In this commentary, Susan Lieberman, David Wilkie, and James Watson from the Wildlife Conservation Society (WCS) contend that the protection of Indigenous Peoples’ rights is crucial to the survival of humanity. The destruction of the Earth’s ecological systems has set the planet on a path toward its sixth mass extinction event: climate change catastrophe. The authors argue that if 30 percent of the world’s intact land and water is equitably protected by 2030, this crisis could potentially be diverted; however, evidence shows that this is only possible if leaders recognize the value and critical importance of Indigenous ecological knowledges and land stewardship to the survival of animals, plants, lands, waters— and, ultimately, humanity. Indigenous rights and traditional stewardship must be respected, honored, and protected by people, corporations, and governments across the globe. Photo credit: David Wilkie/WCS
