Population-Consumption v4

Sustainable Goal Simulation

This page illustrates how humanity might achieve the goal of a sustainable state, defined as one with constant population and a total footprint of 0.85 Earth/year, which leaves 15% of ecological resources available for other species. It is based on a simulation using observations described on Simulation p.2, with a direct trajectory from our state in 2013.

The following graph shows how population changes with total footprint. It also includes how happy environments change with total footprint.

Roll over the image to see the trajectory in LogFPH space: LOG(F/h) vs. LOG(Ppop/h). In that graph, the available worlds are shown at the target position, and it assumes that other species will grow back to their population sizes as we reduce our consumption.

The following graph shows how variables change over time, historically through 2013, and projections afterwards.

Roll over the image to see how economic variables change. Recall that Size is proportional to Gross World Product.
