Important Questions on Water Too Little to Waste
Read the following paragraph and answer the following question:
“I am Mary. There are six persons in my family. My grandfather says water is precious so don't waste it. My mother collects water in a bucket after cleaning rice, dal and vegetables in the kitchen which contains peels of vegetables, and we use this water for our cattle. We do not throw solid food remains, tea leaves and oily wastes down the drain. My father made a channel so that the kitchen and bathroom water flows to the coconut and banana plants in our garden. We always use mild soaps and detergents so that this water may not harm our plants. One day my grandmother asked me to measure drops of water that leaked from a tap in the bathroom, I noticed that three mugs full of water leaked from that tap in a day. Then she asked me to calculate how many mugs of water were wasted in a year. We immediately got our tap repaired.”
