"Findings indicate that there are significant differences across countries of the world in the consumption quality of life of its citizens. Using the Human Development Index, which is composed of longevity, knowledge, and standard of living, data reveal that lives worsen from west to east, with the worst conditions in South Asia and Sub-Saharan Africa. Additionally, environmental damage estimates, as determined by the EDI composite developed specifically for this investigation, demonstrate that wealthier nations create environmental degradation that is consistent with their higher consumption patterns rather than their absolute numbers."[6]
