Aside from possible toxicity to the animals (like how onions are toxic to cats), I think the enormous quantity is a big problem. The crabs, etc. just couldn't eat enough of it, fast enough, to prevent the sea becoming nasty. I suspect also that the rotting food would consume oxygen in the area, and that would kill some sea life.
