    Study Notes

    Environmental Protection Agency

    • Established to enforce environmental laws and regulations.

    Global Environmentalism

    • Environmental issues are increasingly complex and global.
    • Key environmental indicators include:
      • Biodiversity
      • Food production rates
      • Climate change
      • Human population growth
      • Resource depletion

    The Demographic Divide

    • Countries divided into developed and developing categories based on economic status.
    • Developed countries:
      • Wealthier with advanced infrastructure
      • Higher education and living standards
      • Higher GDP per capita
      • Lower total fertility rates
      • Higher life expectancy
    • Developing countries:
      • Lower GDP per capita
      • Higher total fertility rates
      • Lower life expectancy
      • Often lack strong environmental regulations

    Resource Depletion and Environmental Challenges

    • Villages with shared resources commonly face quicker resource depletion.
    • Modern examples include climate change, air pollution, and overfishing, illustrating the Tragedy of the Commons.

    Progressive Era

    • The U.S. environmental movement began under President Teddy Roosevelt with conservation efforts.
    • National Parks and Wildlife Refuges established to protect land from resource extraction and preserve ecosystems.

    Hetch Hetchy Debate

    • Caused by San Francisco's fire and subsequent water supply issues after an earthquake.
    • Proposal to build a reservoir in Hetch Hetchy valley required federal government approval.

    Environmental Ethics

    • Emergence of two philosophies:
      • Anthropocentrism: Human-centered approach prioritizing human interests, championed by Gifford Pinchot.
      • Ecocentrism: Nature-centered philosophy valuing ecosystems, promoted by John Muir.
    • Construction of the Hetch Hetchy dam began in 1914, still operational today.

    Types of Natural Resources

    • Inexhaustible resources: Cannot be depleted (e.g., sunlight).
    • Renewable resources: Can be replenished but over long periods (e.g., timber).
    • Nonrenewable resources: Depleted faster than they can replenish (e.g., coal, oil).
    • Recyclable nonrenewable resources: Can be reused but cannot be replaced at the rate used (e.g., metals).

    Modern Environmentalism

    • Environmental disasters in the early 20th century raised awareness for broader issues.
    • Introduction of cane toads to Australia led to invasive species problems.
    • Donora, Pennsylvania experienced a severe air pollution incident in 1948.
    • Nuclear bomb testing fallout exposed risks in inhabited areas.

    Environmental Science

    • The study of interactions between humans and the natural environment, including climate, soil, water sources, and living organisms.
    • Requires interdisciplinary approaches to address complex environmental problems.

    Environmental History

    • Human impact on Earth dates back to early civilization, with ancient Sumerians practicing advanced agriculture around 2400 B.C.
    • Irrigation reliance in Mesopotamia led to soil salinity issues, resulting in agricultural decline over centuries.
    • Two key concepts:
      • Law of Unintended Consequences
      • Unsustainability

    The Tragedy of the Commons

    • Garrett Hardin's concept highlights environmental conflict in shared resources.
    • Commons are prone to depletion as individuals prioritize self-interests, leading to overuse and resource exhaustion.
