This BBC article https://www.bbc.com/news/world-48908413 is thought-provoking. It fits right in with the clothes pollution thread earlier.
I rather agree with the information provided. I air my blouses/tops and wear more than once, briefs and socks do get washed after each use, use liquid detergent and cold water. Some other ideas that are new to me though.
A few quotes:
Killing the planet one microfibre at a time
This isn't the first time McCartney has recommended not washing our clothes. In fact, she has long advocated avoiding the washing machine - both for the longevity of the garments, but also because of the impact washing them has on the environment.
Laura Diáz Sánchez, from the Plastic Soup Foundation advocacy group, agrees with this, particularly when it comes to high-street clothes, which contain more synthetic materials such as polyester and acrylic.
"Every time we wash our clothes an average of nine million [plastic] microfibres are released into the environment," she tells BBC News. "The way we wash our clothes affects this, as well as the way our clothes are made - but the more we wash our clothes, the more microfibres are released."...
Leave your jeans alone
Sarah Clayton, head of the Love Your Clothes campaign by environmental charity Wrap, also suggests not washing your jeans, but airing them between wears instead: "If they have a stain you could try spot-cleaning them with water rather than washing the whole garment."
Letting your jeans fester unwashed may sound a bit unsavoury, but one man in the know swears by it - Chip Bergh, the CEO of Levi's.
