GREEN SKILLS

Introduction to Green Skills

  • The environment influences every aspect of life, and our daily activities also impact it.

  • Urban inhabitants depend on nearby villages for food and rely on forests, rivers, and other ecosystems for resources like water and fuel.

  • Living plants and animals create a web of life upon which humans depend.

  • School environment comprises:

    • Physical Environment: Buildings, classrooms, labs, playgrounds, etc.

    • Socio-Cultural Environment: Teaching methods, student activities, inclusivity, social behaviors, and respect for diversity.

Environmental Pollution

  • Economic development has led to increased environmental pollution.

  • Examples:

    • High-input agriculture uses fertilizers and pesticides to increase food production, leading to soil degradation and ecological harm.

  • The need for sustainable maintenance in environment-friendly practices includes:

    • Sustainable agriculture

    • Eco-fashion design

    • Solar panel manufacturing

    • Environmentally sustainable homes.

Natural Resources

  • Definition: Substances, energy, or organisms benefiting human welfare.

  • Types of natural resources:

    • Direct Use: Resources consumed directly (food from forests).

    • Indirect Use: Resources that contribute to ecosystem functions (climate regulation by forests).

  • Artificial Resources: Human-made resources (biogas, plastics).

Forms of Natural Resources

  1. Land Resources: Used for production, residence, recreation; finite and multipurpose (agricultural, infrastructure).

  2. Forest Resources: Self-sustaining communities providing wood, medicinal products, and energy sources.

  3. Water Resources: Covering 75% of Earth; vital for agriculture, industry, domestic, recreational use.

  4. Mineral Resources: Concentrated materials for profitable extraction (e.g., metals, salts); non-renewable.

  5. Food Resources: Plants for herbivores; agriculture is primary food source.

  6. Energy Resources: Sources of power; includes solar energy, nuclear power, and fossil fuels (non-renewable, environmentally damaging).

Pollution

  • Derived from Latin "polluere" (to soil/defile).

  • Definition: Undesirable changes in the environment impacting health.

  • Types of pollutants:

    • Biodegradable: Decomposable by natural processes (e.g., vegetable waste).

    • Non-Biodegradable: Cannot be decomposed easily (e.g., plastics, chemicals).

  • Sources of pollution include:

    • Industrial discharges affecting air, water, and overall health.

    • Emission of harmful gases from factories.

The Three Rs: Reduce, Reuse, Recycle

  • Reduce: Minimize unnecessary consumption; implications for waste generation.

    • Practical actions: Buy less, avoid plastic bags, use reusable items.

  • Reuse: Repurpose materials for new functions (e.g., old clothing into rags).

  • Recycle: Processing waste into new items; reduces resource depletion and pollution.

    • Recyclable materials: Metals, paper, glass, plastics.

    • Examples:

      • Paper can be recycled into new paper products.

      • Kitchen waste can be composted for organic fertilizer.

  • Proper waste management includes:

    • Segregating wet and dry waste.

    • Safe disposal of non-toxic waste to minimize environmental contamination.
