Well, I agree that it’s not a good idea to sell swimming pools with sharks in them. In marketing their pools Folkpool is pointing at the fact that oceans have sharks and that it is therefore not safe to swim in the ocean. Their solution is of course to buy a pool instead since they are shark free (great point).
What not so great is that in their postcards you can see an authentic great white shark swimming beside a kid and that feels a bit unethical.
