Instructions
It  is  thought  that  around  12,000  years  ago  the  Earth's  climate  became  relatively    or  more  temperate,  allowing  for  a  greater  variety  of  plant  life.  Those  early  humans  leading  a  nomadic  life,  who  hunted  and  gathered  food  where  they  happened  to  find  it,  began  to  supplement  their  diet  with  wild  grasses  such  as  wheat  and  barley.
Noticing  how  discarded  seeds  and  roots  later  germinated  and  sprouted  may  have  been  what    the  first  farmers  to  settle  down  and  cultivate  crops.  We  know  that  farmers  in  the  Stone  Age  had  discovered  pulses  -  beans,  peas,  lentils,  and  so  on  -  which  they    up  and  ate  as  a  kind  of  porridge.  Later  they  learnt  to  domesticate  sheep  and  goats,  developing  tamer  and  manageable    of  these  and  other  animals.  In  addition  to  that,  they  also  discovered  how  to  use  the  process  of  fermentation  for  brewing  and  making  bread.
It  was  some  time  later  that  farmers  noticed  that  the  amount  of  crops  produced  declined  if  they  were  always  grown  in  the  same  ground  and,  by  the  1st  century,  the  Romans  were    crops  with  pasture  for  grazing  animals  to  restore  the  soil's  fertility.  This  practice  was  followed  in  medieval  England  where  the  fields  were  divided  into  strips,  planting  cereals  and  vegetables,  and  the  land  left  uncultivated  one  year  in  three.
