    Study Notes

    Deontological Ethics

    • Dolphins have intrinsic value and should be protected regardless of their usefulness to humans.
    • All life forms have inherent value.
    • The government has a responsibility to ensure safe, healthy, productive, and aesthetically pleasing surroundings for all Americans.

    Utilitarian Ethics

    • The purpose of conservation is to maximize happiness for the greatest number of people over the longest period.
    • The government should aim for the widest range of beneficial environmental uses without causing harm to health, safety, or the environment.
    • Failing to address climate change will lead to greater harm than the immediate benefits of inaction.
    • The "Tradedy of the Commons" describes the depletion of a shared resource due to individual self-interest without consideration of the negative impact on others.

    Policy Process

    • Identifying which problems to address.
    • Evaluating policies.
    • Implementing policies.
    • Crafting policies.
    • Approving policies.

    Ethical Positions

    • Anthropocentrism: only human beings matter, animals exist solely as a resource for people.
    • Anthropocentrism: only considers how actions affecting the environment will impact people.
    • Ecocentrism: considers all living and nonliving components of an ecosystem.
    • Biocentrism: all life, both living and non-living, has value, and all species deserve protection.

    Efficiency Gains

    • The Jevons Paradox states that efficiency gains in the use of a resource can lead to increased consumption of that resource.

    Government Policies

    • Clean Water Act: policy governing water pollution.
    • Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA): prioritizes hazardous waste sites for cleanup.
    • Wilderness Act: establishes the highest level of environmental protection for federal lands.
    • Resource Conservation and Recovery Act: governing the disposal of solid and hazardous waste.
    • National Environmental Policy Act: requires an Environmental Impact Statement for federal actions affecting the environment.

    Ecosystem Services

    • Some examples listed include wetlands filtering water and trees shading rivers to keep water cool.

    Environmental Concerns and Protection

    • Wilderness Act, defining areas where humans are visitors to prevent environmental damage, and maintain the natural state.
    • Defining and recognizing Ecocentrism where all aspects of ecosystems are valuable.

    Urbanization

    • Factors that contribute to suburban sprawl include the Federal-Aid Highway Act of 1956, lack of regional planning, and consumer culture.
    • Green infrastructure can help improve the heating and cooling efficiency of buildings and retain stormwater. This includes rooftop gardens and ground-level rain gardens.
