d. them becoming arid desert. The draining of the wetlands is attributed to former leader Saddam Hussein, who reportedly began draining the marshes in 1991 after the Gulf War and subsequent uprisings by people living in the marshes. After draining, little ecological life is able to continue, leaving the areas to dry and die out.
