A new study from the University of Oxford suggests that shifting towards more plant-based diets could create up to 56 million new jobs globally and reduce labor costs by nearly $1 trillion by 2030. The research, published in The Lancet Planetary Health, shows that as demand for animal-based foods decreases, the agricultural workforce in livestock-heavy economies could decrease by as much as 28 percent, with new jobs opening up in fruits, vegetables, legumes, and nuts production.

The study emphasizes the importance of a "just transition" for workers and communities as dietary changes impact livelihoods. Governments and industries will need to invest in retraining programs, redeployment support, and horticultural development to ensure a fair transition for agricultural workers. While moving towards plant-based diets could have environmental benefits, such as reducing greenhouse gas emissions and freeing up land for reforestation, it will also require careful planning and support to manage the shift in labor from animal farming to fruit and vegetable harvesting.
