World's biggest challenges

I found this interesting ... last month's LeaderValues poll question was:

What are the world's biggest challenges today?

And the answer surprised me a little ...

• Global poverty 34%
• Inadequate political leadership 21%
• Environmental sustainability 15%
• Terrorism 13%
• Cultural prejudice 10%
• Business globalization 4%
• Other 2%
• Ethical dilemmas in science 1%

I can't argue for the scientific nature of the poll, although I do know it is a global audience. And maybe it is the power of the recent publicity on Poverty and the Live8 impact ....

But maybe the concern is real? Anyone know? Views?
