Study Notes
Conservation vs. Preservation
- Conservation emphasizes responsible use of natural resources, viewing the environment as a resource for human benefit.
- Preservation focuses on protecting the environment from harmful human activities, valuing it intrinsically.
Historical Stages of Environmental Thought
-
Stage 1 (1800s): Pragmatic Conservation
- Advocates for conservation based on the utilitarian value of resources.
- Gifford Pinchot stated, "The first principle of conservation is development and use of natural resources for the benefit of people."
-
Stage 2 (1900s): Biocentric Preservation
- Nature is valued for its own sake, regardless of usefulness to humans.
- Emphasizes that other organisms have a fundamental right to exist.
- Land Ethic principle: Responsibility to care for the land morally.
-
Stage 3: Modern Environmentalism
- Emerged from pollution issues post-World War II; incorporates science and diverse expertise to tackle environmental challenges.
-
Stage 4: Social Justice and Environmentalism
- Links environmental quality with social progress and equity.
- Advocates for global action and increased involvement of developing nations in environmental leadership.
Sustainable Development
- Defined as development that meets present needs without compromising future generations' ability to meet their needs.
Systems Thinking
- Involves recognizing phenomena as interconnected components, promoting an understanding of the bigger picture.
Common Features of Ecosystems
- Energy flows one-way through ecosystems, with material cycling being essential.
- Ecosystems consist of living organisms interacting with their abiotic environment.
Ecosystem Energy Flow
- Energy is converted into biomass through photosynthesis and consumed across trophic levels.
Biogeochemical Cycles
- Matter conservation principle states that matter cannot be created or destroyed in a closed system like Earth.
- Earth functions as a closed system concerning matter exchanges.
Fundamental Life Building Blocks
- SPONCH represents six essential elements: Sulfur, Phosphorus, Oxygen, Nitrogen, Carbon, and Hydrogen.
Human Impacts on Ecosystems
- Deforestation leads to declines in the biosphere, causing issues like flooding due to disrupted water cycles.
- Dams create barriers that affect natural water flow.
Ecosystem Interactions
- Ecosystem dynamics change continually due to interactions among organisms.
- Competitive exclusion principle states that no two species can occupy identical niches for extended periods; one will adapt or become extinct.
Importance of Biodiversity
- Ensures system redundancy, allowing ecosystem services to persist despite species changes.
- Complex ecosystems contain diverse interactions, niches, and species, fostering resilience.
Key Concepts
- Resource Partitioning: Similar species dividing resources to coexist.
- CoEvolution: Mutual influence on species' evolution through their interactions.
- Symbiosis: Long-term interactions among species, can be beneficial or detrimental.
