GREEN SKILLS

Green Skills Introduction

  • Environment's Impact

    • Daily activities affect the environment and vice versa.

    • Urban populations depend on surrounding villages for food and resources.

    • Essential resources include water, fuel wood, litter, etc.

  • Web of Life

    • Living plants and animals form an interconnected ecosystem.

    • School environment is made up of:

      • Physical Environment: Buildings, classrooms, library, labs, and playgrounds.

      • Socio-cultural Environment: Teaching climate, student activities, inclusivity, and respect across diverse backgrounds.

Environmental Pollution

  • Economic Development and Pollution

    • Increase in pollution due to economic advancement.

    • High input agriculture: benefits—more food production; consequences—chemical overuse, soil, and environmental degradation.

  • Sustainable Practices

    • Importance of planning for sustainability. Examples include:

      • Sustainable agriculture

      • Eco-fashion design

      • Manufacturing solar panels

      • Environmentally sustainable home design

Natural Resources

  • Definition

    • Resources: Natural or artificial substances used by humans for welfare.

  • Types and Examples

    • Directly: Water & forests for food, health, and recreation.

    • Indirectly: Forest functions in climate regulation, flood prevention, and nutrient cycling.

    • Natural vs. Artificial Resources

      • Natural: Exist freely and vital for survival (water, land, soils, forests).

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

Types of Natural Resources

  1. Land Resources

    • Used for production, residence, recreation.

    • Finite and subject to various uses.

  2. Forest Resources

    • Self-sustaining communities with vertical structure through trees.

    • Important for wooden products, energy sources, and various natural goods (tannins, gums).

  3. Water Resources

    • Covers 3/4 of Earth's surface, crucial for all life forms.

    • Includes rivers, lakes, and aquifers.

  4. Mineral Resources

    • Naturally concentrated materials in Earth's crust, important for profit.

    • Non-renewable resources: metals and non-metals.

    • Elemental minerals: gold, silver, diamond, and sulfur.

  5. Food Resources

    • Plants for herbivores and omnivores, animals for carnivores and omnivores.

    • Major source of food: agriculture.

  6. Energy Resources

    • Sources that produce heat, power, move objects, or generate electricity.

    • Fundamental sources: solar energy, gravity, nuclear reactions, geothermal energy, stored chemical energy from fossil fuels.

Pollution

  • Definition and Causes

    • Pollution: Derived from Latin 'polluere' meaning to contaminate.

    • Caused by pollutants (solid, liquid, gaseous) from human activity.

    • Example: Factories pollute air and water through harmful emissions and waste.

  • Pollution Types

    • Biodegradable Pollutants: Break down into harmless substances (organic materials, vegetable waste).

    • Non-biodegradable Pollutants: Cannot be decomposed naturally (plastics, industrial chemicals).

Reduce, Reuse, Recycle

  • Concept of Waste Management

    • Reduce: Minimize use and waste generation to lessen pressure on natural resources.

    • Reuse: Find new uses for old items (e.g., turning shirts into pillow covers).

    • Recycle: Reprocess materials for new use, conserving resources and reducing pollution.

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

Examples of 3 Rs

  • Reduce: Minimize usage, such as using both sides of paper.

  • Reuse: Extend the life of items, like donating books.

  • Recycle: Repurpose and process materials, making new products from old paper into papier mache.
