Every Drop Counts

A group of students went to a dam for a school picnic. The teacher explained to the students that water is stored in Dams so that we get a steady supply all year. A curious student asked the teacher "Why don't we save rainwater in our city?" The teacher replied "It's because we think we will get water from these dams forever." However, let me tell you that every drop of rain that we can store we should store by rainwater harvesting and now it is very much possible to do it. The student agreed and said "Yes Mam. Every drop counts"
