Option 2: Remove, Reclaim, Restore
Option 3: Recover, Resupply, Refill
Option 4: Replace, Refurbish, Repurpose
Correct Answer: Reduce, Recycle, Reuse
Solution : The correct answer is (A) Reduce, Recycle, Reuse
The "3 R's" in waste management stand for reduce, recycle, and reuse. These principles are aimed at minimizing waste generation, promoting the efficient use of resources, and reducing the environmental impact of waste.
Reduce: This involves minimizing waste generation by using resources wisely, avoiding unnecessary consumption, and adopting sustainable practices. It focuses on preventing waste at its source.
Recycle: Recycling involves collecting and processing waste materials to transform them into new products. It aims to recover valuable resources from waste and reduce the need for extracting and processing raw materials. Reuse: Reusing means finding alternative uses for products or materials to extend their lifespan. It involves using items multiple times or repurposing them for different functions to minimize waste.
By following the principles of reduce, recycle, and reuse, individuals and communities can contribute to more sustainable waste management practices and help conserve resources and reduce environmental pollution.
