Study Notes

Learning Objective 1.1: Tragedy of the Commons

The tragedy of the commons occurs when individuals prioritize self-interest, depleting shared resources and harming the entire group.
Real-life examples include: overfishing, deforestation, water pollution, traffic congestion, and overgrazing.
Solutions include: regulations, privatization, community management (using Elinor Ostrom's principles), and incentives.

Learning Objective: Braiding Sweetgrass

A wider ecological consciousness can be fostered through acknowledging and celebrating our reciprocal relationship with nature.
Reciprocity: Mutual exchange between humans and nature, with balanced giving and taking.
Gratitude: Appreciating nature's gifts, acknowledging natural resources as gifts.
Native knowledge: Indigenous wisdom emphasizing respect, connection, and sustainability (e.g., Three Sisters planting).
Human impact: Negative consequences of human actions on the environment (i.e. pollution and destruction).

Learning Objective 1.2: Ecosystem Services

Ecosystem services are the benefits humans derive from natural processes sustaining life.
Regulating services: Processes regulating environmental conditions (e.g., wetlands filtering water).
Provisioning services: Products obtained from ecosystems (e.g., food, water, timber).
Cultural services: Non-material benefits like recreation and spirituality (e.g., ecotourism, spiritual sites).
Supporting services: Services necessary for all other services (e.g., photosynthesis, nutrient cycling).

Learning Objective 1.3: Carbon Cycle

Carbon cycles through various fluxes (photosynthesis, respiration, decomposition, combustion, consumption) and reservoirs (atmosphere, biosphere, lithosphere, oceans).
Photosynthesis removes CO₂ and respiration releases it, creating a balance.
Human impacts: Burning fossil fuels, deforestation, and industrial processes increase atmospheric CO₂.
Short-term carbon cycle: Carbon moves through living organisms and the atmosphere.
Long-term carbon cycle: Carbon is stored in fossil fuels, rocks, and sediments for millions of years.

Learning Objective 1.4: Solid Waste Disposal

Landfills: Have liner systems preventing leachate contamination.
Methane Creation: Decomposition of organic waste releases methane (a potent greenhouse gas).
Incineration: Reduces waste volume but releases toxic emissions.
Waste Reduction: Increasing composting, mandatory recycling programs, and public awareness can reduce solid waste.

Learning Objective 1.5: Ocean Acidification

Mitigation involves reducing emissions (like using renewable energy).
Adaptation involves adjusting to impacts (like altering aquaculture practices).

Learning Objective 1.6: Nitrogen and Phosphorus Cycles

Nitrogen Cycle: Nitrogen fixation, ammonification, nitrification, assimilation, and denitrification are crucial.
Nitrogen Importance: Essential for proteins and DNA. Nitrogen gas (N₂) is unusable. Usable nitrogen compounds are produced by nitrogen-fixing bacteria.
Haber-Bosch Process: Increases food production but contributes to greenhouse gases and pollution.
Dead Zones: Excess nutrients lead to algae blooms, oxygen depletion harming aquatic life. Associated with human impacts on the nitrogen cycle.

Learning Objective 2.1: Anthropocene

Evidence for the Anthropocene includes geological layers, biodiversity changes, atmospheric changes, and human impacts.
Suggested start dates include:
- Agricultural Revolution (~10,000 years ago): Large-scale agriculture impacted environments.
- Industrial Revolution (~1750-1800 CE): Fossil fuel burning increased atmospheric carbon dioxide.
- Great Acceleration (~1950 CE): Post-WWII period marked by increased industrialization and population growth.

Learning Objective 2.2: Plate Boundaries and Climate History

Climate change involves long-term shifts in global climate patterns, influenced by natural (e.g., volcanic eruptions, orbital changes) and human (e.g., greenhouse gasses) factors.
Milankovitch Cycles: Eccentricity (orbit shape), axial tilt, and precession affect solar radiation and climate.
Plate tectonics: Continental drift alters ocean currents, volcanic activity, and carbon emissions, influencing long-term climate changes.
Positive Feedback: Initial warming releases greenhouse gases, trapping more heat, causing further warming.

Learning Objective 2.3: Paleoclimate Data

Incoming solar radiation, reflected radiation (albedo), trapped radiation, and greenhouse gases are components to consider.

Learning Objective 2.4: Climate Change Consequences

Mitigation: Actions to reduce greenhouse gas emissions (e.g., using renewable energy).
Adaptation: Adjusting to the impacts of climate change (e.g., building sea walls).

Learning Objective 3.1: Biodiversity

Biodiversity is the variety of life on Earth, including genetic, species, and ecosystem diversity.
HIPPO (habitat loss, invasive species, pollution, population growth, and overexploitation) are key threats to biodiversity.
Solutions include habitat restoration, sustainable resource use, and pollution reduction.

Learning Objective 3.2: Ecosystem Disturbance

Trophic Levels: The energy transfer in a simple food chain (producers, primary consumers, secondary consumers, tertiary consumers).
Rule of 10: Only 10% of energy is transferred to the next trophic level.
Trophic Cascades: Removing a predator disrupts energy flow, leading to unchecked prey populations.

Learning Objective 3.3: Food Webs and Species Interactions

Bioaccumulation: Accumulation of pollutants within an organism.
Biomagnification: Increased pollutant concentration across trophic levels. The concentration is higher in apex predators.
