An extra child born today in the United States, would, down the generations, produce an eventual carbon footprint seven times that of an extra child in China, 55 times that of an Indian child or 86 times that of a Nigerian child.
The 2003 World Values Survey found that the happiest people in the world live in Nigeria, where almost 70% of interviewees described themselves as 'very happy'.

The underprivileged tend to adjust their desires to their means. They forsake the exclusive desires of people who live in rich countries so as not to be disappointed.
