no water does not apply
i probably a should have elaborated on "end world hunger"
food basically becomes as plentiful as the dirt on the ground. i cant exactly explain how, but it just is. Maybe the world is like the willy wonka forest where everything is edible? Maybe a scientist invented a device to turn basic particles into full course meals with no cost? The point is, everyone in the world has access to any sort of meal possible. Yes, this means farming is obsolete. As for water goes, Im pretty sure there are plenty of natural foods out there that replenish thirst if you live somewhere where water is not a resource.
