The United States purchases the most fast-fashion products in the world, and are blind to the environmental and human-rights repercussions because manufacturing and sourcing are done in low-income countries — they don't want us to see the truth.
Many clothing manufacturers do not care about their workers — they are grossly underpaid, exposed to proven health-harming chemicals, microfibers, and have no support in basic human rights.
Often the water and natural environments of low-income countries are sacrificed, so we aren't experiencing the climb in pollution and natural destruction in our own cities.
FAST FASHION ACCOUNTS FOR ~10% OF GLOBAL CARBON EMISSIONS
Textile production is a major contributor to climate change. It produces an estimated 1.2 billion tons of CO2 equivalent (CO2e) per year — more than international flights and maritime shipping combined. https://publications.parliament.uk/pa/cm201719/cmselect/cmenvaud/1952/full-report.html
Extending the life of clothing by an extra nine months could reduce carbon, waste and water footprints by around 20–30% each. https://publications.parliament.uk/pa/cm201719/cmselect/cmenvaud/1952/full-report.html
