Question

Explain about 3R principle that you have studied.

Answer 1

3R's are important in protecting environment. The first R is reduce and the second R is reuse and the last R is recycle.
Reduce:
We can reduce the waste by using durable goods that last longer instead of things that are used once and thrown away.
e.g: Write on both sides of papers.

• Instead of unnecessary printing, use electronic facilities. Share newspapers, magazines and other things with others

Reuse:
Reusing means using a thing again and again, rather than using and throwing after a single use.
e.g: Instead of using plastic bags, use and throw pens and batteries, use cloth bags, fountain pens and rechargeable batteries.

• Reuse glass bottles for other purposes. Repair foot wears and use them.

Recycle:
The process by which waste materials are used to make new products is called recycling.
e.g: Using old clothes to make paper and melting some plastics to make fl oor mats, plastic boards and hose pipes.
