An excerpt from "Shake Hands with the Devil" by Lieutenant-General Roméo Dallaire

"If the entire population of the planet is represented by one hundred people, fifty-seven live in Asia, twenty-one in Europe, fourteen in North and South America, and eight in Africa. The numbers of Asians and Africans are increasing every year while the number of Europeans and North Americans is decreasing. Fifty percent of the wealth of the world is in the hands of six people, all of whom are American. Seventy people are unable to read or write. Fifty suffer from malnutrition due to insufficient nutrition. Thirty-five do not have access to safe drinking water. Eighty live in sub-standard housing. Only one has a university or college education. Most of the population of the globe live in substantially different circumstances than those we in the First World take for granted."
