Study Notes
Sustainable Resource Use
- The tragedy of the commons describes a situation where individuals prioritize their own self-interest, overusing shared resources which leads to environmental degradation and resource depletion.
-
Specific Examples
- Overfishing: Global fish populations are often over-exploited, impacting marine ecosystems.
- Deforestation: The Amazon rainforest faces deforestation due to loggers and farmers seeking short-term profits, ignoring long-term biodiversity and climate implications.
- Groundwater Depletion: Shared aquifers are often overused for agriculture/urban water needs, causing water scarcity and land subsidence.
- Environmental Impacts: Loss of biodiversity as species struggle to survive in depleted ecosystems.
Impacts of Commercial Fishing and Aquaculture
- Overfishing: Depletes fish populations, leading to biodiversity loss and socioeconomic repercussions.
-
Examples:
- Cod Fishery Collapse: The Atlantic cod population drastically decreased due to overfishing, impacting North American fishing industries and marine biodiversity.
- Bluefin Tuna: High demand in sushi markets has led to a dramatic decline in bluefin tuna stocks, prompting international fishing restrictions and conservation efforts.
- Environmental Impacts: Loss of species impacts entire aquatic ecosystems and bycatch (unintended capture of species). Fishing methods like trawling, gillnets, and dredging negatively affect communities and individuals dependent on fishing.
- Possible Solutions: Implementing sustainable fishing practices like catch limits, seasonal bans, and selective fishing gears.
Impacts of Aquaculture
- Aquaculture is a potential sustainable fish production method but has risks.
- Rapid expansion due to efficiency, low space requirements, and minimal fuel consumption.
-
Examples:
- Salmon Farms: Farmed salmon operations in Norway and British Columbia are major suppliers but face challenges like disease and pollution.
- Shrimp Farming: Coastal shrimp farms in Southeast Asia contribute to seafood production but have caused mangrove deforestation and habitat loss.
- Environmental Impacts: Contaminated wastewater, escaped farmed fish disrupting wild populations, high fish density leading to outbreaks of disease in fish.
- Possible Solutions: Improved waste management, integrated multi-trophic aquaculture (IMTA) combining species in a single system.
Impacts of Clearcutting
- Clearcutting, while advantageous for timber production, has significant environmental impacts.
- While offering immediate financial gains, it has ecological downsides.
-
Ecological Downside:
- Leads to soil erosion as roots holding the soil are removed.
- Increases soil/stream temperatures from loss of canopy cover.
- Disrupts natural water drainage, leading to flooding.
- Burning trees releases stored carbon dioxide (CO2) which contributes to the greenhouse effect.
Sustainable Forestry
- Sustainable forestry practices help preserve forest ecosystems and combat deforestation.
-
Examples:
- Reforestation by planting trees in deforested areas.
- Ecologically sustainable forestry techniques that ensure minimal impact, such as selective logging.
- Recycling wood products.
- IPM (Integrated Pest Management) using biological, cultural, and chemical methods to control pest populations.
- Addressing diseased trees promptly.
- Using prescribed and controlled burns.
Impacts of Mining
- Depletion of Accessible Ores: As easily accessible ores are mined out, companies utilize lower-grade ores requiring more resources to extract.
-
Examples:
- Gold mining shifts to low-grade ores.
- Copper mining extracts lower-grade deposits, increasing waste.
- Environmental Impacts: Increased energy use, higher greenhouse gas emissions, soil and water pollution from mining waste.
- Possible Solutions: Improved recycling methods to recover metals, efficient extraction technologies to minimize waste.
Impacts of Mining (cont.)
-
Mining Wastes: Surface mining (strip mining) removes large volumes of soil and rock to access ore deposits.
- Examples: Strip mining for coal in the Appalachian region removes large areas of vegetation and soil.
-
Open-pit Mining: Open-pit mining for copper exposes large tracts of land, altering ecosystems.
- Environmental Impacts: Habitat destruction, loss of biodiversity, increased erosion/sedimentation in waterways.
-
Subsurface Mining: As surface coal resources dwindle, mining companies transition to subsurface mining, which is more capital-intensive.
- Examples: Transition from surface mining to subsurface mining for metals.
- Environmental Impacts: Increased subsidence risk (ground caving), increased energy use, more carbon emissions.
- Possible Solutions: Encouraging sustainable mining practices, implementing stricter regulations, promoting alternative energy and circular economy policies.
Impacts of Urbanization
-
Urban Sprawl: A shift from densely populated areas to low-density suburban development, often encroaching on rural lands.
- Examples: Cities expanding into agricultural/natural areas, leading to habitat loss and fragmentation.
- Environmental Impacts: Increased reliance on automobiles, resulting in higher carbon emissions and pollution; loss of biodiversity and farmland; conversion of land.
- Possible Solutions: Smart growth initiatives to encourage denser urban development, zoning regulations, and public transportation networks.
-
Impact on the Carbon Cycle: Urbanization contributes to rising atmospheric carbon dioxide levels from fossil fuel combustion and waste.
- Examples: Transportation, heating, electricity, and landfills rely on fossil fuels releasing greenhouse gases.
- Environmental Impacts: Enhanced greenhouse effect, climate change, air pollution affecting human and ecosystem health.
- Possible Solutions: Promoting renewable energy sources, waste reduction and recycling, incentivizing public transport.
Depletion of Resources and Saltwater Intrusion
-
Water depletion due to Saltwater Intrusion: Rapid population growth and over-extraction of groundwater strain freshwater resources, leading to saltwater intrusion, especially in coastal areas.
- Environmental Impacts: Decreased freshwater availability for ecosystems and communities, potential harm to drinking water supplies and agriculture.
- Possible Solutions: Implementing water conservation measures, watershed management, and water quality enhancement policies. Desalination can also provide alternative water sources.
Impervious Surfaces and Flooding
-
Impervious Surfaces: Prevent water from infiltrating the soil, contributing to urban flooding and disrupting natural water cycles.
- Examples: Parking lots, roads, and rooftops preventing rainwater absorption.
- Environmental Impacts: Increased runoff, soil erosion, water pollution, and flooding during heavy precipitation events; reduced aquifer recharge.
- Possible Solutions: Implementing green infrastructure (e.g., green roofs, rain gardens), promoting permeable pavements, adopting urban forestry and transportation policies, minimizing impervious surface creation in urban planning.
