Recycling is the processing of waste materials to produce new products. Recycling reduces waste and consumption of new wlraw materials, hence reduces pollution. For example, the basic raw material of papaer is the wood from trees. Can you imagine that millions of trees have to be practically cut down to meet the global demand of paper, be it for the printing or manufacturing industries? By recycling paper, we can actually save the trees and increase the supply of oxygen to the loving things on this planet as well as reducing the greenhouse effect. Every piece of paper we recycle is absolutely meaningful and valuable. Recycling not only contributes towards reducing the destruction and pollution of nature but also maintains the Earth for a more secured, safer and comfortable living.
