UN Special Envoy for HIV/AIDS in Africa Stephen Lewis on Sunday criticized rich nations for failing to deliver adequate aid to Africa, CBC News reports. Lewis also recently launched a book titled "Race Against Time." In the book, Lewis criticizes musician Bob Geldof for using the "hype" surrounding the Live 8 concerts in July to allow the leaders of the Group of Eight industrialized nations to promote a "wholly inadequate" aid package for Africa as a "major triumph of international consensus and generosity," the Ottawa Citizen reports.
