Season 12
Episode 1203
The corporate farms in central Brazil are the largest in the world. At the periphery, sequestered at the base of a rugged plateau are farms of smallholders who preserve ancient knowledge of seeds, crops and harvest. With the help of scientists, they resist the onslaught of megafarms and harvest their bounty with assistance from nature and hope that their practices will persevere forever.
