Define the 4R principle in brief.

The 4R ‘s are Reduce,Reuse,Recycle and Recover.
Reduce: The harmful element among our daily routines have to be removed.Example: We should use paper bag instead of Polythene.
Reuse: We can use plastic to make many hand craft.
Recycle:We should make new things from the old things.
Recover: After gone through all the above process if any left over is there then we should recover it.
