The biomass distribution on Earth
The world’s 7.6 billion people represent just 0.01% of the biomass of all living things, according to the linked study*. Yet since the dawn of civilization, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds.
For instance, 60% of all mammals on Earth are livestock (mostly cattle and pigs), 36% are human and just 4% are wild animals.
The new work is the first comprehensive estimate of the weight of every class of living creature and overturns some long-held assumptions. Bacteria are indeed a major life form – 13% of everything – but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world’s biomass.
Another surprise is that the teeming life revealed in the oceans by the recent BBC television series “Blue Planet II” turns out to represent just 1% of all biomass. The vast majority of life is land-based and a large chunk – an eighth – is bacteria buried deep below the surface.

Re: The biomass distribution on Earth
Yes, interesting reading. Thanks Gord.
All too often we hear how it is impossible for Humanity to be affecting something as large as global the biosphere. This paper clearly shows how we have reshaped Earth on truly planetary scales.

Re: The biomass distribution on Earth
you mean if we all jumped in the sea at the same time it would not cause the sea level to rise,as some climate change deniers would have us believe..........

A lot of climate change believers would like to see this become a recommendation .

Re: The biomass distribution on Earth
The US is over populated, The world is overpopulated. Until people are willing to talk about the problem it will only get worse.
I'm a vet. I did my part to help the problem.

Re: The biomass distribution on Earth
Careful what your wish for. It was just 90 years ago when the Spanish Influenza became a pandemic. One third of the earths population infected and 10% of those people died.
How quickly would something like that spread in today's society? How many would survive?

It would rise - but not much.
If the entire human population jumped into the sea at the same time, how much would sea levels rise (immediately after the jump)?
The ocean would rise 10^-6 meters, or one micron (less than 0.00004 inches).
However, if all the ice in glaciers and ice sheets melted, the sea level would rise by about 80 meters (262 ft)

Re: The biomass distribution on Earth
I live on a boat. If the sea level rises 260 feet over the next year... I’d still be living at sea level enjoying the view.
