Description
Government officials estimate that dryland salinity resulting from land clearing is now threatening an area of land about half the size of the entire Australian state of Victoria-and in turn, the farming and ranching that is the underpinning of the national economy. In the words of a country song popular in the outback during the mid-1980s: 'Stock won't graze on pastures turned to salt.' Read about salination in Australia in this National Geographic News Eye in the Sky article.
