We all need a healthy envirnment, but we prduce waste every day, and it is harmful t ur envirnment. Repeat these three wrds daily: reduce, reuse and recycle.
Reduce means “use less”. D nt waste things. It saves mney and causes less pllutin. D nt rder mre fd than yu can finish. Turn ff the lights when yu d nt need them. Befre yu buy smething new, think whether it is really necessary because maybe the ld ne is just as gd!
Reuse means “use again”. Use things fr as lng as pssible. Lk after them s that they will last. Repair them if pssible. D nt thrw them away and buy new nes. D nt use paper cups r paper bags. It is better t use china cups and clth bags because they can be used many times.
Recycle means “change things int smething else t be reused”. Althugh it takes energy t change things int smething else, it is better than thrwing things away r burning them.
