A meta-analysis of studies on the maximum sustainable human population on earth found the median estimate to be 7.7 billion people¹. Earth's current human population is about 7.5 billion and is forecasted to exceed 7.7 billion in 2020². Population limits are heavily influenced by lifestyle and resource usage. How would a globally widespread plant-based diet influence the population limit for humans on earth?
