Question

In the context of conservation of natural resources, explain the terms reduce, recycle and reuse. From among the materials that we use in daily life, identify two materials for each category.

Answer 1

Reduce means to use a material/commodity in lesser quantity,
e.g electricity and water
Recycle means a material that is used once is collected and sent back to a manufacturer so that they can make some other useful material from it:
e.g., plastic cups and buckets, glass tumbler, paper, metal objects
Reuse means using a thing over and over again instead of throwing it away. It does not involve the process of recycling either in small or large scale:

 e.g., used envelopes, plastic carry bags, bottles of jam.
