Study Notes

Human Population Growth

  • Early humans survived as hunter-gatherers with a low population due to density-dependent growth limiting factors such as competition for food, water availability, predators and disease.
  • Agriculture reduced the impact of food availability and competition as a density-dependent growth limiting factor, leading to an increase in human population.
  • Disease was still present as a limiting factor.

History of Human Population Growth

  • Prior to the industrial revolution, human population grew at a fixed rate of about 0.1% per year.

The Industrial Revolution

  • The Industrial Revolution led to a transition from hand production methods to machines.
  • The use of steam power and factories became more prevalent.
  • Significant medical discoveries were made during this time:
    • The Germ Theory (Louis Pasteur) - the understanding that microbes cause infection
    • Vaccines - injections of dead or weakened viruses that prevent disease
    • Antibiotics - chemical compounds that kill bacteria
    • Water treatment - filtration and addition of chlorine to water for removing microorganisms and toxins

Exponential Population Growth

  • Following the Industrial Revolution, human population growth became exponential, with an increasingly rapid rate and a continuously growing base with a low doubling time.

Human Population Growth

  • Human population growth is increasing exponentially.
  • The population was low due to density-dependent factors such as competition for food, availability of water, predators and disease.
  • People survived by hunting and gathering.
  • Agriculture helped reduce the impact of food availability and competition and the human population began to increase.
  • Prior to the industrial revolution, human population grew at a fixed rate of about 0.1% per year.
  • Human population growth was fixed.

Human Population Growth: The Past and Present

  • Population grew consistently before the industrial revolution.
  • Since the industrial revolution, growth rates have significantly increased.
  • There was a period of exponential growth between 1965 and 2000.
  • The growth curve is J-shaped.
