Renewable: somthing that can be renewed.

Renewable resources are any type of resource that can be regenerated at a rate that is at least equal to the speed with which humanity can consume that resource. While considered capable of replenishment over time, resources  of this type usually require some degree of planned and responsible cultivation and harvesting in order to insure the  resources  are available for future generations. Wood, leather, and plant life are examples of renewable resources.
