Isn't that fascinating? Mother Nature taking care of her own! Much like a canary is used in a coal mine.
Around 1911, miners started carrying canaries into the mines with them, and they quickly became a metaphor for warning signs – when the canary keels over, it's time to evacuate the mine before you become the next victim.source
Native brook trout are very much the canary in the coal mine for the health of a stream.
You are right. Many people who never really drink go on these tours and I found them to be very interesting. Thank you for stopping by and leaving your words.
#MarketFriday loves you!
