Study Notes
Environmental WorldView
- Anthropocentric focuses on the environment for human well-being and economic interests
- Biocentric values all living beings equally, emphasizing the intrinsic worth of all species
- Ecocentric highlights the interdependence of living organisms and ecosystems, and promotes the stability of ecological systems
Traditional Ecological Knowledge (TEK)
- TEK is cumulative local knowledge essential for survival
- TEK emphasizes interconnectedness and sustainability
Understanding Environmental Sciences
- Ecology studies organism relationships to each other and their environment
- Atmospheric science analyzes weather, climate, and global change
- Biology studies living organisms in various specialized fields
- Chemistry identifies substances, interactions, and changes in matter
- Physics studies matter and energy
Oceanography, Geology, and Human Geography
- Oceanography studies the physical and biological properties of the sea
- Geology analyzes the Earth's physical structure, its history, and the processes acting on it
- Human geography examines human activity's impact on Earth's surface
Environmental Science vs. Environmental Studies
- Environmental science uses scientific principles to study and solve environmental problems
- Environmental studies is interdisciplinary, examining environmental issues from social, economic, political, and cultural perspectives
Industrial Revolution Impacts
- Environmental degradation, natural resource depletion, water/air pollution, and urban overcrowding
Green Revolution Impacts
- Deforestation, land degradation, biodiversity loss, and increased greenhouse gas emissions
Three Pillars of Sustainability
- Environmental: preserving natural resources and ecosystems
- Economic: ensuring long-term resource availability through sustainable practices
- Social Justice: fair and equitable treatment of all people, ensuring access to resources
Human Activities and Technologies Affecting Air Quality
- Activities: transportation, industrial processes, agriculture, and household activities
- Technologies: energy production, consumer electronics, and waste management
Structure and Function of the Ozone Layer
- Location: stratosphere, 10-30 km above Earth's surface
- Composition: ozone (O₃) molecules
- Function: absorbs UV radiation, regulates temperature, supports ecosystems, and preserves natural cycles
Effects of Air Pollution on Human Health
- Respiratory diseases, heart attacks, strokes, lung cancer, and premature deaths
Effects of Air Pollution on the Environment
- Acid rain, global warming, smog formation, soil degradation, and wildlife health issues
Climate vs. Weather
- Climate: long-term weather patterns over decades
- Weather: short-term atmospheric conditions
Aquatic Ecosystem Health
- Chemical indicators: pH, dissolved oxygen, nutrients, temperature, and turbidity
Water Supply Impacts
- Water supply provision by public utilities
- Stormwater runoff from impervious surfaces
- Habitat protection, management, and conservation efforts
- Water rights: legal frameworks governing water use and management
Environmental Challenges
- Eutrophication: excess nutrients in lakes leading to dead zones
- Hypoxia
- Loss of biodiversity
- Harmful algal blooms
- Economic impacts on fisheries and tourism
Impacts of Irrigation
- Soil salinization due to improper irrigation practices
- Land degradation
- Reduced agricultural productivity
Water Quality and Availability
- Overextraction problems
- Groundwater contamination
- Water demand increases
- Water availability for agriculture, households, and industries
Point Source vs. Non-Point Source Pollution
- Point source pollution comes from identifiable sources (factories, sewage)
- Non-point source pollution arises from diffuse sources (runoff, agriculture)
Key Processes in Soil Formation
- Physical weathering (mechanical forces like temperature and wind)
- Chemical weathering (reactions with water, oxygen, acids)
- Biological weathering (plant roots, bacteria, fungi)
Soil Properties
- Color (mineral content and drainage)
- Texture (proportion of sand, silt, and clay)
- Soil structure (arrangement of soil particles)
- Soil fertility and nutrient content
Soil Degradation and Mitigation
- Wind and water erosion, salinity, and desertification
- Mitigation strategies include erosion control, soil fertility management, reforestation/afforestation, and improved irrigation techniques
Parts of a Plant
- Roots (anchoring, nutrient/water absorption), stem (support, transport), leaves (photosynthesis), flowers (reproduction), fruits (seed protection and dispersal), and seeds (embryo and nutrients)
Parts of a Flower
- Stamen (male reproductive part), pistil (female reproductive part)
Plant Life Cycle
- Stages: seed stage, germination, seedling stage, vegetative growth, flowering, pollination, fertilization, fruit/seed development, seed dispersals, dormancy, and regrowth
Different Types of Agriculture
- Industrial agriculture (high production, but often harmful)
- Traditional agriculture (soil health emphasis, local economies)
- Subsistence agriculture (local food security)
- Organic farming (pesticides minimized, soil health)
- Urban agriculture (resource efficient)
- Community-supported agriculture (CSA) (direct connections between consumers and farmers)
