Why? Because we don’t have promised underwater colonies that was predicted in the 19th-fucking-century before ANY of us were around and STILL not here.
Because it’s apparently *too damn hard* to come up with a simple multi-layered animal filtration system which allows any trapped animals a channel where they can enter and then leave of their own accord without getting caught up in the deeper levels, like an ‘animal sieve’ so that by the time it gets to the turbines, we’ve barely lost ANY current and managed to save all but the smallest of fucking PLANKTON…
..and because I make everything sound EASY because I don’t have to deal with the logistics of implementation, funding, pushing back against well-organized energy suppliers who themselves are probably not dangerous but all it takes is ONE CRAZY INVESTOR in my home state of New Jersey to get it in his head that he might have a 2 penny drop in his or her natural gas distribution trucking company and decide to hire cousin billy to poke a few holes in my scuba gear…
=====
And – to keep the animal filtration system from clogging up, hire scuba-diving animal lovers, give them residence and responsibility. Also, hire people who love space sci-fi to populate underwater colonies with vague promises of “this is training for our deep space program”, pay for residence and responsibility to keep the turbines functioning.
There. Done.
