This text continues the Hudson Institute's analytical tradition of exploring the future through the lens of social science and history. Featuring the independent work of Hudson researchers (and those associated with the institute), the book starts with an overview of the possible contours of the world in the 21st century by exploring the likely and unlikely changes in the areas of population, such as war and peace, urban development and space exploration. The authors present a 21st century that will see the successes and tremendous growth found in the United States and the industrialized world spread throughout the globe, benefiting workers and developing countries in ways previously thought impossible. The book also identifies several potential threats for future growth and possible solutions to prevent such scenarios.
