Rewild half the planet by 2050.

The E.O. Wilson Half-Earth thesis makes a simple but profound argument: to preserve the biodiversity that sustains all life on this planet, we need to protect and restore at least half of the Earth's surface.

This isn't idealism — it's the minimum viable target supported by conservation science. We are currently losing species at 1,000 times the natural background rate. Ecosystems that took millions of years to evolve are being dismantled in decades.

But rewilding at scale is also the most effective nature-based climate solution available to us. Restored ecosystems sequester carbon, regulate water cycles, prevent flooding, purify air, and support the pollination systems that underpin global food production.

The economic value of nature's services has been estimated at $125 trillion per year — more than global GDP. Yet we treat these services as free. The mission is to change that: to make nature's value visible, measurable, and investable, so that restoring the planet becomes not just the right thing to do, but the profitable thing to do.
