From the book "sharing Nature's Interest" by Nicky Chambers, Craig Simmons and Mathis Wackernagel we show you table 4.1. where you can see how the size of earth's population affects the remaining size for all. Pleace notice that the share of planet earth is calculated to be 1.6 ha with a population of 6 billion which is slightly larger then the current size of over 5 billion people.
In the calculations there is discriminated between two situations: the first where biodiversity is guaranteed maximally at 25% and the second, where 12% of planet earth is reserved for wild animals and plants.
