Conserving Just 1.2% of Earth's Land Could Save Most Threatened Species From Extinction
More than a third of the sites identified as most vulnerable lie within a mile and a half of lands that are already protected, making the task entirely "doable," said one scientist.
Researchers revealed in a study published Monday that world governments are not doing enough to save the most endangered plant and animal species from extinction, and called for a more targeted approach to protect biodiversity.
Eric Dinerstein, a senior biodiversity expert at Resolve, led a team of researchers in the analysis, which was published in Frontiers in Scienceand revealed that conserving just 1.2% of the Earth's surface would avert the extinction of the most threatened species on the planet.
The scientists set out to identify the rarest species in the world in limited habitats, with Dinerstein noting that the majority of species are rare.
Most species "either have very narrow ranges or they occur at very low densities or both," he told The Guardian, suggesting that setting aside large percentages of the Earth's land isn't needed to protect the most threatened animals.
For example, the World Wildlife Fund identifies the Javan rhino as the most endangered species on Earth, having suffered "a staggering decline in their numbers due to hunting and habitat loss." Javan rhinos are found only on the island of Java, Indonesia.
Similarly, the Amur leopard has been critically endangered since 1996 and is only found in "a relatively small region of the far east of Russia and northeastern China at present."
"It's almost as if countries are using a reverse-selection algorithm and picking the non-rare sites to add to the global areas under protection. The call to arms of this paper is that we have to be doing a much better job in the next five years."
The study identified 16,825 sites around the world that should be prioritized for conservation over the next five years in order to prevent the extinction of animals and plants that are found only in those places.
Dinerstein told The Guardian that protecting the most vulnerable places is entirely "doable," especially considering 38% of the identified sites are within one and a half miles of areas that are already protected.
More than half the sites are in the Philippines, Brazil, Indonesia, Madagascar, and Colombia.
"Only 7% of the new protected areas between 2018 and 2023 overlapped with the conservation imperative sites," Dinerstein warned, calling for a more targeted approach. "It's almost as if countries are using a reverse-selection algorithm and picking the non-rare sites to add to the global areas under protection. The call to arms of this paper is that we have to be doing a much better job in the next five years."
The United Nations Environment Program reported in 2021 that 16.6% of the world's land surface and waters are currently protected.
Through land purchases, the creation of protected areas on federal lands, the leasing of community reserves and forests, and the expansion of Indigenous rights and land sovereignty, the study says, all of the key sites identified by researchers could be protected over the next five years for roughly $29 billion to $46 billion.
No one is coming to save us. Join with us.
| The world is a pretty dark place right now. Economic inequality off the charts. The climate emergency. Supreme Court corruption in the U.S. and corporate capture worldwide. Democracy in many nations coming apart at the seams. Fascism threatens. It’s enough to make you wish for some powerful being to come along and save us. But the truth is this: no heroes are coming to save us. The only path to real and progressive change is when well-informed, well-intentioned people—fed up with being kicked around by the rich, the powerful, and the wicked—get organized and fight for the better world we all deserve. That’s why we created Common Dreams. We cover the issues that corporate media never will and lift up voices others would rather keep silent. But this people-powered media model can only survive with the support of readers like you. Can you join with us and donate right now to Common Dreams’ Mid-Year Campaign? |
