In 'Collapse', author Jared Diamond investigates why some great civilizations throughout history have failed while others succeeded. He explores famous societies like the Vikings of Greenland, the Maya of Central America, and the people of Easter Island, examining the choices they made about their environment. The book argues that a society's fate often depends on how it handles challenges like climate change, deforestation, and relationships with neighbors. By comparing past collapses to modern issues like climate change and resource management, Diamond asks us to learn from history to build a better future.
