In light of continuing global biodiversity loss, one ambitious proposal has gained considerable traction amongst conservationists: the goal to protect half the Earth. Our analysis suggests that at least one billion people live in places that would be protected if the Half Earth proposal were implemented within all ecoregions. Taking into account the social and economic impacts of such proposals is central to addressing social and environmental justice concerns, and assessing their acceptability and feasibility. Recently, ecologists have begun discussing an idea for setting aside half of the Earth for conservation purposes. This study provides some of the first analysis of the impacts of doing so on society, based on assumptions about ecoregions and human footprint.
