    • 17.3A: The Human Population
      This page discusses the Rate of Natural Increase (r), derived from the difference between birth and death rates, highlighting its influence on global population trends, particularly the impact of declining death rates. It examines demographic transitions across countries like Sri Lanka, and the effects of the U.S. baby boom. Despite a low Total Fertility Rate, baby boomers are affecting population dynamics, contributing to concerns about sustainability as projections suggest a rise to 9.
    • 17.3B: Principles of Population Growth
      This page examines how population growth is affected by density-independent factors like natural disasters and density-dependent factors such as competition and resource availability. It describes the importance of breeding territories, the predator-prey dynamics, the effects of parasitism, and the concept of carrying capacity influencing population stabilization.
