Episode notes
Culture Shapes Carrying Capacity
- Carrying capacity is usually seen as an environmental limit like food and water.
- Malcolm reframes it as cultural: which culture lives there changes how many people the region can support.
Appalachian Student Claims Overpopulation
- Malcolm recounts a college student from Appalachia claiming their region 'overbred' and exceeded carrying capacity.
- Malcolm challenges that view, arguing people can migrate or use trade and technology to sustain higher populations.
Technology Decouples Population From Land
- Malcolm argues modern trade and technology decouple human carrying capacity from local agricultural limits.
- Importing food, urban agriculture, and energy technologies raise a region's effective capacity dramatically.
