  • 47% of the Mexician' diet is corn
  • it takes 2.4 pounds of corn a day to feed a hungry person
  • it takes 22 pounds of corn to make one gallon of ethanol
  • there are 42 gallons of refined gas in one barrel of oil
Now, a little basic math can be very enlightening. To replace one barrel of oil, it takes 42 gallons of ethanol or (42x22)=924 pounds of corn. That is enough corn to feed one hungry person for (924/2.4) 385 days - a little more than one year.
