The Good and Bad of Globalization

Jeffrey D. Sachs, the director of the Center for Sustainable Development at Columbia University, explores the impact of globalization throughout human history. Sachs asserts that globalization has produced both benefits, such as widespread prosperity and cross-cultural linkages, and negative consequences like slavery, war, and damage to the planet. He identifies globalization as an inseparable aspect of human development, starting with early migrations from Africa. Sachs provides a comprehensive explanation of our interconnected world, reinforcing his argument with praise from Kirkus Reviews, Foreign Affairs, and Ian Goldin, co-author of Age of Discovery.

The Paradox of Globalization

Sachs’ book explores how globalization led to human advancement with complex societies and economies, but also resulted in environmental destruction and intense competition. Over 70,000 years, humans communicated, traveled, and traded across borders. While globalization has allowed people to flourish, humans now face significant challenges on their home planet as a result. The coexistence of cooperation and competition has been a consistent theme in human progress, leading to both prosperity and turmoil.

The History of Globalization

Sachs traces the first wave of globalization to 50,000 to 70,000 years ago and highlights that humans developed egalitarian societies through social finesse, not brutality. Successful hunting led to the extinction of some animal species. Sachs reminds us that harming our surroundings while globalization has always been a part of human history.

The Evolution of Human Culture

Early humans were initially wanderers, but societies that settled in one place were able to thrive and develop art and written language. The growth of agrarian communities further allowed for prosperity, and gradually, people began to create pictograms and hieroglyphics as a means of communicating complex ideas. In this book’s summary, Sachs provides a fascinating account of the evolution of human culture and the significant contributions that settlement, agriculture, and communication have made to our world today.

The Horse’s Historical Significance

From the Paleolithic age to the Classical Age, horses were a crucial part of societal development. Jeffrey Sachs highlights how horses were domesticated in Europe and Asia, leading to economic growth and globalization. Horses allowed for faster transportation and communication, which played a significant role in the rise of cities. Sachs notes how civilizations such as the Goths, Huns, and Mongols used horses to conquer and expand their territories. The horse’s impact on society during the Equestrian Age was immense and far-reaching.

The Rise and Development of Societies

Sachs’ book highlights the emergence and evolution of societies in Persia, Greece, Rome, India, and China from 1000 BCE to 1500 CE. The written language facilitated knowledge sharing, leading to philosophical developments in Plato and Aristotle. Zoroastrianism provided a worldview of good versus evil, while Judaism and Christianity questioned meaning and morals. China’s Han Empire offered significant progress in mathematics, shipbuilding, and seismometers.
