Animal agriculture, encompassing meat, eggs, dairy, and co-products, is a major contributor to climate change, next only to fossil fuels. Despite scientific warnings, world leaders continue to support the industry, harming animals, the planet, and farmers alike. A shift to plant-based diets would significantly reduce land use, deforestation, and greenhouse gas emissions, while also offering economic benefits to farmers. With one of the world’s most innovative vegan markets, the UK is well-positioned to lead the transition away from animal farming and mitigate the climate crisis.
