The net effect of all these changes, Pogge calculates, is that, whereas world leaders pledged in 1996 that by 2015 they would reduce the number of undernourished people to no more than 828 million, now they are pledging only to reduce the number in extreme poverty to 1.324 billion. Since extreme poverty is responsible for about one-third of all human deaths, this difference effectively means that – if the final promise is actually honored – each year about six million more people will die from poverty-related causes than would have died had the original promise made in Rome been kept.
