Tim Keegan, a Global Farmer Network member from Mount Vernon, IA, explains the high stakes in agriculture, emphasizing that farmers get only one chance a year to raise, market, and sell their crops.

He discusses how tariffs impact his family farm and others in this CBS Evening News story, "U.S. farmers react to China's retaliatory tariff increase."
