The words are Gary North’s: I’m bolding the money shot.
The culture that economic change produces in a profit-seeking society in which the private property system prevails is dominion-oriented. The earth is subdued, if not because men aim at subduing it for God’s glory, then at least for individual profits. The general dominion covenant is furthered. By fostering conservation, the quest for long-term returns from the ownership of any productive resource also tends to preserve the productivity of the earth. The dominion covenant is not to serve man as an excuse to destroy the earth. Because men failed to give the land of Israel its rest, they went into captivity for 70 years (II Chronicles 36:21). They were warned not to misuse the soil.Gary North, in Chapter 15: Diminishing Returns, of Christian Economics: Scholar’s Edition
