Observe the picture and answer the following question: What could be done to keep rivers clean? Discuss.

It is very important to keep the rivers clean as they are the source of fresh water. To keep rivers clean the people living near the bank of the river should follow certain measures. They are as follows- They should never dump and litter the wastes like plastic, garbage, etc., into rivers. They should not bathe their animals and wash their clothes and utensils in the river. They should not throw the sewage waste and industrial waste into the rivers. Set up water treatment plants to remove all toxic chemicals before letting the wastewater into the rivers. Following these measures can stop the water pollution, spread the of water-borne diseases and save the lives of many aquatic organisms living in the water.

Observe the image and answer the following question: If you wanted to drink some water, from which part of the river would you like to drink? Why?

The River is the main source of freshwater. I would like to drink water from the starting point where the river begins before it reaches the village and towns. The water is clean and pure in the beginning, and it gets polluted as it reaches the village. Further, it gets contaminated due to the release of industrial wastes near towns and cities. Drinking such dirty water near the village, cities and towns leads to water-borne diseases affecting our health.
