KARACHI – Fourth annual letter highlights progress in developing countries, outlines new approaches to help poorest build self-sufficient Bill Gates, co-chair of the Bill & Melinda Gates Foundation, challenged global leaders today in his fourth annual letter to invest in innovations that are accelerating progress against poverty, or risk a future in which millions needlessly starve, says a press release.

The letter describes remarkable progress in the developing world and makes the case to continue investing in efforts that have made a difference for millions of the world’s poorest people. Over the past 50 years, for example, the percentage of the population living in poverty has fallen from 40 percent to 15 percent, or about 1 billion people.

Gates believes it is possible to continue the progress, but only with innovative investments in areas like helping small farmers grow more food, which is the best way to fight hunger and poverty among the poor.
