Half-Earth: Our Planet’s Fight for Life

"Half-Earth" proposes an achievable plan to save our imperiled biosphere: devote half the surface of the Earth to nature.

In order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet, says Edward O. Wilson in his most impassioned book to date. "Half-Earth" argues that the situation facing us is too large to be solved piecemeal and proposes a solution commensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature.

Half-Earth Project

Bringing Half-Earth to Life
If we conserve half the land and sea, 85% of species will be protected from extinction. The Half-Earth Project’s programs convene expert partners and leaders in an inspiring campaign to raise conservation efforts to a new level and enhance our resilience. The Half-Earth Project will 1) drive the research needed to better understand and care for our world, 2) provide leadership to guide conservation efforts, and 3) engage people to participate broadly in the transcendent goal to conserve Half-Earth.
