A recent article in Current Biology (Conde et al., 2015) examined the costs of preventing the extinction of about 900 vertebrate species (and their habitats) listed by the Alliance for Zero Extinction (AZE). They calculated the costs for conservation in the animal’s natural habitats as well as for maintaining insurance populations in zoos. The total was about $1.1 billion, with an average cost per species of $1.3 million. Another report (McCarthy et al., 2012) concluded that about $1 billion per year for a decade would reduce the extinction risk for all globally threatened bird species, and $4 billion per year for a decade would downlist all threatened species on the International Union for Conservation of Nature’s Red List. A total of $76 billion per year for a decade would establish and protect habitats and ecosystems globally.
