You know what needs to be done: save nature and end the biodiversity crisis. What you might not know is how we’re going to do it. The best contemporary science and traditional wisdom tell us that nature needs half. That may seem like a lot, but we have a plan for how to get there and transform the way society thinks about nature.

Protect 50% of the planet by 2050

WHAT WE DO

Nature Needs Half is an international coalition of scientists, conservationists, nonprofits, and public officials defending nature at the scale she needs to continue to function for the benefit of all life. And we’ve got a global ground game in place that will protect 50% of the planet by 2050, turning the tide in favor of Earth’s life support systems and transforming society’s relationship with nature, one ecoregion and country at a time.

The Science

Why Act Now

We can stop the sixth mass extinction if we protect approximately 50% of the 846 ecoregions that provide habitat for all of Earth’s biodiversity. That means finding leaders and organizations around the world willing to align existing efforts around protecting and interconnecting nature in their region.
