World Poverty and Human Rights: Cosmopolitan Responsibilities and Reforms is a 2002 book by Thomas Pogge. In the book, Pogge explains that the poorest 44% of humankind have 1.3% of global income and their purchasing power per person per day is less than that of $2.15 in the US in 1993; 826 million of them do not have enough to eat. One-third of all human deaths are from poverty-related causes: 18 million annually, including 12 million children under five.
