What is the most important question in the world?

If you're not already aware of the Conversation Cafe movement, you might want to have a look!

At the end of this month Conversation Week 2008 will begin, and people around the planet will meet in cafes and in homes to talk about the voted-upon picks for top ten most important questions in the world today. What do you feel is the most important question in the world, and why?

(And yes, we'll certainly be asking some of those questions here—both those ones voted on for this year's Conversation Week and the ones you come up with.)
