Chapter 2 A History of Unsustainability in Agriculture Abstract Throughout history, farmers have sought to maximize yield, because growing bumper crops gives them a competitive advantage over their neighbors. Nations have sought to maximize agricultural yield, because it gives them an economic advantage in the world marketplace.

The El Yunque National Forest in Puerto Rico provides an example. This montane forest is frequently hit by hurricanes. While wind may knock over large trees, seedlings and saplings are limber. They bend but do not break, and respond quickly with increased growth following destruction of the overstory canopy. The amount of rain that falls is more critical. With heavy amounts of rain , the soil that sits like a blanket over the rock below begins to slide. In the upper part of the landslide where the saprolite (chemically weathered rock) is exposed, forest recovery is impeded, but in the lower part where soil from the slide accumulates, recovery is more rapid (Guariguata 1990).
