Frequently Asked Question
Environment & ClimateRewilding and opportunity cost
Last reviewed: April 12, 2026
Summary
Reduced demand for grazing and feed crops can free land, creating opportunities for rewilding, restoration, and carbon sequestration. The magnitude depends on policy and economics, but the biophysical potential is large.

Evidence Summary
- Opportunity-cost analyses quantify potential food and land gains. Evidence quality: High Limitations / nuance: Land doesn’t rewild automatically; it requires incentives and governance. Bottom line: Land-sparing is one of the strongest arguments for plant-forward diets.
