Is Poland's tap water really protected by clams?

I went to a lot of effort to prove this, but it's like Carl Sagan said: extraordinary clams require extraordinary evidence.

The Polish scientist describing the clams as "colleagues" was such a sweet turn of phrase.

I'm stupid, I started reading the subtitles for when the polish started and only 30 seconds later realised that I in fact do speak and understand polish fluently

"we take care of our colleagues" when talking about the clams safety is gold

[Hotlooksamerica]

People used to keep a canary in the coalmine,
Warsaw water department keeps clams in the turbine.

"Because we take care of our coworkers" is the best line ever and shes so proud of that fact so wholesome

[PinkoLP]

"So I worked in water quality assurance once..."
All the other clams: "Oh, shut up Jerry!"

The analogy of it being another layer in their security, like a bomb sniffing dog in an airport, was wonderfuly said.

I love that you are willing to go through all the effort and research and hard work to prove to us that Poland is indeed testing their water with clams! Such an interesting story, i'd never heard of it before but it does make sense. Thank you for taking the time and effort to create this and know that you and your work is loved and appreciated!

Her calling the clams 'colleagues' is just the best! 😊

Fresh water clams are amazing creatures, unappreciated for their contributions to their local environment. Once abundant in the many rivers and streams of North America, today they are not as easily found. As prodigious filter feeders, they effectively kept the water clear and can be used to do the same in aquariums. The trouble is, mollusks are unusually sensitive to chemical pollution, often dying after exposure to concentrations that won't harm fish.

As a Ukrainian speaker, watching the Polish interview was a delightful mix of “oh, I can understand that!” and “huh-”
It does not help that Polish for “contaminated water” is literally Ukrainian for “crazy/rabid water”😂

[johnchessant]

imagine being one of those clams returned to the water after three months ... it'd be like they got back from an alien encounter, absolutely wild

[Ntmoffi]

As someone who works for a water district I find this absolutely fascinating.

I've actually completed studies in Łódź, Poland with Biomonitoring specialization, our country slowly but surely implements those kinds of enviroment monitoring in various places

[jobal]

In Poland, the small municipality of Zmigrod also tests water purity this way

[pyglik]

It's so weird to be watching Tom Scott's video and have to switch from English to your native language! Nice to see you in Poland!

[dahgnzg]

Finally a topic I already know something about, in Poland schools they taught us that clams require a very specific enviroment which allows clams to be a tester for water as they are very vurnerable to enviroment changes, unluckily they can only live in healthy bodies of water which gives us the ability to determine in what state the water is.

Love from Poland. I'm old fan excited to see you in Poland!!

[Gringottone]

Great video, really appreciate how wholesome you made the whole thing. Keep it up!
