The case for economic growth is compelling, especially for those countries who have a relatively low
standard of living. Growth makes the scarcity problem less acute. Related to this issue, growth also makes
it possible for nations to alleviate poverty. There are also nonmaterial considerations that result from
economic growth such as the ability to increase one’s leisure time. Proponents of growth argue that growth
and environmental protection can occur simultaneously and that the case for limiting growth in order to
