Fix the Soil First: Soil → Crop → Animal → Human
Cho opens the advanced seminar with questions, not recipes: what is nature, who are you, what is the biggest farming. He argues that health comes from healthy food, so the farmer is the foundation of the world, and that farming by your own judgment or a professor's theory makes 'smart fools'. He ends on the chain soil welfare, crop welfare, animal welfare, human welfare, written on the flip chart.
