The world's biomass is shrinking...

.

Most other animals are fish. Mammals account for only about 8 percent of animal biomass and only about 0.03% of all biomass. However, within the realm of mammals, humans dominate. Human livestock, at 0.1 Gt C, account for 59.9% of all mammal biomass on Earth; humans themselves, at 0.06 Gt C, account for 35.9 %. All wild mammals, marine and terrestrial, account for only 4.2% of mammal biomass.

In the oceans, human fishing has depleted 85% of commercial fish stocks and 90% of “big fish” – tuna, marlin, and sharks. The global marine catch is down by 6.4% since the 1992, in spite of larger ships, larger nets, and improved technology. Oxygen-depleted ocean zones have increased by 75%. This is on top of acidification from carbon emissions which kills coral reefs that act as marine breeding grounds. The exploitation of marine mammals, including whales, has reduced marine mammals by 80%.

Here is an article on insect biomass collapsing... the latest... Insect go man may go too...

The insect apocalypse: ‘Our world will grind to a halt without them’

Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they perform

In October 2019 a different group of German scientists published their findings from a study of insect populations in German forests and grasslands over 10 years from 2008 to 2017. The study’s results were deeply troubling. Grasslands fared worst, losing on average two-thirds of their arthropod biomass (the insects, spiders, woodlice and more). In woodlands, biomass dropped by 40%.

Here is an earlier article...


Plummeting insect numbers 'threaten collapse of nature'

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

Here is this even earlier...


A giant insect ecosystem is collapsing due to humans. It's a catastrophe

Insects have triumphed for hundreds of millions of years in every habitat but the ocean. Their success is unparalleled, which makes their disappearance all the more alarming

So what is the future for 21st-century insects? It will be worse still, as we struggle to feed the nine billion people expected to be inhabiting the world by 2050, and the possible 12 billion by 2100, and agriculture intensifies even further to let us do so. You think there will be fewer insecticides sprayed on farmlands around the globe in the years to come? Think again. It is the most uncomfortable of truths, but one which stares us in the face: that even the most successful organisms that have ever existed on earth are now being overwhelmed by the titanic scale of the human enterprise, as indeed, is the whole natural world.

Here is another on biomass around the world and we are in a new age... think chicken bones... the have some ggod visionals...


The transformation of the planet by human activity has led scientists to the brink of declaring a new geological era – the Anthropocene. One suggested marker for this change are the bones of the domestic chicken, now ubiquitous across the globe.

The new work reveals that farmed poultry today makes up 70% of all birds on the planet, with just 30% being wild. The picture is even more stark for mammals – 60% of all mammals on Earth are livestock, mostly cattle and pigs, 36% are human and just 4% are wild anima
ls.

Since the rise of human civilisation 83% of wild mammals have been lost
Plants account for 82% of all biomass on the planet – 7,500 times more than humans

Here is another fishy story the deepest fish ever...

//www.smithsonianmag.com/smart-news/behold-the-deepest-fish-ever-filmed-180981937/#:~:text=April%205%2C%202023%203%3A07%20p.m.&text=Scientists%20have%20taken%20video%20footage,fish%20ever%20captured%20on%20film.

April 5, 2023 3:07 p.m. Scientists have taken video footage of a fish more than five miles below sea level. Swimming 8,336 meters beneath the surface, the animal is now the deepest fish ever captured on film

They going to pick a date for start of the age of man... The Anthroponce... We all were here to see it's dawn... Nuclear fallout starts the age off...
