Ha! That reminds me of a girl I knew way back when. We were going camping on an island. I had only known her a couple days when a few of us kids decide to go away camping together for a long weekend. We were all like 19-25 years old. That girl looked me dead in the eye and with all honesty asked me "What stops the island from floating into the shore?". I was so stunned I didn't know what to say. A short time later she saw me packing a chain saw and said "Why are you bringing that? Where are you going to plug it in?" (this was back before electric chainsaws were even a thing). She did happen to be blond.
This from FV Ruth & Pat. Local Harpswell Bichrest boys. Lots of fish and everyone was making money. Although that may look like it would deplete the species to extinction it did not. This form of fishing has gone on for 100 years. However now with advanced technology and large Corporations getting involved in fishing things have changed. Yes we can and will deplete the species. This one and many others.
Sorry for the rant.
