Instant Genius Feeding the world’s growing population
Dec 2, 2024
Vaclav Smil, a multidisciplinary researcher, dives into the pressing issue of feeding over 8 billion people. He explores how our evolutionary history shapes staple foods and our survival chances. Smil discusses the biological and technological hurdles in food production and warns about the limitations of modern farming methods like organic practices and hydroponics. He emphasizes the urgent need for sustainable agriculture and why technology still struggles to provide viable long-term solutions for global food security.

Episode notes
Photosynthesis Sets Hard Limits
- Photosynthesis limits food production because it's intrinsically inefficient and we can only tweak conditions, not its core efficiency.
- Rising population demand clashes with these natural limits, creating a fundamental tension.
Population Drove Farming's Rise
- Human population growth forced the switch from hunter-gathering to settled farming to sustain larger numbers.
- Intensive agriculture enabled civilizations and makes large modern populations possible.
Few Plants Feed Most People
- Humans chose a small set of high-yield, digestible plants through long evolutionary trial and error.
- Losing those core staples (rice, wheat, maize, potatoes) would threaten large-scale food security.
