At least 30 Nobel Prize winners, including former Soviet leader Mikhail Gorbachev, will meet in the ancient city of Petra on June 17-19 to discuss global problems. One of the main topics at their meeting is food security. High food prices have increased hunger and poverty and produced rioting in some countries.
