- Types: Forests, grasslands, deserts, aquatic environments.
- Interactions: Energy flow, nutrient cycling, food webs.
Biodiversity Conservation
- Importance: Maintains ecosystem stability and resilience.
- Types of conservation:
- In situ: Protecting species in their natural habitats.
- Ex situ: Protecting species outside their natural habitats (e.g., zoos, seed banks).
- Threats: Habitat loss, pollution, climate change, invasive species.
Pollution Management
- Types of pollution:
- Air: Emissions from industries, vehicles.
- Water: Contaminants from agriculture, industrial discharges.
- Soil: Pesticides, heavy metals.
- Strategies:
- Prevention (reducing waste).
- Control (treatment technologies).
- Regulation (environmental laws).
Climate Change
- Causes: Greenhouse gas emissions from fossil fuel combustion, deforestation.
- Impacts: Rising temperatures, sea-level rise, extreme weather events.
- Mitigation strategies:
- Reducing emissions.
- Transitioning to renewable energy.
- Enhancing carbon sinks (forests, soil).
Sustainable Practices
- Definition: Methods that meet current needs without compromising future generations.
- Examples:
- Sustainable agriculture (crop rotation, organic farming).
- Water conservation techniques (rainwater harvesting, drip irrigation).
- Waste reduction (recycling, composting).
Soil and Mineral Resources
- Soil: Critical for agriculture, water filtration, and carbon storage.
- Minerals: Essential for construction, electronics, and industrial processes.
- Sustainability: Practices such as crop rotation, conservation tillage, and responsible mining.
Energy Resources
- Types:
- Fossil fuels: Coal, oil, natural gas.
- Renewables: Solar, wind, hydro, geothermal.
- Energy transition: Shift towards renewable sources to reduce carbon footprint.
- Energy efficiency: Using less energy to perform the same task.
Non-conventional Energy Sources
- Definition: Alternative energy sources that are not derived from fossil fuels.
- Examples:
- Solar power (photovoltaic cells).
- Wind energy (turbines).
- Biomass (organic materials).
- Geothermal energy (heat from the Earth).
Introduction to Sustainable Development
- Definition: Development that meets the needs of the present without compromising future generations.
- Goals: Economic growth, social inclusion, environmental protection.
- Frameworks: United Nations Sustainable Development Goals (SDGs).
Overview of Natural Resources
- Definition: Materials or substances occurring in nature that can be exploited for economic gain.
- Types:
- Renewable: Solar, wind, biomass (can be replenished).
- Non-renewable: Fossil fuels, minerals (finite resources).
Biotic Resources
- Definition: Living components that provide ecological and economic benefits.
- Examples: Forests (timber), fisheries (food), wildlife (ecotourism).
- Management: Sustainable harvesting practices, wildlife conservation efforts.
Water Resources
- Importance: Essential for life, agriculture, industry, and energy production.
- Sources: Surface water (rivers, lakes), groundwater, desalination.
- Issues: Water scarcity, pollution, over-extraction.
- Management: Integrated water resource management (IWRM), conservation practices.
Ecosystems
- Definition: A community where living organisms engage with their physical environment.
- Biotic components include organisms such as plants, animals, and microorganisms.
- Abiotic factors encompass elements like water, soil, air, and sunlight.
- Ecosystem types include forests, grasslands, deserts, and aquatic systems.
- Key processes include energy flow, nutrient cycling, and the formation of food webs.
Biodiversity Conservation
- Essential for maintaining the stability and resilience of ecosystems.
- In situ conservation involves protecting species within their natural habitats.
- Ex situ conservation refers to safeguarding species outside their natural environments, such as in zoos or seed banks.
- Major threats to biodiversity include habitat loss, pollution, climate change, and invasive species.
Pollution Management
- Air pollution arises from industrial emissions and vehicle exhaust.
- Water pollution is caused by agricultural runoff and industrial waste.
- Soil pollution results from the use of pesticides and heavy metals.
- Management strategies include waste reduction (prevention), the implementation of treatment technologies (control), and enforcing environmental regulations (regulation).
Climate Change
- Primarily driven by greenhouse gas emissions from burning fossil fuels and deforestation.
- Consequences include increased global temperatures, rising sea levels, and intensified weather patterns.
- Mitigation strategies focus on reducing emissions, transitioning to renewable energy sources, and enhancing carbon sinks such as forests and soil.
