Soil  has been depleted, exhausted and eroded throughout history, and has  been the ultimate cause of the collapse of almost every civilization  that has come before us, as documented in David Montgomery's fascinating  book, Dirt: The Erosion of Civilizations.  But one of the beautiful and hopeful things about this depressing  history is that soil restoration can take place anywhere. It can be done  one abandoned field at a time.
An example comes from Judith Schwartz's book, Cows Save the Planet And Other Improbable Ways of Restoring Soil to Heal the Earth.  The Loess Plateau in China, an area the size of Belgium on the Yellow  River, was restored in only ten years. It was an almost barren desert  swept frequently with dust storms, and considered by many to be the  "most eroded place on earth."
Now the place is a  "thriving agricultural region with the poverty rate lowered by half,"  writes Schwartz. The local farmers "built terraces, reforested sloping  land (where a good deal of erosion tends to happen) and shifted to  perennial crops that have deeper roots."
Somewhere  along the way, the Chinese government figured out that it would cost  them less money in the long run to restore the soil than it was already  costing them to deal with the constant problems from all the area's  topsoil eroding into the river. But of course, when they restored the  soil, other problems were naturally solved too, like the poverty level  of the inhabitants.
As Montgomery points out, the most fundamental resource of all terrestrial life is soil. Ignore it and we suffer. Take care of it and we all benefit.
