The benefits of animal-free diets are manifold. The savings in healthcare is just one of them. "Springmann and his team imagined several potential dietary scenarios in 2050, comparing healthcare and climate-related costs if the world keeps up its current meat-heavy diet, versus shifting to a diet that meets standard global dietary guidelines. For many regions of the world, this shift would mean drastically cutting meat consumption and eating more fruits and vegetables. Springmann also calculated the hypothetical costs of a world of vegetarians (a diet with no meat), and vegans (no eggs, dairy, or animal products whatsoever)."
