we can harvest rainwater in dams and when it is in use we can use it when we brush we can close tap when brushing teeth we should not waste water and in these days there is very very much water pollutin so we have to stop throwing garbage in water we can pick up garbage from water and throw the garbage in the dustbin and than the water will also clean so we have to save water because water is limited when water will end then there is no life in earth but we can purify water but that is very very costly so when anybody throw garbage tell then this story and say dont pollute water then give them a flower and if everybody listen that and do that so 0percent of water will pollute and that is very very good and also good for earth
