What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Early New Yorkers tossed garbage into the street or into one of the rivers. The city stunk. In the absence of organized waste disposal, pigs played an important role in reducing (and reusing and recycling) trash in the city.

Brought to America by European colonists, pigs were commonplace and an important source of food. Without room to house them, hogs were largely left to roam the city foraging for food scraps, which not only kept them alive but also removed waste from the streets. By some estimates, upwards of 20,000 pigs free-ranged on the streets of Manhattan in the early 1820s.

I wish they acted as street cleaners.

Then, in 1832, they started spreading rabies, so they were all butchered. That's how the tradition of Christmas ham got its start.

I also have a monorail I can sell you.

Is there a chance the track could bend?

[–] LemmyKnowsBest@lemmy.world 3 points 4 days ago

Hello sir, I am interested in purchasing one monorail please.

Was it really less stinky once the waste is transformed into pig poop?

[–] Mighty@lemmy.world 34 points 5 days ago (2 children)

Yea, because pigs don't poop where they eat if they have enough space. They will designate a pooping place for their pack(?), which makes it easy to clean

Something something New Jersey [cue laugh track]

So, free trash collection with extra steps?

[–] Triumph@fedia.io 10 points 5 days ago

There was already a system in place to clear the horse manure, the pig manure just went with it. You can fertilize with manure, less so with trash.

[–] Etterra@discuss.online 6 points 5 days ago

So who cleaned up the pig shit?

[–] optissima@lemmy.ml 7 points 5 days ago

On May 23, 1845, they formed a municipality, today ~34,727 pigs roaming NYC¹

What stopped people from snatching them up and eating them?

[–] snooggums@piefed.world 16 points 5 days ago

The same thing that keeps people from stealing all the free cows in fields by the side of the road.

Time, effort, and threat of punishment is enough to discourage most people who consider stealing stuff and pigs are a whole lot of work to steal and eat.

[–] Jimbo@pawb.social 3 points 5 days ago

You ever tried to chase a pig?

[–] Proprietary_Blend@lemmy.world 3 points 5 days ago

How many are on the force now?

[–] IWW4@lemmy.zip 3 points 5 days ago

And add to the richness of the aroma, everyone used outhouses as well.

[–] mossberg590@lemmy.world 1 points 5 days ago

Germ theory only took off in the 1850s. Just bear that in mind.
