    Study Notes

    Chapter 4: Human Population Growth

    • Human population growth has been slow for most of history, limited by resources, disease, and high mortality.
    • The agricultural and industrial revolutions led to a significant increase in population growth, transitioning from lag growth to exponential growth.
    • The 20th century saw explosive population growth, driven by advancements in medicine, sanitation, and agriculture.
    • The current global population growth rate raises concerns about resource depletion and potential ecological consequences.
    • Carrying capacity, the maximum population size an environment can sustain, is unknown for humans.
    • Age distribution significantly impacts population growth.
    • Different countries exhibit varying age structures due to factors like fertility rates, healthcare, life expectancy, economic development, and migration patterns.
    • Rapid growth countries often rely on more resources. No growth (Japan, Germany) have few young people to maintain society.
    • Slow growth countries (US, Cayman) have more stable demographics.
    • Social factors, like child marriage, son preference, limited access to birth control, and delayed marriage, influence population growth rates in different countries. AIDs, high disease rates can impact reproductive age group, and have profound consequences.
    • Lag Growth: A delay between declining death rates and birth rates, leading to rapid population growth.
    • Exponential Growth: Constantly increasing growth rate.
    • J-curve: Graph of exponential growth, showing rapid population increase.
    • Biotic Potential: Maximum reproductive capacity under ideal conditions.
    • Carrying Capacity: Maximum population size an environment can support.
    • Environmental Resistance: Factors limiting population growth.
    • Density-Dependent Limiting Factors: Factors impacting growth based on population density.
    • Density-Independent Limiting Factors: Factors impacting growth regardless of density.
    • Birth Rate: Number of births per 1,000 individuals.
    • Population Density: Number of individuals per unit area.
    • Sex Ratio: Proportion of males to females.

    Chapter 5/6: Land Use, Deforestation, and Environmental Ethics

    • Intact forests provide crucial ecosystem services, including carbon sequestration, biodiversity support, soil protection, water regulation, and aesthetic value.
    • Non-food plants in Cayman include West Indian Mahogany (medicinal uses), sage, Aloe vera, soursop, and Spanish needle (medicinal uses).
    • Deforestation in Africa is primarily driven by small-scale agriculture (slash and burn) and infrastructure development.
    • South American agriculture faces issues like large-scale agricultural expansion, infrastructure development, urbanization, and the environmental degradation associated with slash-and-burn agriculture.
    • Asian agricultural issues include palm oil plantations, traditional slash-and-burn farming, infrastructure development, hydropower projects, and urbanization.
