This discussion is in the context of a sudden failure of a variety of crops, e.g. <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Death_of_Grass" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Death_of_Grass</a><p>In that context, for a couple or so of years you don&#x27;t worry about soil erosion, except to avoid a repeat of the Dust Bowl, you worry about people not starving.  Before AKA &quot;now&quot;, and after the emergency period, yes, you worry about it, as we do now.
