Which of these factors is least likely to explain why the human population has undergone especially rapid growth over the past 200 years? The recent rapid increase in human population is a result of growth even faster than exponential growth. Advances in nutrition, sanitation, and medicine have allowed humans to live at high density without suffering from decreased survivorship and fecundity. Improved medical practices, agricultural production, and economic development have resulted in increases in fertility and infant survival. Human innovations in engineering, technology, and agriculture have enabled the rapid extraction of resources and increases in food production.

One reason that human populations have sidestepped factors that usually control population growth is: a. The carrying capacity for humans has remained constant since humans first evolved. b. Agriculture and industrialization have increased the carrying capacity for our species. c. The population growth rate $(r)$ for the human population has always been small. d. The age structure of human populations has no impact on its population growth. e. Plagues have killed off large numbers of humans at certain times in the past.
Sri K.
Skyrocketing growth of the human population appears to be mainly a result of a. a drop in death rate due to sanitation and health care. b. better nutrition boosting the birth rate. c. the concentration of humans in cities. d. social changes that make it desirable to have more children.
