Non-renewable resources are resources for which there is a limited supply. The supply comes from the Earth itself and, as it typically takes millions of years to develop, is finite.
Renewable resources are those which can be replenished over time by some natural process, including farming. These resources have the ability to be renewed over a short period of time.
Hopefully this helps all I can say is it's probably not money. And I really tried figuring it out but I have no clue.
