In a place called Nallamada in Andhra Pradesh, people don’t get clean water to drink. People have got used to drinking dirty water.

In Bazaar Gaon in Maharashtra, there is a big water park. There are many rides in the park and children enjoy a lot. Rohan had gone to the water park with his parents. He was very happy to see so many water fountains and water rides. He just started to enjoy the rides when he heard some commotion sound outside the gate of the park. When he went there he saw some women wanted to take some water from the park because there was absolutely no water in the wells and the tanker also did not come to give water. There was a scarcity of water in their colony and so they wanted water from the park. It is very disheartening to see how we use water in the parks for our selfish reasons and there is scarcity of water in another corner of the city. Life without water comes to a complete halt. We should decide what is important, the park or people’s life.

In the second section of NCERT Solutions for Class 4 EVS Chapter 18 – Too Much Water Too Little Water, is about a village called Holgundi in Karnataka where people were facing scarcity of water. The wells all dried up because of no rain. People were moving out of the village, which was a very big concern for the Panchayat. The Panchayat decided to consult with the children’s panchayat called Bhima Sangha. The elders of the village said that there was a well at the top of the hill but that also dried up. The children went to inspect the well and found that it was filled with stones and mud. There were cracks in the well wall. Children first cleaned the well and repaired the cracks. They planted plants and trees around the well. When the first rain came, the well was filled with water. They also left some fishes in the well. Slowly, over the years that area became green and the well was completely filled. Ever since then the villagers never faced the scarcity of water.
Conclusion
From this lesson, we have learnt that water is very essential for our living. We should have safe and clean drinking water so that we don’t fall sick. We should use water very carefully so that everyone gets water. We should plant more trees for rain to come every year.
