Well, what if we switch to electric vehicles instead of conventional ICE vehicles? Electric vehicles require some limited natural resources, as well, such as copper and rare earth metals, for electric motors, and lead and lithium, for batteries. While the rare-earth metals might last until nearly 2090, the copper might last just shy of 2040. Lead, on the other hand, might not even last until 2025, a mere ten years from today. Unless we institute some pretty radical recycling programs, electric vehicles might be a pipe-dream after 2040.
