This requires energy and resources on our part. Monoculture tends to reduce soil fertility as a continuously planted species will quickly deplete the soil of the nutrients required by that species. Farm fields are planted in organized rows to facilitate planting and harvest. Farm systems are very simple ecosystems , with as few as one plant type and few parasites.
Simple ecosystems are more susceptible to collapse and undesirable change.
Plowing is an unnatural disturbance which exposes soil to erosion and can damage its physical structure. Economic demand usually exceeds production, making food prices higher. This forces a greater reliance on aquaculture . The removal of crops short circuits this natural cycling and requires the addition of fertilizers. Without continued addition of nutrients, plant growth is limited by some combination of limiting factors.
