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

Explanation

The four 'R's that can save environment are :
1) Reduce 2) Reuse 3) Recycle and 4) Recover
1) Reduce : That is useless if you can afford to save water, by repairing leaky taps and avoiding a shower or switching off unnecessary lights and fans.
2) Reuse : Things that you often tend to throw away, like paper that would save plants and wrapping papers that would minimise pollution.
3) Recycle : May not always be a very good option but useful to conserve certain minerals. In Japan for example, car manufactures recycle many raw materials used in making automobiles. In United states, nearly one-third of the iron produced comes from recycled automobiles.
4) Recover : When we cut trees to construct industries or roads for transportation, it is important to grow trees in another areas.
