Water – How to live without it?

Planet’s most valuable natural resource

“The river is a person. It has a name. This name is very old, because even though the river is always young, it’s also too  ancient. It has existed before humans and birds. Since humans have been born , loved and soon spoke, they  named their rivers”.
