Those are all renewable.
- evan_ 5y agoso is petroleum, if you can wait a few hundred million years
- sokoloff 5y agoFossil fuels probably are as well if you’re willing to wait long enough. No amount of waiting will renew one of the extinct species listed.
- celticninja 5y agoI dont think this would apply to coal. There are organisms that can use the wood that would otherwise need to fossilize to create coal. These organisms did not exist the first time round.
- chasil 5y agoDo we have a viable genetic sample of slphuim to grow it again? I certainly did not think so. "The plant grew along a narrow coastal area, about 125 by 35 miles (201 by 56 km), in Cyrenaica (in present-day Libya)." https://en.m.wikipedia.org/wiki/Silphium_(antiquity) https://en.m.wikipedia.org/wiki/Silphium_(antiquity)
- SamReidHughes 5y agoI meant that in the sense in which it is true -- all of these things self-replicate. Up until we ran out of them, they were renewable.
