4.5.3 Sustainable Use of Resources

• What does the sustainable use of resources aim to achieve?

  Meeting current needs without compromising future generations
• Sustainable use of resources involves maintaining the health and productivity of ecosystems
• Harvesting resources at a rate that allows renewal is a sustainable practice.
• Why is the concept of sustainable use crucial for conserving biodiversity?

  Preserves ecosystem balance
• Match the resource type with its definition and examples:

  Renewable resources ↔️ Can be naturally replenished over a human lifespan; Solar energy, wind power, forests

  Non-renewable resources ↔️ Cannot be replenished or take millions of years; Fossil fuels, minerals
• Sustainable use of resources ensures resources are available for future generations.
• Sustainable use reduces the environmental impact of consumption
• Why is sustainable use important for economic stability?

  Prevents resource depletion
• Focusing on short-term gains is a non-sustainable practice.
• The concept of ecological footprint measures the biologically productive land and water area required to produce resources
• What is the importance of sustainable use?

  Balances human needs with planet health
• Sustainable use ensures resources are available for future generations
• What does ecological footprint measure?

  Biologically productive land and water area
• A small ecological footprint indicates minimal resource depletion and low pollution.
• High meat consumption is a factor that contributes to a large ecological footprint
• What is sustainable agriculture?

  Farming without harming the environment
• Sustainable forestry management aims to preserve biodiversity and productivity
• What is selective logging in sustainable forestry?

  Harvesting mature or diseased trees
• Clear-cutting is a sustainable forestry practice that maintains biodiversity.

  False
• Clear-cutting leads to habitat destruction and biodiversity loss
• What does sustainable use of resources ensure?

  Current needs met without compromising future generations
• Focusing on short-term gains is a characteristic of sustainable use.

  False
• What are the two broad categories of natural resources?

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

  Renewable resources ↔️ Solar energy, forests

  Non-renewable resources ↔️ Fossil fuels, minerals
• Sustainable forestry management involves practices like selective logging
• Clear-cutting is a sustainable forestry practice.

  False
• What is the aim of sustainable forestry management?

  Preserve biodiversity and productivity
• Monoculture plantations in forestry reduce ecosystem resilience
• Match the sustainable forestry practice with its impact:

  Selective logging ↔️ Maintains forest structure

  Soil erosion prevention ↔️ Reduces soil loss

  Replanting ↔️ Ensures forest regeneration
• Sustainable forestry management is related to the broader concept of sustainable use of resources.
• Sustainable water resource management aims to meet current water needs without compromising future generations
• What is one technique used in efficient irrigation to minimize water loss?

  Drip irrigation
• Order the following impacts from sustainable to unsustainable water practices:

  1️⃣ Water conservation

  2️⃣ Water pollution

  3️⃣ Soil salinization

  4️⃣ Depletion of aquifers
• Sustainable water resource management helps conserve biodiversity by maintaining aquatic ecosystems.
• Precision agriculture is an example of a water-efficient irrigation technique
• What is the primary goal of sustainable energy use?

  Meet current needs without harm
• Match the sustainable energy practice with its impact:

  Renewable energy sources ↔️ Reduces carbon emissions

  Improved energy efficiency ↔️ Lowers energy consumption

  Energy storage technologies ↔️ Ensures energy availability
• Sustainable energy use ensures long-term energy security by minimizing environmental impact.
• Sustainable waste management aims to reduce waste at the source
• Order the steps of sustainable waste management from most to least preferred:

  1️⃣ Reduce

  2️⃣ Reuse

  3️⃣ Recycle

  4️⃣ Compost

  5️⃣ Dispose
