evidence: Globally, the fashion industry is estimated to contribute 3 - 10% of the greenhouse gas emissions that are causing climate change, based on scientific studies and reports from the United Nations and charities. The clothing industry has a variety of other environmental impacts, including intensive water use, water pollution through dying and textile production, and pesticide and herbicide pollution through the agricultural production of cotton. Microplastics, which are shed primarily from synthetic textiles during washing, are also polluting the oceans, potentially negatively impacting human health and natural ecosystems.
