“Telling the Truth,” as per Extinction Rebellion’s first rule, turns out to be a bit complicated. It’s easy to tell the “We’re probably fucked” part of the story. The hard part is imagining a way forward.
Back in January, a group of 17 ecologists and environmental scientists — prominently including Paul Ehrlich — published Underestimating the Challenges of Avoiding a Ghastly Future in Frontiers in Conservation Science.
It’s a must read, and a grim one. And can’t hope to improve on the summary ecologist Carl Safina gave in Yale Environment 360 when he said that it reads “reads less as an argument than as a rain of asteroids encountered in the course of flying blind on a lethal trajectory,” or his summary of its findings, which only begin with biodiversity loss. Here (minus the links) is a sample:
“Major changes in the biosphere are directly linked to the growth of human systems. While the rapid loss of species and populations differs regionally in intensity, and most species have not been adequately assessed for extinction risk, certain global trends are obvious. Since the start of agriculture around 11,000 years ago, the biomass of terrestrial vegetation has been halved , with a corresponding loss of >20% of its original biodiversity, together denoting that >70% of the Earth’s land surface has been altered by Homo sapiens . There have been >700 documented vertebrate and ~600 plant species extinctions over the past 500 years, with many more species clearly having gone extinct unrecorded . Population sizes of vertebrate species that have been monitored across years have declined by an average of 68% over the last five decades, with certain population clusters in extreme decline , thus presaging the imminent extinction of their species . Overall, perhaps 1 million species are threatened with extinction in the near future out of an estimated 7–10 million eukaryotic species on the planet, with around 40% of plants alone considered endangered . Today, the global biomass of wild mammals is <25% of that estimated for the Late Pleistocene , while insects are also disappearing rapidly in many regions.”
But I’m not writing to ask you to read the “ghastly” paper. I’m writing to ask you to read it, and then to read Safina’s review of it, and then to read Notes from a 1.2C world, a response the emerging critic Laurie Laybourn-Langton wrote of it, and my own response, below, though with the stipulation that is an it’s an “insider” document I wrote to the folks at The Omega Network after attending the webinar they organized to discuss it. And I’m asking you, after doing all this reading, to up your game.
What’s the problem? That this paper, brilliant though it is in describing the deterioration of our planetary home, it is not equally brilliant when it comes to helping us work out how to respond. Which was to be expected back in the old days, but this is 2021 — the eye of the storm — and the second wind is approaching, and what matters now is what we’re going to do.
Not that Ghastly’s description of the problem is bad . . .
