In fact, groundwater veins are decreasing. To get clean water, the well must dig deeper into the ground, some tens of meters deep and still hopeless. The flow of rivers is also decreasing. In Vietnam in the past few years, the Red River, Duong River ... often fell into the state of "shallow river", the water level dropped below the alarming level, making ships unable to circulate ...
