(c) This is a story of a village where people are very intelligent and they produce less garbage. Nanu is student of VI class. He loves to make, aeroplanes of paper. He used to tear papers from his books whether new or old. His mother was very worried but Nanu never cared.
Once, Nanu went to his aunt house with his mother. He was surprised to see number of things made by his cousin Shyam. He had made files out of old charts. He had made a congratulation card by pasting flowers of pencil sharpenings, mats from old rags, baskets using polythene bags etc. Shyam has also made a diary of invitation cards.
One day, Nanu saw his grandmother, putting a thick paste over a basket. He asked, “Grand ma ! What are you doing ? What is this paste ?”. “It is a paper paste, I have prepared it using clay and paper and some husk.” Grandmother replied. Nanu asked, ” Why are you putting paste on the basket ?” Grandmother replied, “To make it hard and durable. Do you want to learn it ?”.
Nanu had no interest in it. He ran outside for playing. He only had interest of making aeroplanes. He started tearing papers from Shyam’s files also. Shyam collected all the papers thrown by Nanu. He wanted to punish Nanu.
After few days, Nanu birthday came. Shyam planned to invite Nanu’s friends. Nanu broke open his coin box and went to market, He bought some papers hats for his friends. He asked the shopkeeper to put them in a polythene bag but the latter put them in a paper bag. Nanu bought other things like biscuits and toffees, but no shopkeeper was ready to give him polythene bag. It was difficult to him to carry those things. He was repenting now as Shyam had suggested him to take cloth bag with him but he had not lent an ear to his advice.
Nanu’s friends enjoyed the party. They also wore the bright hats bought by Nanu. Shyam had made face masks from paper paste for Nanu’s friends. He also made a photoframe and congratulation card. It was also made from the paper thrown by Nanu. It created a new excitement in Nanu’s mind. He was excited and wanted to see his gifts also.
Q. 6. Do you think it is better to use compost instead of chemical fertilisers ? Why ?
Ans. The use of compost is far much better than chemical fertilizers. One the fertilizers are expensive and secondly they pollute our environment and soil. On the other hand, compost is cheap and it does not pollute environment and soil. It enriches the soil fertility. Therefore, we must use compost instead of a fertilizer.
