Nature Needs Half™
Protecting and interconnecting at least half of the planet’s land and water is necessary to sustain the health, function, and diversity of all life.

Nature Needs Half™ is a science-based and common-sense vision of a relationship between people and nature that ensures enough natural areas of land and water are protected and interconnected – and of sufficient size and resiliency – to provide life-supporting ecosystem and biodiversity services that are essential to both human health and prosperity and a bountiful, beautiful legacy of wild nature. NNH in practice recognizes that human well-being and security depend greatly on a healthy and abundant natural world, and also that Nature itself has a right to exist freely. The NNH principle is central to achieving a truly sustainable society – one that integrates traditional and Indigenous knowledge and life-ways with conservation science and management, and meets human needs while leaving “at least half” in wild nature. For people and nature to survive, we must share Earth, at least equally.
