Lumber, Food Crops, Food Animals = Renewable
Diamonds, Heating Oil, Copper = Not Renewable

Diamonds and Heating oil are carbon products--both created by millions of years of earth forces. Copper is a metal (and an element) and is also not renewable.

Nothing is renewable if there is a limited, fixed supply to what already exists.

If something is alive & can reproduce, then it can be farmed or raised, so .....

Diamonds are an interesting question. At one time it was only what diamonds could be found in the ground. Today, diamonds can be manufactured in a laboratory. Hmmmmm.
