Von Foerster, who was the founder of the Laboratory of Biological Computers at the University of Illinois, developed this theory in 1960. As quoted from Grunge, he calculated that if the population growth of humans continues unchecked, by the year 2026 we will reach the maximum limit that this planet can sustain.

This theory has sparked a lot of debate among scientists. They argue that technological advancements and innovation in food production and resource management can overcome the challenges faced by population growth. Therefore, although it can provide warnings about potential risks in the future, theories like this should not be seen as definite predictions.

On the contrary, the theory should encourage us to think critically about how we can sustainably manage Earth's resources and ensure a decent future for future generations. Heinz von Foerster advises regulating birth rates and suggests that the government should intervene to keep the human population low. He also suggests imposing a tax on families with more than two children.
