Study Notes
Finiteness of Resources
- Earth is the only known habitable planet in our solar system
- Our time, experiences, achievements are limited to this one planet
- We need to conserve Earth's resources responsibly.
Understanding the Impact of Resource Depletion
- Minerals: depletion will have social, economic, and environmental impacts.
- Fossil Fuels (Oil): depletion will have social, economic, and environmental impacts.
- Forests: depletion will have social, economic, and environmental impacts.
Mining
- Mining is the process of extracting minerals from the Earth's surface, including land and sea.
- Minerals have distinct chemical and physical properties that are important in product manufacturing.
- Mineral deposits require sufficient extent and concentration for extraction.
Philippine Mineral Deposits
- The Philippines is rich in mineral resources (metallic and non-metallic).
- Copper, nickel, limestone, marble, and gold are significant resources.
- The Philippines has notable chromite deposits.
- The Marcopper mining disaster in 1996 highlights the environmental consequences of improper mining. (Example of an environmental consequence)
Impacts of Mining (Benefits & Costs)
- Benefits: Employment, additional revenue
- Costs: loss of cultural value, loss of profitable share, loss of revenue once depleted, loss of biodiversity, animal migration
Fossil Fuel Depletion
- Fossil fuel depletion is the decline of fossil fuels in a specific area.
- Geologist M. King Hubbert predicted peak oil in 1956.
- Transitioning from readily available, low-cost oil to unconventional, higher-cost extraction.
- Fossil fuel depletion will impact transportation, energy sources, and cost.
Deforestation
- Forests are vital ecosystems with high biodiversity.
- Deforestation rates were high in the 1980s, peaking at 150,000 hectares per year.
- Causes of deforestation include shifting cultivation, land use conversion, forest fires, illegal logging, and fuelwood harvesting.
- The National Greening Program aims to plant one million hectares of trees by 2016.
Impacts of Deforestation (Benefits & Costs)
- Benefits: Employment, revenues
- Costs: loss of cultural value, loss of safety net for diseases, displacement of people, loss of biodiversity
Overfishing
- Millions depend on fishing for food and income.
- Overfishing threatens aquatic resources, depleting fish populations, and disrupting marine ecosystems.
- Philippines has immense marine resources but faces the challenge of unsustainable fishing practices.
- Overfishing impacts fish stocks, fishing communities, and the environment.
Poverty, Hunger, and Food Security
- Resource depletion contributes to rising poverty and hunger by making food and resources less available.
- Overpopulation, inadequate resources, and lack of access to services are key factors influencing food security.
Assessments (Individual/Group Work)
- Lifestyle choices affect consumption of resources.
- Relationship of ecosystem services to forest resources.
- Emerging technologies to replace fossil fuels.
- Short-term vs. long-term impacts of fossil fuel depletion.
- Adapting to fossil fuel depletion (transportation, food, energy).
- Creating a one-minute video to present solutions
