Chapter 1 · Question 5
Explain sustainable development with reference to resources and future generations.
Answer
Direct Answer
Sustainable development means development that meets present needs without harming the ability of future generations to meet their needs. It requires careful use of groundwater, minerals, forests, and other resources so that economic growth does not create long-term scarcity.
Simple Explanation
Sustainable development means using resources today in a way that does not leave less for tomorrow. It means not exhausting groundwater, minerals, and forests faster than they can be replaced or conserved.
Exam-Ready Structure
Sustainable development is defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Core ideas:
• Intergenerational equity: Resources belong to all generations — past, present, and future. It is unfair for one generation to consume resources so fast that later generations face scarcity or environmental collapse.
• Resource management: Many resources are finite and non-renewable:
- Groundwater: In many parts of India, groundwater is being depleted faster than it is recharged. Over-extraction for irrigation and urban use threatens future water availability.
- Minerals and fossil fuels: Iron ore, coal, petroleum, and natural gas take millions of years to form. Once extracted and used, they cannot be replaced. Careful extraction, recycling (metals), and substitution (renewable energy for fossil fuels) are essential.
- Forests and biodiversity: Deforestation for agriculture, mining, and urban expansion destroys habitat and species. Once a forest or species is gone, its value — timber, medicinal plants, climate regulation, cultural importance — is lost forever.
• Environmental impact of growth: Economic growth based on burning fossil fuels has led to climate change, air pollution, and ocean acidification, which harm current and future generations alike.
• Balancing growth and conservation: Sustainable development does not mean stopping development. It means choosing technologies and pathways that use resources efficiently, generate less waste, and rely more on renewable sources.
• Examples of sustainable practices:
- Rainwater harvesting to recharge groundwater.
- Solar and wind energy as alternatives to coal and oil.
- Organic farming and agroforestry.
- Recycling of metals, paper, and plastics.
- Laws and regulations to limit pollution and protect forests.
Sustainable development is thus a guiding principle — reminding us that economic progress should not destroy the natural base on which all life, including human life, depends.
Key Points
- Sustainable development means development that meets present needs without harming the ability of future generations to meet their needs.
- It requires careful use of groundwater, minerals, forests, and other resources so that economic growth does not create long-term scarcity.
