World hunger is bringing together leaders in Rome this week for a United Nations Food and Agriculture Organization food security summit. Director general Jacques Diouf calls world hunger – the kind that’s now killing a child every six seconds in an underdeveloped country – “a moral outrage, an economic absurdity and…a serious threat to our collective peace and security.”

Where can we start to address this issue? How about with plants? That’s the topic of my Urban Cowboy column this week in the Guelph Mercury.

Diouf orchestrated a one-day hunger strike as a prelude to the summit. FAO photographer Giulio Napolitano captured the image of Diouf at the strike, below.
