This lecture explores the journey of humankind from the control of fire to the conquest of the globe, tracing the development of hunting, migration patterns, and the impact of big-game hunting on human culture. It delves into the origins of Homo sapiens' estrangement from nature and the adversarial relationship with the environment during Europe's glacial period. The speaker presents a new perspective on the ecological impact of human activities and offers insights into a more sustainable way of life for the future.
