That's entirely renewable when it's done with human labor. Renewable doesn't mean "one with the earth" or whatever hippy-dippy thing you think.
Fossil fuels on the one hand allow deforestation on an unimaginable scale but also allow artificial accelerated regrowth with mechanization and fertilization.
Also, what "vast" swaths of land were deforested before coal power or oil power that threatened all of humanity or were not regrowing within a generation?
