Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction | PNAS

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in the last century. Assuming all species on the brink have similar trends, more than 237,000 populations of those species have vanished since 1900. We conclude the human-caused sixth mass extinction is likely accelerating for several reasons. First, many of the species that have been driven to the brink will likely become extinct soon. Second, the distribution of those species highly coincides with hundreds of other endangered species, surviving in regions with high human impacts, suggesting ongoing regional biodiversity collapses. Third, close ecological interactions of species on the brink tend to move other species toward annihilation when they disappear—extinction breeds extinctions. Finally, human pressures on the biosphere are growing rapidly, and a recent example is the current coronavirus disease 2019 (Covid-19) pandemic, linked to wildlife trade. Our results reemphasize the extreme urgency of taking much-expanded worldwide actions to save wild species and humanity’s crucial life-support systems from this existential threat.

INTO THE RED: Climate and the fight of our lives

This is how long we have ignored warnings of a coming crisis:

It’s been more than half a century since a presidential panel under Lyndon Johnson found that fossil fuel emissions could be warming the earth.

It’s been 40 years since the National Academies of Sciences published a massive landmark study with similar conclusions.

And it’s been three decades — the span of an entire generation — since a NASA scientist named James Hansen sat before Congress and testified that human-caused global warming was not only real but “already happening now.”
