Kamali's father said that three parts of the Earth is covered with water. We have so much of water on the earth. But her aunt says that there is shortage of water. We should save water. If we waste water the way we do right now, we will have no water to drink one day. Think why?
Most of the water on Earth is salty ocean water which is not fit for drinking. Only a very small amount is fresh water suitable for human use. If we pollute and waste this limited fresh water, we will face severe drinking water shortage in the future.
