There are many needy people across the world who have scarcity of water. we cannot help all but some of them. so we should try to help them. people living in the small houses near my school have to walk too much to fetch water. we can help a little. we can urge municipal corporation to start a fresh water supply to these people. we can even make arrangements to supply water from our schools. or we can tell them other means like digging well or boring. they can also do rain water harvesting and collect atleast a little water.
