“Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your Heavenly father feeds them. . . . Consider the lilies of the field, how they grow: they neither toil nor spin, and yet I tell you, even Solomon in all his glory was not arrayed like one of them.”

Matthew 6:25–34

Trời sinh voi sinh cỏ (Heaven creates elephant, heaven creates grass)

Ca dao Viet Nam

you want to get an idea of the natural fertility of the earth, take a walk to the wild mountainside sometime and look at the giant trees that grow without fertilizer and without cultivation. The fertility of nature, as it is, is beyond reach of the imagination.
