This document discusses several topics related to human population dynamics and conservation biology. It begins with introductions to mathematics of population growth, determinants and demographics, world population growth through history, and population growth and the environment. Specific impacts of overconsumption, emissions, pollution, and urbanization are outlined. Consequences of demographic change are then examined, including dependency ratios and demographic dividends. The document also covers demographic convergence, factors influencing human population change, population growth models, and impacts of population growth such as on land use and resource distribution. Key terms related to isolated populations, density-dependent and independent limitations, and conservation biology are defined.
