Wild Vertebrates vs. Modern Westernized humans: Can one live without the other? I doubt it

 AT CURRENT RATES OF DECLINE, VIRTUALLY 100% of WILD VERTEBRATES WILL DIE OFF BY YEAR ZERO : 2026.

That's also one one arctic sea ice researcher predicts an Ice-Free arctic for the first time in 3 million years! This will add 1 trillion to GHG equivalent in temperature warming!! That means a one third increase in temperature. That will cause the ESAS Methane Bomb to accelerate - doubling global warming again!!

That will cause ALL life on Earth to die off.

The team collated such estimates for 16,700 populations of mammals, birds, reptiles, amphibians, and fish, across 4,000 species. (Populations here refers to pockets of individuals from a given species that live in distinct geographical areas.)That covers just 6.4 percent of the 63,000 or so species of vertebrates—that is, back-boned animals—that are thought to exist.

 Ultimately, they found that from 1970 to 2014, the size of vertebrate populations has declined by 60 percent on average. That is absolutely not the same as saying that humans have culled 60 percent of animals—a distinction that the report’s technical supplement explicitly states. “It is not a census of all wildlife but reports how wildlife populations have changed in size,” the authors write.

 To understand the distinction, imagine you have three populations: 5,000 lions, 500 tigers, and 50 bears. Four decades later, you have just 4,500 lions, 100 tigers, and five bears (oh my). Those three populations have declined by 10 percent, 80 percent, and 90 percent, respectively—which means an average decline of 60 percent. But the total number of actual animals has gone down from 5,550 to 4,605, which is a decline of just 17 percent.

 The uncertainties mount when you consider that the 63,000 species of vertebrates are vastly outnumbered by the untold millions of species of invertebrates—spineless creatures like insects, worms, jellyfish, and sponges, which make up the majority of animal life. Their fates are murkier because scientists have collectively spent less time monitoring them

  At least a third of amphibians face extinction, thanks to climate change, habitat loss, and an apocalyptic killer fungus. Even invertebrates aren’t off the hook. There might be fewer data for them, but the data that exist paint an alarming picture of rapidly disappearing insects, even in supposedly pristine forests. Meanwhile, in the oceans, coral reefs are bleaching too quickly to recover: Half of the corals in the Great Barrier Reef have died since 2016. All this evidence points to a period of “biological annihilation” that some have likened to the five great mass extinctions of the past.
