+1 to The Land Institute. To give others context, perennials require much less input than their annual cousins, both in terms of labor and also petrochemicals.

+1 to The Land Institute. To give others context, perennials require much less input than their annual cousins, both in terms of labor and also petrochemicals. The other big benefit is carbon sequestration. Perennials typically root far deeper into the soil, giving prairies enormous amounts of (carbon sequestering) root mass. This also has benefits in terms of erosion control — soil loss is one of the biggest, not talked about threats to society. Finally, perennials can help — again through extensive root systems — improve water capture, recharging aquifers.
