Tree of Life
It may not be the biggest, tallest or oldest tree in the world, but it's certainly the loneliest — and the thirstiest. Growing alone in Bahrain’s barren desert, miles from another tree or visible water supply, this 400-year-old mesquite tree is a miracle of survival. In fact, locals believe the Tree of Life grows on the site where the Garden of Eden once flourished. Its key to success may be a tap root that reaches 115 feet down to an underground aquifer. After vandals began carving names in the trunk and worshippers burned parts of the tree in a religious ceremony, the government took action in 2013, building a recessed concrete wall around this treasure to preserve it for future visitors.
