“Americans chucked more than 21 billion pounds of clothing and other textiles into landfills in 2015 ... Water pollution and greenhouse gas emissions—fueled in part by the rise of the cheap, disposable clothing called “fast fashion.” ... A 2018 review published in the Journal of Cleaner Production ... concluded that lengthening a garment’s life by reusing it reduced its environmental impact. Research by Waste and Resources Action Program (WRAP) ‘shows extending the average life of clothes by just three months of active use per item would lead to a 5 to 10 percent reduction in each [item’s] carbon, water and waste footprints.’”
