Potential Carrying Capacity of the Human Population

WithShunji Murai

Most of the development in the twentieth century, particularly after world war II, has accelerated a crisis toward famine and even extinction of human civilization, which could result from an extreme diminution of natural resources. Immigration into big cities has been a critical factor in the 20th century because overdevelopment and rapid industrialization cause high consumption of energy and pollution. The population will increase as the carrying capacity goes up and even after it starts to decrease. Birth and death rate may be almost the same at an equilibrium, with a higher proposition of aged people. There should be a limit for increase in human population with a constraint on crop production. An increase of carrying capacity should be more moderate, which would allow a gentle curve of population increase and finally an equilibrium.
