The Jordan River is of extremely high cultural, political, economic and environmental importance - not only for the Middle East. Important world heritage sites can be found on its shores and the Jordan itself is holy for Christians, Jews and Muslims. Each year, hundreds of thousands of pilgrims symbolically get baptized in the river, even though the water in the Lower Jordan River represents a public health hazard. The diversion of over 96% of its fresh water for industrial use, domestic consumption and agricultural irrigation has done untold damage to the river. Once a powerful stream, the Lower Jordan River is nowadays only a trickle of untreated sewage and salt water. By now, half of its biodiversity is destroyed and the otter as well as the 500 million migratory birds, which roost in the Jordan River Valley twice a year, are endangered.
