How Human EXTINCTION Will Occur

In 1950, an American ethologist named John Calhoun created a series of experiments to test the effects of overpopulation on the behavior of social animals. The animals which Calhoun chose for his experiments were mice (and later on rats). He chose rodents as these reproduce rapidly thus allowing him to observe the development of several generations of mice in a relatively short space of time.

Calhoun and his researchers found that in a space-limited/resource-unlimited environment, the population of mice would explode; peak out and then collapse to extinction. This test was replicated several times and found that these led to the same outcome each time. The reason for this phenomenon was found to derive from social decay which worsened with each generation. The social decay led to unrest in the environment, which in turn led to sub-replacement fertility. It was concluded that nature has a limit to social animals' interaction.

John Calhoun’s experiments gained worldwide recognition and his expertise was sought after by government bodies such as NASA. They present a useful yet grim insight into what could be our own future, for no matter how many times Calhoun repeated the experiment, the results led to the same inevitable conclusion: extinction.
