Estimates of early Native American hunter-gather societies indicated that a person could
kogti [31]

Other assumptions associated with this question are as follows:

  • One person can feed on 1 hen/day for a year
  • 1 hen must east 25 grasshoppers /day
  • the total mass of 1000 grasshoppers is 1kg
  • 600 grasshoppers are needed to feed 1 human per day

Grasshoppers is represented as Gh.

The total amount needed to feed the hen per year is:

  • 25 x 365= 9,125 Gh/Year
  • If expressed in Kg, then it would be 9,125/1000 which is
  • = 9.125Kg/annum.

So if the farmer chose to live on grasshoppers rather than on hens, the calculation is given as follows:

  • (90 kg/1 hour) x (24 hours/1 day) x (1 person/ 600 Gh)

The amount of Grasshoppers required is given as follows;

If the farmer can gather 90 Gh in one hour then,

  • The total amount of Gh per day is 90 x 24 = 2,160
  • the total amount of Gh available in a year is 2160 x 365 = 788,400 Gh/Year
  • If 600 grasshoppers are quired to feed the human per day, then we work backward
  • The total amount of Gh available in a day is 788,400/365. This is equal to 2160 Gh
  • The total amount of people this can feed is given as 2,160/600
  • Which is equal to 3.6 persons.

Since humans or people cannot be divided into fractions like a measure of sugar or a measure of liquid, the answer is best left to the most approximate digit with it 4 Persons.
