 Over the 50 years since I sat in the UC Berkeley Library pondering the root causes of hunger, I've tried to keep digging into the question beneath the question to help me grasp why we humans have messed up so badly. And here's the deepest question my digging has turned up so far. Why are we together creating a world that, as individuals, none of us would choose? After all, I've never met anyone who gets up in the morning vowing to make another child starve or to turn up the planet's temperature.
