Thanks for the source. The results look very good, so I would be suspicious… in any case, people should focus on the meat feasible ones because people are not gonna just stop eating meat. Besides meat provides nutrients like B12 that you cannot just find in non-processed plant food.

Around two thirds of the 500 options were declared feasible or “probably feasible” for a world with zero-deforestation.

For the scenarios where the human diet was vegan, 100% of the options were feasible, whilst with the vegetarian diet, the figure was 94%.

However, if the rich western-style diet were to become the global average, only 15% of the scenarios were possible without deforestation.

Despite meat-free diets providing the widest range of feasible options, it could still be possible to have a diet including meat, but factors such as the crop yield and crop land expansion into other non-forested areas became more important.

A combination of the rich diet and low-yielding, organic farming techniques resulted in no feasible scenarios.

Although the model doesn’t consider political and economic factors, the team are positive about the results.
