10,000 liters of water is required to grow one kilo of cotton needed to make just one pair of denim jeans. In comparison, one person would take 10 years to drink 10,000 liters of water.
Cumulatively, the fashion industry produces about 20% of global waste water.
World Wildlife Fund reports, “Cotton’s most prominent environmental impacts result from the use of agrochemicals (especially pesticides), the consumption of water, and the conversion of habitat to agricultural use. Diversion of water and its pollution by cotton growing has had severe impacts on major ecosystems such as the Aral Sea in Central Asia, the Indus Delta in Pakistan and the Murray Darling River in Australia.”
