4.5.3 Sustainable Use of Resources

• What is the primary goal of sustainable use of resources?

  Meet current needs without compromise
• Sustainable use of resources is crucial for conserving biodiversity, as it ensures that natural resources are used in a way that preserves balance
• What are the two main classifications of natural resources?

  Renewable and non-renewable
• Match the resource type with its definition and example:

  Renewable resources ↔️ Naturally replenished; solar energy

  Non-renewable resources ↔️ Cannot be replenished; fossil fuels
• Sustainable use ensures resources are available for future generations.
• Why does sustainable use reduce the environmental impact of consumption?

  Maintains ecosystem health
• The importance of sustainable use lies in its ability to balance human needs with the long-term health of the planet
• What is the primary goal of sustainable use?

  Balance human needs with planetary health
• Sustainable use ensures resources are available for future generations
• Sustainable use supports economic stability by preventing resource depletion.
• Match the characteristic with the correct use:

  Harvesting at a rate that allows renewal ↔️ Sustainable use

  Overexploitation of resources ↔️ Non-sustainable use
• What does ecological footprint measure?

  Biologically productive land and water area
• Understanding and reducing ecological footprint is crucial for sustainable resource management
• A small ecological footprint indicates minimal resource depletion and low pollution.
• What is the primary goal of sustainable agriculture?

  Maintain or enhance land productivity
• Match the sustainable practice with its benefit:

  Crop rotation ↔️ Improves soil health, reduces pests

  Integrated Pest Management (IPM) ↔️ Minimizes pesticide use, maintains biodiversity
• Water conservation in sustainable agriculture helps preserve water resources
• Selective logging in sustainable forestry management maintains forest structure and biodiversity.
• What is the impact of clear-cutting in forestry management?

  Habitat destruction and biodiversity loss
• Match the unsustainable practice with its impact:

  Clear-cutting ↔️ Habitat destruction, biodiversity loss

  Lack of soil conservation ↔️ Increased erosion, reduced forest productivity
• Sustainable use of resources meets current needs without compromising future generations
• Overexploitation of resources is a key characteristic of non-sustainable use.
• What are examples of renewable resources?

  Solar energy, forests, water
• The ecological footprint is expressed in global hectares
• What are some key practices in sustainable agriculture?

  Crop rotation, IPM, water conservation
• Match the sustainable practice with its description:

  Crop rotation ↔️ Alternating crops to improve soil health

  Water conservation ↔️ Using water efficiently
• What is the primary goal of sustainable forestry management?

  Preserve biodiversity and productivity
• Sustainable forestry management includes selective logging
• Clear-cutting in forestry can lead to habitat destruction and biodiversity loss.
• What is one negative impact of monoculture plantations in forestry?

  Reduced biodiversity
• Lack of soil conservation in forestry can lead to soil degradation
• What broader concept is related to sustainable forestry management?

  Sustainable use of resources
• Key practices in sustainable water resource management

  1️⃣ Efficient irrigation

  2️⃣ Water recycling

  3️⃣ Rainwater harvesting

  4️⃣ Groundwater protection
• Over-irrigation can lead to water wastage and soil salinization.
• What is one method for collecting and storing rainwater in sustainable water management?

  Rainwater harvesting
• Sustainable energy practices include using renewable energy sources such as solar, wind, and hydro
• Excessive energy consumption increases the environmental footprint.
• What is the goal of sustainable waste management?

  Minimize environmental impact
• Sustainable waste management includes recycling materials into new products
• What is the primary principle of sustainable use of resources?

  Meet current needs without compromising future generations
