Throughout history, civilizations have risen or fallen depending on the fertility of their topsoil.
Great civilizations have fallen because they failed to prevent the degradation of the soils on which they were founded. The modern world could suffer the same fate. This is according to Professor Mary Scholes and Dr. Bob Scholes who have published a paper in the journal Science, which describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.
