Would regulations work on this situation?
If there is that many in the fleet, there's a market a couple billion or so hungry people and you won't easily stop it, only push it from place to place, clear the way for the next fleet.
A private entity or country could always take matters into their own hands. That fleet parked on the edge of Galapagos looks like a good target to me, but all the fuel and who knows what else on board would spil there near the Galapagos if you blasted 'em.
Someone have a better idea? Waterboarding? Chop-sticks confiscation? Nope.OK Use an Armada of inflatable Unicorns, supported by an army of pissed off Mermaids to force the fleet off the edge of the Flat Earth!
Bohter to the Bat-phone please.
