This app interactively displays the exact overshoot in the current and future population sizes of all countries under different scenarios. The goal of this app is to warn people of the present and coming danger of overpopulation with recent scientific data. It also presents humane solutions to overpopulation for each country. The sustainable population sizes indicated in this app are the maximum amount of people that could live sustainably in a country for an extended period of time without exploiting other countries. These population sizes are calculated using the ratio between the Ecological Footprint and the Biocapacity of all countries in the world.
