The abundance, biomass, and distribution of ants on Earth

Here's a fun fact. The desnity of humans is roughly that of water (1000kg/m^3). Humans are 18% carbon so humanity's mass is 333 megatons. If we squished everyone into a sphere is would only be 860 meters across.

trying to find a favorite, how about
"It's about 150,000 times as heavy as The Space Shuttle"
> ...a biomass of ∼12 megatons of dry carbon... equivalent to ∼20% of human biomass
Honestly the unfathomable biomass of humans creeps me out more than the biomass of ants...
We use most of the Earth's dry surface to feed ... What ever that picture shows.
Disclaimer: I did not check their math, but it is in the right ball park.

We don't even come close to using 10% of the earth's dry surface for food production, let alone most of it.

We'll be squeezing out pretty much all remaining wildlife in a few hundred years,
You may want to pass on that, it's right at the top of that reddit page.

I was thinking 100,000 range tops. They real are tiny.
That's a lot of biomass!
I find awe in the way they interact and accomplish tasks as a whole colony that would be impossible for any single individual. And how some species have developed complex, specialized behaviours from the various Acromyrmex species that farm fungi or the genus of Solenopsis that build bridges over water. And they're fascinating to watch!
The idea that a single individual may not have the neurological framework to manage these complex behaviours that enable colonies to remember and optimize paths to sources of food over time is fascinating.
Formica Rufus! They have a caste system of workers. They farm aphids and plants, they have hunters, and they have builders. They build huge mounts out of deciduous and coniferous plant material around fallen trees. And yet rigid seeming as they are there have been observations where individuals within a caste that prefer certain kinds of tasks over others.
I really like spiders too but ants were my first fascination and I still really enjoy them. My kids and I love to catch and identify queens of various species in our area during nuptial flights. It's a lot of fun... sort of like real-like Pokemon.
It’s amazing. Obviously we need to get rid of ants and introduce the ladybugs to help out cherry tree.
I am sure there is a natural way to do this but I am obsessed by their collective consciousness.
So humans are not mammals anymore?
Would it be possible to see that map without shelling out the $10? The people need to know!!!

They don’t count humans as mammals?
I guess pets as well were excluded
Err, ok? What's the 'correct' number of humans on this planet, and who decides who gets to live and reproduce?
So while a 6'x6' space isn't a lot, you could fit the whole population of the earth in just one area with plenty of room around each person.
I think politics and greed are a bigger cause of starvation and pollution than population size.
Interesting model. What does it tell you that starvation has been trending downward for decades?
No one decides about it for now, like we do for other invasive species, but we should probably start considering regulating ourselves
This is a nice “wow” statistic, until you look at how few wild animals are left.
Puts thoughts of living off the land, surviving a collapse of our food chain, obsoleting animal husbandry etc out the window.

I think Google has now mostly stopped with the brain teaser questions but I could absolutely imagine this being one back in 2010 or so!
This was, I believe, a Microsoft interview practice. Questions such as "how many golf balls can you fit in a bus?" and "how many piano tuners are in Chicago?"
Google engineering interviewing doesn't work this way and I don't think it ever did.
And that's how the Windows Update team was selected /s
BTW, the "See also" section in Wikipedia is funny, it even includes the spherical cow concept: https://en.wikipedia.org/wiki/Fermi_problem#See_also
Also Edison, General Electric early on (like lightbulb era), had (according to one source, but it makes sense) like a prototype of an IQ test, tested memory and general knowledge. Basically how much you had read. By that point America had ample libraries thanks to Carnegie, so it was fair, before that there was no way.
Makes sense since Edison and Gates dropped out. And back then college dropouts were too educated, so for instance JP Morgan did a year in college, traveled a bit and that completed his education. I dropped out recently (technically an impasse, glitch meant I couldn't enroll again) and with that my education is complete. But back then? Dude nobody finished high school, Ford didn't, Wright Brothers said eh, like back then if you went to college you were badly overeducated.
So the "how many piano tuners are there in Chicago" question is a sanitized version of "how many kilotons of TNT did this nuclear bomb yield?". Fermi problem, I think it's called, and Fermi was great at it, got it to within a factor of 2. Wright Brothers also nailed it very well, like got 1% margins on admittedly easier math than the bomb, but with their other invention, the wind tunnel, and very very low resources initially. So the piano tuners sounds like a stupid question, otherwise it would require that special nuke clearance, get real. And it's the same thought process.
I believe those came out of microsoft interview questions from the 90s? Or at least that's how they were referred to, maybe it was just a meme.

A family is getting a tour around a museum. The tour guide points to a T-rex fossil and said "That dinosaur is 75 million and 4 years old". The guest says "Wow, so precise!", and the guide says "Yes, it was 75 million years old when I started, and I've been here for 4 years".
> "I'm not afraid of insects taking over the world, and you know why? It would take about a billion ants just to AIM a gun at me, let alone fire it. And you know what I'm doing while they're aiming it at me? I just sort of slip off to the side, and then suddenly run up and kick the gun out of their hands."
Never fear, friend.
