“The planet is in peril, and it’s clear that we cannot restore it without transforming our food system,” says the World Wildlife Fund in an introduction to its 10 tips for eating sustainably. “What we eat has changed the planet. Across the globe forests have been devastated to make space to rear cattle and to grow crops to feed livestock, while our oceans become barren as they are trawled and overfished.” The tips include: eating plants, eating a greater variety of plants, and eating foods that are in season; growing our own food; cutting food waste; avoiding plastic; and getting Giki, a new app that provides ethical and sustainability information on more than 250,000 products in UK supermarkets.
