Indeed the impact of agriculture can not be over emphasized hence it's  role of sustainability is visible globally.  Any society that ignores the source of food is directly heading towards hunger and scarcity because humans need food to sustain.
   Worthy of note, the primitive era explains it all the importance of agriculture, you will agree with me that during that era when there was no industries and machines for processing agricultural produce individuals were still sustained through trade by barter and people with vast agricultural extension gained wealth and fame through it.
   Unfortunately, some society leaders around the world has neglected the  tremendous wealth agriculture can generate within a short time. Most 3rd world are ceaselessly running into debt with other western nation because it's govt choose to neglect agriculture as a food and wealth bank which ought to be sustainable to them.
 My conclusion is that the level of attention given to agricultural sector  by a govt determines if such society will escape a reoccurring recession or not.
