Livestock, agriculture, silviculture, beekeeping, and all cultures should be mixed. That way, the organic waste is reused without polluting the water table. The variety of crops does not impoverish the land but enriches it, nourishes livestock, bees pollinate the flowers, birds eat harmful insects, etc in nature.
This is the most modern and least harmful way and infinitely more profitable, as did the Indians, who were infinitely more advanced than the spurious colonizers.
What is a crime against nature and humanity is today with monocultures where the land is poisoned, soils are eroded, water is polluted.
