When a poor country is hit with a sudden catastrophe — say, an earthquake or a tsunami — the world is quick to send aid.
But a slow-moving disaster, the kind that unfolds over weeks or even months, is another story. There are no immediate, dramatic TV images, no screaming headlines.
And that means it's really tough for aid groups to raise the money needed.
Just ask John Graham. He's the head of the aid group Save the Children, and he's watching a slow-moving disaster unfold in Ethiopia as the world remains largely oblivious.
