Overpopulation. however. is not a problem for developing countries only. Rapid population growth in already overcrowded and underdeveloped areas of the world has given rise to an unprecedented pressure to migrate. as people seek decent. and more hopeful lives for themselves and their families. According to a report by the United Nations Population Fund [UNFPA]. over 100 million people. or nearly 2 percent of the worlds population. are already international migrants. and countless others are refugees within their own countries. Many of the worlds industrialized nations are now straining to absorb huge numbers of people. and in the future. as shortages of jobs and living space in urban areas. and resources such as water. agricultural land. and new places to dispose of waste grow even more acute. there will be even greater pressure to emigrate. Population growth is an enormous problem. but one we can solve--if we make a determined effort to do so. Over the last three decades. population programs have been remarkably successful.
