Protecting half of the planet could directly affect over one billion people

Abstract

In light of continuing biodiversity loss globally, one ambitious proposal has gained considerable traction amongst conservationists: the goal to protect half the Earth. Our analysis suggests that at least 1 billion people live in places that would be protected if the Half Earth proposal were implemented within all ecoregions. Considering the social and economic impacts of such proposals is central to addressing social and environmental justice concerns, and assessing their acceptability and feasibility.
