An ear of corn....or a corn field

For all of you agriculture folks out there...

I think you'll enjoy seeing how Lifesong for Orphans is helping develop crops for the children at the Lifesong-School in Zambia, while teaching them work ethic at the same time...

Borrowing from the old adage: 

Don't just give a man an ear of corn, give him his own corn field!

Why can't we do this in more places in Africa?
