Would the world economy suffer if everyone went vegan?
Summary
A global shift to plant-based diets would cause significant economic restructuring rather than collapse. Research estimates it could reduce agricultural labor costs while creating tens of millions of new jobs in horticulture and plant-based food industries, though careful transition planning would be needed for affected communities.

Key Points
- 1The study found that adopting plant-based diets could reduce global agricultural labor needs by 5-28%, equivalent to 18-106 million full-time jobs, primarily due to decreased demand for livestock production.
- 2However, the transition would simultaneously create 18-56 million new full-time positions in horticulture.
- 3Countries with large livestock sectors like Denmark and Ireland could see agricultural labor needs drop by 60-61% even with flexitarian diets.
- 4The global plant-based food market is projected to grow from approximately $15.9 billion in 2026 to $49.5 billion by 2036 (Future Market Insights).
Evidence Summary
A comprehensive modeling study by Springmann, Vittis, Obersteiner, and Godfray, published in The Lancet Planetary Health in November 2025, examined how dietary shifts would affect agricultural labor in 179 countries. The net reduction in labor costs was estimated at $290-995 billion per year, representing 0.2-0.6% of global GDP.
The economic impact would vary dramatically by region. Conversely, lower-income nations could see net increases in agricultural employment as they scale up fruit, vegetable, and legume production.
Beyond farming, the plant-based food industry represents a rapidly growing economic opportunity. The broader alternative protein market could reach $150 billion by 2030.
There are also substantial economic benefits from reduced externalized costs. The current food system imposes enormous costs not reflected in food prices — including water pollution, antibiotic resistance, pandemic risk from zoonotic diseases, and climate change — that are ultimately borne by taxpayers and society.
The honest answer is that a rapid, unmanaged transition would indeed cause economic disruption, particularly in livestock-dependent communities.

The Bottom Line
But a gradual, well-planned transition supported by retraining programs and redirection of agricultural subsidies could result in a net economic benefit. History shows that economies regularly undergo structural transformations — from agriculture to manufacturing, from coal to renewable energy — and the key factor is not whether change happens, but how well it is managed.
