Far-reaching global assessment details how humanity is undermining the very foundations of the natural world
On the heels of an Earth Day that featured calls for radical action to address the current “age of environmental breakdown,” Agence France-Presse revealed Tuesday that up to a million species face possible extinction because of destructive human behavior.
The warning comes from a forthcoming United Nations report, a draft of which was obtained by AFP, that “painstakingly catalogues how humanity has undermined the natural resources upon which its very survival depends.”
A product of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the landmark three-year assessment was prepared by 150 experts from 50 countries, with additions from another 250 contributors.
As John Vidal wrote in a preview of the study for HuffPost last month, “It is the greatest attempt yet to assess the state of life on Earth and will show how tens of thousands of species are at high risk of extinction, how countries are using nature at a rate that far exceeds its ability to renew itself, and how nature’s ability to contribute food and fresh water to a growing human population is being compromised in every region on Earth.”
Outlining some of the experts’ key findings, AFP reported Tuesday:
The accelerating loss of clean air, drinkable water, CO2-absorbing forests, pollinating insects, protein-rich fish, and storm-blocking mangroves—to name but a few of the dwindling services rendered by nature—poses no less of a threat than climate change…
The direct causes of species loss, in order of importance, are shrinking habitat and land-use change, hunting for food or illicit trade in body parts, climate change, pollution, and alien species such as rats, mosquitoes, and snakes that hitch rides on ships or planes, the report finds.
Although IPBES chair Robert Watson declined to divulge the new report’s details to AFP, he said that “there are also two big indirect drivers of biodiversity loss and climate change—the number of people in the world and their growing ability to consume.”
“We need to recognize that climate change and loss of nature are equally important, not just for the environment, but as development and economic issues as well,” Watson added. “The way we produce our food and energy is undermining the regulating services that we get from nature.”
As AFP reported, the draft document warns that “subsidies to fisheries, industrial agriculture, livestock raising, forestry, mining and the production of biofuel, or fossil fuel energy encourage waste, inefficiency, and over-consumption.”
Unsustainable human activity, according to the document, already has “severely altered” 40 percent of the marine environment, 50 percent of inland waterways, and three-quarters of the planet’s land.
Looking ahead, the report says that “half-a-million to a million species are projected to be threatened with extinction, many within decades.” It also warns that indigenous peoples and poor communities—who are already at risk because of the global climate crisis—will be negatively impacted by biodiversity loss.
“The loss of species, ecosystems, and genetic diversity is already a global and generational threat to human well-being,” Watson said in a statement from IPBES. “Protecting the invaluable contributions of nature to people will be the defining challenge of decades to come. Policies, efforts, and actions—at every level—will only succeed, however, when based on the best knowledge and evidence. This is what the IPBES Global Assessment provides.”
Some of the language may change in the report—which echoes previous warningsabout mass extinction—during the upcoming seventh session of the IPBES Plenary, scheduled for April 29 to May 4. However, the major figures and conclusions are expected to remain the same. The final document is due out May 6.
