We could feed all 8 billion people through a nuclear winter. Dr David Denkenberger is working to make it practical

Abstract

The article explores the possibility of feeding the entire world in the case of a global catastrophe, such as a nuclear winter or an asteroid impact. While acknowledging the potential for widespread devastation and disruption of agricultural infrastructure, the author contends that sufficient food could still be produced using alternative food sources. The article examines a range of potential options for feeding humanity in such a scenario, including cultivating mushrooms on decaying wood, growing bacteria on natural gas, harvesting seaweed, and relocating plants to more favorable environments. The author analyzes the relative advantages and disadvantages of each of these options, as well as their feasibility and potential for scaling up in a timely manner. Finally, the author explores the broader implications of these findings for global catastrophic risk reduction, arguing that a comprehensive plan for alternative food production could help to prevent a collapse of civilization and promote global cooperation in the face of disaster. – AI-generated abstract.
