Morrisons, Waitrose and John Lewis have said they won't be using glitter in own-brand Christmas products this year. The tiny pieces of plastic can wash into the environment, harm wildlife, and get into the food chain. The move is part of a wider push by retailers to try to reduce festive plastics pollution. Boots said it would be cutting out single-use plastic packaging from Christmas gifts, taking 2,000 tonnes of plastic from its ranges. Asda announced in September that it would launch its first sustainable Christmas range, and Tesco uses only edible glitter. Between four and 12 million tonnes of plastic waste makes its way into oceans every year, mainly through rivers, according to estimates. That plastic then breaks down into smaller, toxic pieces, which can be ingested by creatures, harming and potentially killing them, if it fills their stomachs.
