A renewable resource (also known as a flow resource) is awhich will replenish to replace the portionby usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. When the recovery rate of resources is unlikely to ever exceed a human time scale, these are called perpetual resour.
