Borlaug helped feed millions

Vogt warned of limits
Mann describes Vogt, who argued that humans were exceeding Earth's carrying capacity.
He called for conservation and reduced consumption. His warnings inspired the modern environmental movement. Limits matter, he said.
- IDEA 4 OF 8
Food challenges both views
Mann discusses how to feed a growing population.
Wizards favour better crops and technology, while prophets favour sustainable farming. Both sides have strong arguments about feeding billions of people. Both matter.
- IDEA 5 OF 8
Water is a growing problem
Mann discusses the challenge of providing clean water.
Wizards suggest desalination and engineering, while prophets suggest conservation. Scarcity will grow in many regions, so choices made now really matter. Both have merit.
- IDEA 6 OF 8
Energy needs choices
Mann discusses debates over energy, from nuclear power to renewable sources.
Each vision offers different solutions. Debates over power and pollution reflect the same deep divide. Trade-offs are unavoidable in every choice.

Wizards hope for technological fixes, while prophets call for lifestyle changes. The stakes are global and long-term. Time is running short for both approaches.
