I wonder, if we left, how long would it take for the planet to replenish itself. I know vegetation is really good at overgrowing cities in mere years, once people leave.
Depends on what aspect you are thinking of replenishing.
Restoration of the climate until all effects of anthropogenic influences are suppressed? Tens of thousands of years.
Replenishing of full biodiversity lost in the last 15K years? Millions to ten of million years
Replenishing of fossil fuel consumed? Tens to hundreds of million years.
Replenishing of mineral deposits that are continually but slowly formed through geological processes, like gold or nickel? Millions to billions of years.
Replenishing of mineral resources like iron that formed under particular conditions unique to one past age of the earth? Never.
