High street fashion brands, including Zara, Metersbonwe and Calvin Klein, are selling clothing contaminated with hazardous chemicals that break down to form hormone disrupting or even cancer-causing chemicals when released into the environment, according to a report by Greenpeace International. Greenpeace organises a ‘fashion show’ on a makeshift runway, during the launch of the report, “Toxic Threads: The Big Fashion Stitch-Up.” Investigations found hazardous chemicals in clothing from 20 leading fashion brands, that contribute toward toxic water pollution both when they are made, and when they are washed.
