The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

The weight of the trees was so great that the ones on the bottom got squished and became coal. That’s where coal is from. Bonus fact: the whole time this was happening, sharks were hunting in the oceans. Sharks are older than trees and fungus!

Fungi in general are about twice as old as sharks. Roughly a billion years vs ~450 million years.

The point is there just weren't any which had bacteria to decompose trees, as no bacteria had evolved the ability yet. Until there were. Took millions of years though.

Fun fact, now we have mushrooms which can deal with plastic.

Pestalotiopsis microspora is a type of endophytic fungus discovered in the Amazon rainforest in 2011 which contains bacteria that can biodegrade and break down synthetic plastic polymers.

that's what i was thinkin... surely single-cell eukaryote (fungi) is earlier than complex eukaryote (shark)?

[–] [email protected] 17 points 5 months ago

you'd think so, but sharks were in fact the first lifeform to be summoned from the astral planes, everything else evolved from a single shark cell that had the right mutations to survive (all sharks simply died within minutes until plants had created enough oxygen for them to breathe, at which point they died within days until the evolution of other animals)

Thank God for fungi. They do so much for us and now eating plastics. We really need something to eat it all

[–] [email protected] 39 points 5 months ago (1 children)

There's also fungi which can use radiation as a source of energy, radiotrophic fungi, and we've been thinking about using them as radiation shields in spacecraft.

The reputation cordyceps gave fungi is really unfair IMO, they mostly chill shroomy buddies that poop food and eat poop

[–] [email protected] 4 points 5 months ago (6 children)

cordyceps are to fungi what barnacles are to arthropods, horrifying twisted versions of the clade

Is this a good thing? Consuming plastic means releasing all the carbon that they're made of.

[–] [email protected] 14 points 5 months ago (1 children)

Awesome, now they'll just dump all the plastic in the Amazon and congratulate themselves for doing the right thing

Fungi are pretty awesome. We can decompose plastic with them. Engage in inter dimensional astral travel with them. And have a nice trip by a campfire without ever leaving the chair.

[–] [email protected] 4 points 5 months ago

At some point this will happen with plastics too. Soo much plastic is ending up in nature, with soo much energy ready for the taking. When one fungus or bacteria mutates just right to munch on that feast of plastic, that vast energy source will ensure that organism multiplies rapidly.

And that is when plastic stops beeing useful for many of the tasks we humans use it for. If your plastic container decomposes as rapidly as a cardboard box, it will quickly become much less usefull.

[–] [email protected] 46 points 5 months ago

There are already organisms which can digest certain plastics. The problem (AFAIK) is they can digest other stuff more easily. So maybe in landfills ill work, not so much in nature were there's other organic matter for the taking.

[–] [email protected] 29 points 5 months ago (2 children)

If your plastic container decomposes as rapidly as a cardboard box, it will quickly become much less usefull.

How so? Plastic would retain its current properties, just something may break it down over time. Wood is still useful after all.

[–] [email protected] 42 points 5 months ago

Cardboard boxes last almost indefinitely in a cool dry warehouse. It's not just a matter of time, but the environment that matters.

[–] [email protected] 9 points 5 months ago

It would depend on how well we can control it.

Ideally the material would be completely nonreactive for as long as you're using it and then instantly degrade into component elements.

The faster things degrade, the higher the chance that they'll degrade when you don't want it to.

[–] [email protected] 13 points 5 months ago (1 children)

Well the carboniferous period lasted 60 million years. If life takes even a fraction of that to figure out plastics, humans will be long, long dead by the time they do. But I'm sure it'll be something interesting for future non-human civilizations to ponder over.

[–] [email protected] 15 points 5 months ago (1 children)

Speak for yourself there, buddy. I plan on being around for at least another 82 million years. I'm uploading my brain into a terrible android as we speak.

[–] [email protected] 3 points 5 months ago (1 children)
[–] [email protected] 5 points 5 months ago (1 children)

It was the only one available. I'll upgrade in a few years, probably.

[–] [email protected] 2 points 5 months ago (1 children)

Can you just buy a new one in a few years and have two?

[–] [email protected] 2 points 5 months ago (1 children)

I guess it depends on how much money I can make as Texas, the Drunk Android.

[–] [email protected] 2 points 5 months ago (1 children)

Probably a lot. But also more than double if you duplicate your consciousness into a second android.

Shit, you sold me. Where can I get a cheap android to upload my consciousness into, so I can make them slave 80 hours per week for me $$

[–] [email protected] 2 points 5 months ago

Unfortunately due to capitalism I can't tell you or it'll cut into my money and thus ability to live for millions of years. Once I've made my money I'll DM you so that you're second in line.

Fortunately we've always had a solution: just fucking use glass

Bonus fact bonus fact: Shakes are older than the rings of Saturn.

You did a great job in the Star Waes prequals, btw

[–] [email protected] 26 points 5 months ago

I would've guessed milkshakes were invented in like the 1940s

[–] [email protected] 18 points 5 months ago* (last edited 5 months ago) (2 children)

I use this regularly use this as an example/precedent of a previous macro-cancer of the natural world that was detrimental to Earth's ecosystem from a mistake of evolution.

The trees removed too much carbon from the atmosphere, leading to an Ice age.

We homo-sapiens are just doing the opposite. 🔥

Don't worry though, our mother eventually found a solution to the tree's carbon capture problem, and I have every confidence she will find a solution to us and in a few million years, nothing to her 3.8 billion year old story of life, she'll finish cleaning up our mess. Problem solved, life will flourish, and new ecosystems in homeostasis with the Earth will develop... until the next macro-tumor of the natural world, at least.

if trees survived their self-inflected apocalypse, why can’t we?

[–] [email protected] 12 points 5 months ago (1 children)

Oh humans will survive, no problem. I mean, not a lot of them and not happily, and there will probably be a nuclear war at the end there, but humans won't go extinct. We're too smart to not find a nice hole to hide in.

[–] [email protected] 3 points 5 months ago

Millions is fine. Its a lot. Billions is just crazy and never should have happened.

[–] [email protected] 9 points 5 months ago (1 children)

Trees breed by putting their babies into extremely resilient, heat and cold protected stasis pods that can go centuries without care and attention in the right conditions - like suviving an ice age or forest fire.

Human babies are wimps by comparison - most of them would die after only a few days left outside at 0 degrees C.

Humans probably will survive too - but how many?
Elon + all this 3 mates.

[–] [email protected] 3 points 5 months ago* (last edited 5 months ago)

Yeah, I freeze my spurm and I'm pretty sure there's a few thousand different women on this continent who have frozen eggs

[–] [email protected] 3 points 5 months ago* (last edited 5 months ago) (4 children)

They didn't know what they were doing, we do, and we actively choose to keep doing it. Unlike those trees mindlessly performing a base biological imperative, we possess the capacity to stop and simply don't because we'd lose some of the comfort and convenience our destructive tech provides.

We're cruel to this planet, all the other creatures on it, and one another. So my reverse ask is, why do you want us to survive? Just because ra-ra home team? Because billions subsisting to serve the whims and ego of a few thousand of our worst, most broken, greedy sociopaths in perpetuity is somehow meaningful? Genuinely asking.

[–] [email protected] 11 points 5 months ago (3 children)

I don’t understand why you believe there is a difference between choosing to continue destroying the world and just “destroying the world”

Nah we can just blow up the planet, take that mother nature

[–] [email protected] 4 points 5 months ago

The moon did that a long time ago. And here we are today.

[–] [email protected] 8 points 5 months ago (2 children)

The trees clogged the land, the water, and when one inevitably got struck by lightning, continent wide forest fires were common.

IIRC, it's these trees, not dinosaur bones that became most of the oil/gas deposits.

It's worth noting that when it comes to a species wrecking the environment, causing mass extinction, changing the climate, or spoiling the atmosphere, humans are not the first and we're not the worst.

[–] [email protected] 2 points 5 months ago

We are (probably) the first to actually be (mostly) self-aware of it though. As in we could do something about it.

Oh noooo, the coal existing because of evolutionary lag theory is one of my favourites. Continents colliding and creating wet topical basins is cool too, but it’s not such a good story to tell.

[–] [email protected] 2 points 5 months ago

I agree. Total bummer.

There were shrooms, they just couldn't eat carbon

[–] [email protected] 2 points 5 months ago

Whoa, good fact! Thanks
