The best scientific estimates tell us human civilization is in overshoot. Were you aware of this? Do you know what overshoot is? Earth Overshoot Day in 2020 is August 22.
Computer modeling by a team of MIT scientists in 1972 estimated the scale of human activity on the planet would cause systems to fail within a hundred years. Such failure is expected when humanity’s footprint on the planet consistently exceeds its carrying capacity. Since 1972, study after study, and report after report, has warned we are in overshoot – the sum total of human activity is too much for the Earth’s ecosystems to bear.
Since 2003, scientists at Global Footprint Network have been analyzing UN data and satellite imagery to estimate the planet’s capacity to meet our needs (biocapacity), and humankind’s footprint - or demand (ecological footprint) - on that capacity. Their analysis suggests we have been in overshoot since about 1970. Welcome to Overshoot explores overshoot’s causes, effects, and possible solutions, as well as some of the barriers to solving the problem.
