental and health issues.

Textile dyeing is a major water polluter due to the release of untreated toxic wastewater into natural water bodies. This wastewater contains harmful chemicals and dyes, which have toxic effects on aquatic life and the health of people living nearby. The social and economic development in China, for instance, has led to a significant deterioration in its water environment, impacting sustainable regional development.

The fashion industry's massive consumption of water for dyeing and finishing processes also contributes to water scarcity. Cotton, a widely used fabric, requires a lot of water to grow and produce, putting pressure on freshwater resources. The dyeing process alone uses an estimated 5 trillion liters of water annually, according to the WRI.

To address these issues, initiatives have been launched to promote more sustainable practices in the fashion industry. The UN's Alliance for Sustainable Fashion aims to coordinate efforts to make the industry less harmful. Researchers are also developing innovative solutions, such as a nanomaterial inspired by shellfish that can remove dyes and other pollutants from industrial wastewater.

Additionally, consumers can play a role in reducing the environmental impact of clothing by choosing second-hand or organic clothing, supporting companies with sustainable practices, and advocating for better environmental regulations in the fashion industry.

Washing clothes releases microfibres into the ocean

The fashion industry is the second-largest consumer of water and the second-largest polluter of water. It is responsible for 20% of all industrial water pollution worldwide. The environmental damage is increasing as the industry grows.

Textile dyeing is the world's second-largest polluter of water, as the water left over from the dyeing process is often dumped into ditches, streams, or rivers. The dyeing process uses enough water to fill 2 million Olympic-sized swimming pools each year. Cotton needs a lot of water to grow and is usually cultivated in warm and dry areas. Around 9,700 liters are needed to produce just 1kg of cotton. This has led to the desertification of the Aral Sea, where cotton production has entirely drained the water.

Another major source of water contamination is the use of fertilizers for cotton production, which heavily pollutes runoff waters and evaporation waters.

The heavy use of chemicals in cotton farming is causing massive freshwater and ocean water pollution. Some of these substances are also harmful to the consumer.

Washing clothes releases 500,000 tons of microfibers into the ocean each year—the equivalent of 50 billion plastic bottles. Many of those fibers are polyester, a plastic found in an estimated 60% of garments. Producing polyester releases two to three times more carbon emissions than cotton, and polyester does not break down in the ocean. A 2017 report from the International Union for Conservation of Nature (IUCN) estimated that 35% of all microplastics in the ocean—very small pieces of plastic that never biodegrade—came from the laundering of synthetic textiles like polyester. Microplastic pollution accounts for nearly a third of all ocean plastics.

Scientific studies have assessed that synthetic clothes contribute by about 35% to the global release of primary microplastics into the world's oceans, thus becoming the main source of microplastics.

The use of chemicals in cotton farming causes water pollution

The fashion industry is the second-largest consumer of water and the second-largest polluter of water. Textile dyeing is the world's second-largest polluter of water, as the water left over from the dyeing process is often dumped into ditches, streams, or rivers. The dyeing process uses enough water to fill 2 million Olympic-sized swimming pools each year. The fashion industry is responsible for 20% of all industrial water pollution worldwide.

Cotton is a water-intensive crop compared to many other fibers used in textile production. Cotton cultivation occupies 2.5% of the world's arable land but consumes 200,000 tons of pesticides and 8 million tons of fertilizers annually. The heavy use of chemicals in cotton farming is causing diseases and premature death among cotton farmers, along with massive freshwater and ocean water pollution and soil degradation. Pesticides and fertilizers contaminate rivers, lakes, wetlands, and underground aquifers, affecting biodiversity directly through immediate toxicity or indirectly through long-term accumulation.

Cotton production has depleted and degraded the soil in many areas. It has also led to the diversion of water and its pollution, severely impacting major ecosystems such as the Aral Sea in Central Asia, the Indus Delta in Pakistan, and the Murray Darling River in Australia.

To promote sustainability, some apparel companies are joining initiatives to reduce textile pollution and grow cotton more sustainably. The UN has launched the Alliance for Sustainable Fashion, which will coordinate efforts across agencies to make the industry less harmful.

Fast fashion encourages the production of lower-quality clothing

Fast fashion has an undeniably detrimental impact on the environment, with the fashion industry being the second-largest polluter of water worldwide. The industry's rapid design, production, distribution, and marketing of clothing encourage the mass production of cheap, disposable, and lower-quality clothing.

The fast-fashion model focuses on ultralow prices and condensed production cycles, allowing new styles to reach customers at a record pace. This business model creates significant environmental challenges, as the pressure to produce clothing quickly and cheaply often results in the use of inferior materials and a lack of stress testing. The result is clothing that is not built to last, with consumers treating these low-cost garments as disposable, discarding them after only a few wears.

The fashion industry's contribution to water pollution is twofold. Firstly, the dyeing and finishing processes are the second-largest polluters of water, as the water leftover from these processes is often dumped into natural water sources, containing toxic chemicals and dyes. Secondly, the industry is the second-largest consumer of water, with cotton production requiring a significant amount of water to grow. This has led to dramatic ecological consequences, such as the desertification of the Aral Sea.

The production of synthetic fibres, such as polyester, acrylic, and nylon, which are commonly used in fast fashion, is also energy-intensive, releasing more carbon emissions than natural fibres like cotton. These synthetic fibres are made from fossil fuels, contributing to the industry's carbon emissions, which account for 10% of global carbon emissions.

The environmental impact of fast fashion is further exacerbated by the industry's encouragement of overconsumption. The constant introduction of new styles and the low prices of these items urge consumers to buy more clothing than they need and to dispose of them quickly, leading to increased waste.

Overall, the fast-fashion industry's focus on speed and low prices results in the production of lower-quality clothing, which, coupled with the industry's water pollution, carbon emissions, and encouragement of overconsumption, has severe environmental consequences.
