The industrial revolution created such a burst of population. So much more than the transition to agriculture. During the 20th century alone, population has increased from about 1.6 billion to over 6 billion by the year 2000. I just can't believe we haven't heard more on the topic of our carrying capacity as a species.
Are we waiting to run out of jobs to find out that our economy can't sustain this many individuals? It seems that way with the increase in outsourcing that has occurred in the last few decades.
Do we feel like we can maintain such a staggering population growth with technological advancements, while fighting against medical technology advances and the earth's limited resources?
This linked video is called Mouse Utopia, where John Calhoun conducted an experiment to observe individual behavior of mice and then rats when they are exposed to unlimited population growth. I don't want to expose much of the video, but the experiment clearly noted a term coined by Calhoun, "behavioral sink", which described the aberrant behaviors in overcrowded population density situations. Everything has its limits.
