Yes, absolutely. The supersaturated brine produced as a byproduct decimates local ocean life when it's pumped back into the ocean. It's already a problem while desalination is rare. Imagine how bad it will be at "human-scale". And you can't just divert the brine onto land. Where ever you put it will be salted earth - completely unlivable. And it will probably pollute ground waters.
