A planet-friendly plate: redesigning diets to stay within Earth's limits

A Nature World View by Johan Rockström argues that feeding people within planetary boundaries requires bold policies to adopt a planetary health diet: a plant-rich pattern from the 2025 EAT–Lancet Commission that emphasizes fruits, vegetables, nuts, legumes and whole grains with limited red meat and modest poultry/fish. Current diets drive ~30% of global greenhouse gases and 70% of freshwater use; unhealthy diets kill ~15 million people annually, and only ~1% of people live within planetary boundaries. The diet is adaptable to many cuisines and provides all essential nutrients, but urgent policy changes are needed to curb ultra-processed foods and align nutrition with Earth's limits.
