Natural Resource
Anything humans obtain from nature that is useful or economically valuable
Renewable Resource

Ex: Solar Energy

Ex: Coal
Crude Oil
Copper
Iron
GoldSustainablility
The practice of using a resource at a rate that is less than or equal to the rate at which it is naturally replenished
Ex: A cow eats less than an inch of grass a day and the grass grows one inch a day.
