The fashion industry is built on two dominant fabrics — cotton and polyester.
Polyester is plastic. It sheds microplastics, releases toxic chemicals, and never truly decomposes. It is a disaster.
But cotton? That is the “sustainable” choice, right? Not quite. Cotton is one of the most water-intensive, pesticide-heavy crops on the planet.
There is a better alternative. Hemp.
Hemp is not just another fabric. It is the future of truly sustainable fashion.
Let’s break down how hemp stacks up against cotton, and why the industry does not want you to know about it.
Water Usage: Hemp Wins
💧 Cotton is one of the thirstiest crops in the world.
It takes 2,700 litres of water to produce a single cotton T-shirt.
Cotton farming drains rivers and destroys ecosystems.
Over 20,000 litres of water are needed to produce just one kilogram of cotton.
🌱 Hemp uses 50% less water than cotton.
It thrives on rainwater rather than irrigation.
It regenerates the soil instead of depleting it.
It can be grown in areas where cotton simply would not survive.
If every cotton farm switched to hemp, millions of litres of water would be saved every single year.
Pesticides and Chemicals: Hemp Wins
🚜 Cotton is known as the “dirty crop” for a reason.
It accounts for 16% of global pesticide use.
Pesticides from cotton farming leach into water supplies and poison communities.
Many pesticides used on cotton are classified as hazardous to human health.
🌱 Hemp needs no pesticides or herbicides.
It is naturally resistant to pests.
It enriches the soil instead of degrading it.
It grows faster and stronger without chemical intervention.
Cotton requires constant chemical treatment just to survive. Hemp thrives on its own.
Durability and Longevity: Hemp Wins
👕 Cotton wears out fast.
Cotton fibres break down quickly, leading to fast fashion waste.
It weakens with every wash, needing frequent replacements.
Over 85% of cotton clothing ends up in landfills.
🛡 Hemp is 3x stronger than cotton.
It lasts longer, meaning fewer replacements.
It gets softer over time while staying strong.
Hemp clothing is naturally antibacterial, resisting odours and bacteria growth.
Fast fashion relies on cheap, short-lived materials to keep consumers buying more.
Hemp disrupts that cycle with clothes that last.
Environmental Impact: Hemp Wins
🌍 Cotton farming is unsustainable.
It strips the land of nutrients, requiring constant fertiliser.
It is a major contributor to deforestation in developing countries.
Cotton fields take up 2.5% of the world’s farmland but cause 24% of insecticide pollution.
🌱 Hemp regenerates the earth.
It absorbs more CO2 per acre than trees.
It restores soil health rather than draining it.
It can be grown on small-scale farms without harming biodiversity.
Hemp is not just sustainable. It is regenerative.
Why is Cotton Still the Industry Standard?
If hemp is this much better, why is cotton still the dominant crop?
💰 The cotton industry is deeply embedded in global trade.
🚫 Hemp farming was restricted for decades due to outdated laws.
🛍 Fast fashion brands rely on cheap, disposable materials.
Switching to hemp would mean brands could no longer produce low-quality, high-margin clothing at scale. They need cotton to keep production costs low and sales high.
But that is changing. Consumers are waking up.
The Future is Hemp
Fashion does not need cotton fields soaking up the planet’s resources.
It needs:
✅ Clothes that last instead of being thrown away
✅ Fabrics that do not poison the soil
✅ Materials that are strong, biodegradable, and ethical
Hemp is not just another fabric. It is the answer to fast fashion’s destruction.
