Protected natural areas have historically been the primary tool of conservationists to conserve land and wildlife. These parks and reserves are set apart to forever remain in contrast to those places where human activities, technologies, and developments prevail. But even as the biodiversity crisis accelerates, a growing number of voices are suggesting that protected areas are passe. Conservation, they argue, should instead focus on lands managed for human use-working landscapes-and abandon the goal of preventing human-caused extinctions in favor of maintaining ecosystem services to support people. If such arguments take hold, we risk losing support for the unique qualities and values of wild, undeveloped nature.
