What factors have caused changes in human population growth rates during the pas

Human growth rates have been growing exponentially for the past 100,000 years due to several different factors. Of all the factors that have caused the changes in human population growth rates, all of them fall under the umbrella of adaptation. Since the pre-agricultural period, humans have been adapting to their surroundings and passing these adaptations along to their succeeding generations. With the introduction of the agricultural period came an increase in human population growth as well due to domestication of plants and animals and the development of farming. Behind innovations in technology and more food available, the time it took the human population to double dipped to under 1,000 years. The industrial period brought an even more rapid pace to the human growth rate. Attributions of new technologies powered by fossil fuels caused food production to increase, and medical advancements allowed people to stay healthier.
