"Any human activity that does not require a large flow of irreplaceable resources or produce severe environmental degradation might continue to grow indefinitely." (Donella H. Meadows, Dennis L. Meadows, Jorgen Randers & William W. Behrens III (1972). The Limits to Growth). Some activities are CO2 negative, like gardening, so they can and should be indefinitely increased.
