The existence of the Dead Sea is seriously threatened by desiccation. Many studies have been carried out in this regard but most of them are not well documented. This paper reviewed and discussed the previous studies and focused on the natural and the political causes of the desiccation during the past periods. It discussed also the different proposed projects regarding the Red-Dead Sea Canal as a solution for the desiccation problem. All the historical, political and environmental implications of the projects have been presented. It was concluded that this solution would harm the Palestinian and Arab interests.
