The four R's that are used to clean and protect the environment are 

REUSE ,, REFUSE,,RECYCLE AND REDUCE
REUSING is a way through which we can pollute less environment and can help by contributing in SWACHH BHARAT to make india clean, hygienic , and healthy .... reusing plastic bottles,, jars,,tins etc is very useful as reusing old materials rather than making new ones and throwing them here and there
