LECTURE 11POPULATION ECOLOGY


Factors contributed to this staggering increase
FACTORS CONTRIBUTED TO THIS STAGGERING INCREASE….

  • Human steadily developed the capacity to expand into new habitats and new climate zones.

  • Humans increased the carrying capacity in their existing habitats.

    • (management of food supplies through agriculture increased the carrying capacity for the human population).

  • Human populations sidestepped limiting factors.

    • (better sewage systems, controlling disease agents; tapping existing forms of energy; major factors were sidestepped)
