As stated earlier, it would be a slippery slope to prove. But I've increasingly wondered about the environmental impact of all these "bubblers" ( :-), I'm from New England) keeping the shoreline open year round when it used to freeze regularly.
What is the impact on fish and other species who depend on the freeze cycles and undisturbed sandy bottom? What about the spread of invasive species or the fact that they are not killed off by a freeze? Etc...
There may be no impact, and like other environmental issues, would probably be impossible to prove, and more impossible to defend. But I personally wish that they would be banned. With modern raise-style docks, how hard would it be to have a removable dock instead of keeping circulators running att the time?
