.......uhm, . but there ARE new crops of barnacles to be found.......... right.......?
.....so at least I'm not looking for a needle in a haystack that isn't even there..?
Hopefully, but it wouldn’t be the first time humans have destroyed something by over utilisation look back over history Kansas dust bowl, North Sea Herring fishing, the Passenger Pigeon, the Dodo and even further back Unicorn hunting (though to be fair that was put down to a lack of bait).
But you cannot know the needle wasn’t there until you have searched the haystack.
