Sir: Water being the most important ingredient of life helps create and sustain it. There is no doubt that without water we cannot survive for long. This resource is being wasted without any care in the world, particularly in Asia. A recent report claims that clean water worth $ 9 billion is released into the drains in Asian cities. This waste is alarming and a cause for concern for the future of the people living in Asia. SYEDA ZEHRA Karachi
