In the American west, irrigation is causing a buildup of salts that is killing the soil. When I travel west, the further I go, the saltier the water tastes, and I can't stand to drink it. I have to buy bottled water.http://www.sciencedaily.com/releases/2013/01/130111092529.htm
Jan. 11, 2013 — The salinisation of rivers is a global problem that affects to countries all over the world and it causes a high environmental and economic cost, and poses a high risk to global health. Climate change and the increasing water consumption can worsen even more the future scene, according to an article published on the journal Environmental Pollution based on the research developed by an international team led by the experts of the Department of Ecology of the University of Barcelona Narcís Prat and Miguel Cañedo-Argüelles.
