    Study Notes

    Introduction to Overconsumption

    • IPAD Equation: Environmental impact = population × affluence × technology
    • Biological Basis: Humans evolved to accumulate resources; those who consumed more lived longer and reproduced more.
    • Neurological Basis: Dopamine release during consumption creates a positive feedback loop. Repeated consumption requires stronger stimuli (e.g., "acquiring" another item).
    • Social Competition: Belonging to specific groups can drive consumption to signal status and outdo others.
    • Shifting Needs: Current trends (e.g., social media, advertising) may encourage overconsumption compared to investments in long-term relationships.

    Moving Forward with Consumption

    • Decoupling: Separating economic activity from environmental impact is crucial.
    • Types of Decoupling:
    • No decoupling: Resource use grows at the same rate as economic output.
    • Relative decoupling: Resource use grows more slowly than economic output.
    • Degrowth: Removing economic growth as a goal, focused on resource redistribution and sharing of services.

    Donut Economics

    • Focus: Nine key environmental challenges and living within ecological boundaries.
    • Goal: Sustainable economic growth and addressing environmental issues simultaneously.
    • Production Cycle Transformation: Transition from "take, make, use, lose" to incorporate "regenerate and restore".
    • Distributive Approach: Ensuring equitable access to goods and services.

    Environmental Justice and Racism

    • Environmental Justice Defined: Fair treatment and meaningful involvement of all people regarding environmental laws, regulations, and policies.
    • Historical Context: American environmental justice movement arose from issues like Love Canal and Warren County, highlighting racial disparities in environmental impacts.
    • Key Concepts: Environmental Racism, NIMBY/PIBBY (Not In My Backyard/Place In Black Backyards).
    • US Case Studies: Love Canal, Warren County, Waste Oil Disposals.
    • Canadian Case Studies: Grassy Narrows, Aamjiwnaang First Nation, Village of Blue Water, Africville.

    Ecosystem Energy Flows

    • Energy Flow: Unidirectional flow of energy; matter cycles within ecosystems.
    • Photosynthesis: Phototrophs convert radiant energy to chemical energy.
    • Gross Productivity: Total radiant energy converted to stored chemical energy.
    • Cellular Respiration: Glucose and oxygen produce carbon dioxide, water, and ATP.
    • Net Primary Productivity: Energy available for transfer to the next trophic level.
    • Energy Transfer (TE): Efficiency of energy transfer between levels; generally 10% per trophic level.
    • Assimilation: Proportion of ingested energy assimilated by consumers.
    • Metabolism: Catabolic (energy production) and anabolic (growth) processes; greatly influence energy demands

    Energy Flow in Aquatic Ecosystems

    • Impacts of warmer waters and ocean acidification on fish populations
    • Phenological mismatch: disruption in the timing of ecological cycles
    • Impacts of ocean acidification: increased energy demands for shell organisms and decreased energy for other processes
    • Effects of increased acidity and warmth on the efficiency of energy transfer between trophic levels.

    Energy Flow in the Arctic

    • Changes in sea ice availability impacting polar bears' hunting strategies.
    • Dovekies facing challenges in obtaining plankton due to changing weather patterns
    • Shifts in food sources (plant-based to fungal) due to climate change
    • Effects on keystone species (e.g., arctic lemmings) affecting the entire ecosystem.
