European and American agriculture started with grazing cows and growing grapes for the king and the church. They changed nature by doing this, especially on the hill slopes. Then soil erosion occurs. Because the land is depleted, they need chemical fertilizers and pesticides. United States, Europe, even in Japan, their agriculture started by tilling the land.
Cultivation is also related to civilization, and that is the beginning of the mistake.
True natural farming uses no cultivation, no plow. Using tractors and tools destroys the true nature. Trees' biggest enemies are the saw and ax. Soil's biggest enemies are cultivation and plowing. If people don't have those tools, it will be a better life for everything.
