Answer:
Let us read a story about a village
where there are less garbage and more wisdom. Nanu studies in Class VI. He is very fond of making paper planes. His mother is very annoyed when he tears off sheets from new notebooks to make aeroplanes, but Nanu does not care. Once Nanu went to his aunt’s village, along with his mother. He was amazed at the variety of things his cousin Shyam had made. Files from old charts, greeting cards decorated with flowers made from pencil shavings, mats from old clothes, baskets from used old polythene bags were some of the items Nanu liked. Shyam had even made a diary from invitation cards! One morning Nanu went looking for his grandmother (Nani). He saw that she was applying a thick paste on a basket. Nanu asked, “Nani, What are you doing? What is this paste?” “This is paper-mâchè, a paste made of clay and paper in which I have also mixed some rice husk”, replied Nani. “But, why are you putting it on the basket?”, asked Nanu. “To make it stronger”, said Nani and added, “would you like to learn this from me?” Nanu was not very keen and ran outside to play. He was only interested in tearing up papers to make planes. In fact, he also started tearing up papers from Shyam’s files! Shyam collected all the pieces of paper Nanu had used, wondering what to do about him! He just did not listen to anyone! It was Nanu’s birthday in a few days. Shyam planned to invite Nanu’s friends. Nanu took out the money from his mud pot and went to the market. He bought some paper hats for his friends. He asked the shopkeeper for a polythene bag to keep the hats, who gave him a paper bag instead of polythene. Nanu also bought many other items like biscuits and toffees. He found it difficult to carry all of these things as no shopkeeper was ready to give a polythene bag. Shyam had told him to carry a cloth bag with him and he was sorry he did not listen to him. Somehow, he managed to reach home with all his purchases (Fig. 16.8). Nanu’s friends enjoyed the feast on his birthday and played many games. All his friends wore the shiny paper hats Nanu had bought! Shyam had made beautiful papiermâchè masks for Nanu’s friends. He had a special gift for Nanu as well. A photo frame and a greeting card made from the paste of all the pieces of paper Nanu had thrown away! It was a new experience for Nanu. All his friends went home with their masks. Nanu was too excited to finish his meal and look at his gifts. Nanu returned home after his holidays were over. How different his town was from Shyam’s village! There were no rag pickers in the village as it was neat and clean.
