Is it possible to stop river water going waste to sea? Would there be any harm to us, to the sea animals, plants near the river-sea junction if fresh water is not allowed to reach the sea? would benefit humans if every drop of fresh water is utilised by us?. kindly educate me on this topic. but some doubt remains in my mind: the pathogenic microbes in fresh water and sewage are killed probably entirely by the salt water of the sea.regards
