    Nature's Best Hope

The Half-Earth Project ®

Threats to the natural world are multiplying. Species are going extinct at an alarming rate.

“Unless we move quickly to protect global biodiversity, we will soon lose most of the species composing life on Earth.” —E.O. Wilson.

There’s a solution. It’s called the Half-Earth Project. If we conserve half the land and sea, we can still safeguard the bulk of our planet’s biodiversity.

But what would Half-Earth look like? How would we get there?
