Write about the four 'R's that can save environment.

Explanation

By pursuing the maximum of four R's i.e., Reduce, Reuse, Recycle and Recover, we can save the environment in an effective way.
Reduce : It means to use less, I would save electricity by switching off unnecessary lights and fans, prefer walking or cycling than using a vehicle, turn off the engine of car at red light, repair leaky taps and would not waste food.
2) Recycle : It means to collect used things like plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesising or extracting fresh plastic, paper, glass or metal.
3) Reuse : It refers to use things again and again. For example instead of throwing away used envelops, they can be used by pasting new labels.
4) Recover : We should implement 'recover' to prevent environmental threat. For example when we cut trees to construct industries or roads for transportation, it is important to grow trees in another areas.
