Greenpeace released the results of a months-long global investigation into some of the world?s top-selling fast fashion houses, with sample products purchased from nearly 30 countries. According to Greenpeace, nearly two thirds of the clothing tested positive for hormone-disrupting and dyes that release cancer-causing substances.
