The resources needed to satisfy all the want of human being are said not to be enough compared to all the want of humans we have many want we would like to satisfy at any given point in time which we may not be able to meet up with due to economic problems scales of preference simple is setting our needs inorder of priority.
Human wants are unlimited and obviously cannot be ever satisfied. Human needs on the other hand, can. And I think the mineral resources that are deposited and found on Earth are enough to satisfy our immediate needs if efficiently managed and utilized. I think you’re actually talking about human needs and not wants. We could set up a scale of preference and prioritize our needs in order not to fall into financial ruin.
I can understand why it would seem that resources aren’t enough to fulfill our needs. Governments of various countries who are tasked with managing and putting these resources to good use for the overall benefits of the society end up mismanaging them or even going as far as putting them into personal use.
