The correct option is Inventing or procuring alternate sets of eco-friendly technologies..
Explanation
The assertion that "environment and rural development cannot be viewed as distinct subjects" is a foundational principle of Sustainable Development. It emphasizes that economic progress in rural areas must be achieved without compromising ecological balance, necessitating the integration of environmental concerns into developmental planning.
Analysis of Options:
- Industrialization of rural areas at any cost. is incorrect: "Industrialization at any cost" prioritizes development over the environment, treating them as distinct and conflicting interests, which contradicts the assertion.
- Inventing or procuring alternate sets of eco-friendly technologies. is correct: Inventing or procuring alternate sets of eco-friendly technologies allows for rural development (improving livelihoods and productivity) while simultaneously preserving the environment. This approach bridges the gap between the two subjects, ensuring they are viewed as interconnected.
- Reducing the population in rural areas. is incorrect: While population pressure is a factor in environmental degradation, the assertion specifically targets the methodology of development rather than demographic control as the primary solution.
- Stopping all agricultural activities to save the environment. is incorrect: Stopping agricultural activities would halt rural development entirely, failing to address the "development" aspect of the assertion.
Key Takeaway: Sustainable rural development requires the adoption of appropriate, eco-friendly technologies that harmonize economic growth with environmental conservation.
