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™ (NNH) is a science-based, practical and aspirational vision that advances a reciprocal, balanced relationship between people and nature. Its aim is to ensure that enough wild land and seascapes are protected and interconnected (scientifically estimated to be at least half of any given ecoregion) to maintain nature’s life-supporting systems and the diversity of life on Earth.
The vision also promotes human health and prosperity, and secures a bountiful, beautiful legacy of resilient, wild nature. Nature Needs Half recognizes that we are part of nature, not separate from it. The “half” suggests a planet that is respectfully shared, where the needs of all living things are considered and protected equally, for the good of all.
Until now, the conservation community has been cautious in setting such ambitious goals for protecting nature, even if grounded in science. Given the urgency of the challenges we face, the conservation community and policy makers should now fearlessly embrace a goal of protecting and connecting at least half of the planet’s lands and waters. We have a duty to speak frankly about the clear implications of the science. There is a compelling need for a new, bold and hopeful vision and a call to act upon the knowledge we hold.
Simply put, Nature Needs Half, and it is time to say so.
The Nature Needs Half movement continues to grow! The Zoological Society of London – the world’s oldest and most renowned conservation science organization, working in over 50 countries – has joined with WILD to explore and illustrate how Nature Needs Half is both necessary and possible.
