I love this idea and how they execute it. Catch the clams, give them proper cares, and once they finish their service of 3 months, they go back to their home. Something I never even heard of, but I got one more reason to like Poland now,(reply>), @TheBirchCreek if my memory doesn't fail me and system in Warsaw is built the same way as in Poznan, clams are checking water after filtration and oxygenation, but before disinfection process. And they are not fed.,(reply>), @Laszer271 Its bold of you to say that, look at countries around Poland and their economy, history in general, you can't say whole country is unlikable because you got bullied in school,(reply>), @Stay High That's how I know :),(reply>), @Laszer271 you must be polish 1000%,(reply>), @Idź Idź I believe I wrote that it's questionable. There is almost nothing you can prove with 100% certainty.<br><br>Then there's also the argument from the side of what is even evolutionary incentive for a clam to have consciousness. Any system developed for this function would be waste of resources. Same with plants. They can not pick up their roots and leave. :D
