[...]Moreover, consumption is not an issue for rich countries alone. In developing and transition countries there are well over one billion people with enough income to enjoy an affluent lifestyle. Their aggregate spending in purchasing-power parity (as measured in local terms) already matches that of the United States. Certain effects of their consumerism, such as pollutant emissions from cars, which cause urban smog and global warming, are a salient concern both locally and worldwide. China alone, with 300 million new consumers and possibly twice as many within ten years, could soon exert an environmental impact to rival that of the United States.
