When the water is discussed, usually will be touched upon how to use most of rains by using dams.
Dams can be a fine tool, however, does dam be a real Notre Dame to save the natural gift of waters? Or Dams only support vaporing of water in the long term, when the underground dam can be a good alternative to use natural filter of Earth?
Or, dam is to destruct environment and local communities?
Or, dam can be a haven or new heavens for Malaria mosquitos?
Things are not simple indeed.
And no answer in the end of discussions, except pessimistic sigh?!
