This reminds me of this report from 2002: https://www.wwf.fr/sites/default/files/doc-2018-10/lpr_living_planet_report_2002.pdf https://www.wwf.fr/sites/default/files/doc-2018-10/lpr_livin... "the world’s ecological footprint will continue to grow between 2000 and 2050 from a level 20 per cent above the Earth’s biological capacity to a level between 80 and 120 percent above it (Figure 30). In these scenarios, 9 billion people in 2050 would require between 1.8 and 2.2 Earth-sized planets in order to sustain their consumption of crops, meat, fish, and wood, and to hold CO2 levels constant in the atmosphere.... Two World3 scenarios were chosen: a standard scenario, which assumes no policy changes over the next 50 years; and an accelerated technology scenario, which assumes significant improvements in resource efficiency. In the standard scenario, the HEF grows and peaks around 2040 at about 150 per cent above the Earth’s biological capacity, while the HWI climbs to around 20 per cent above the 2000 level in 2030 but then falls away rapidly, as the Earth’s productive ecosystems are no longer able to sustain high levels of human consumption. In the accelerated technology scenario the HEF reaches a maximum of 60 per cent above biological capacity in 2020 and then declines back to the 2000 level by 2050, as more resource-efficient technologies reduce the footprint, while the HWI climbs and remains at almost 20 per cent above 2000 levels"
