Is the Red-Dead Sea Conveyance project the only option to restore the Dead Sea?

The Dead Sea has been shrinking for the last 40 years by as much as 1m (3.3ft) a year. The Jordanian and Israeli governments along with the Palestinian Authority have designed and approved a project to transfer water from the Red Sea to the Dead Sea in order to restore the Dead Sea to its old status. However, this project poses various environmental threats. So is there no other way to stop the Dead Sea from "dying"?
