Known as “The Gathering Place”, friendly Oahu is the center of the Hawaiian universe. It boasts all the allure of the Islands with the buzz of busy Honolulu and slow paced Island life on Northern and Eastern shores. The most visited Hawaiian Island; Oahu welcomes 4.5 million travelers each year. Surprisingly, many of its star attractions are in serious danger. A shocking amount of Oahu’s coastline has been eroded because of rising sea levels. Studies found 24% of Oahu’s beaches have narrowed significantly or disappeared altogether.

7. The Dead Sea

The Dead Sea is one of the saltiest bodies of water in the world. Some say its mineral rich waters relieve conditions from psoriasis to arthritis. For the past 40 years, countries bordering the Dead Sea have been siphoning huge amounts of water from the River Jordan, the seas primary water source. This has caused the water level to drop 80 feet! Shrinking the Dead Sea by a third already, scientists believe it could dry up in as little as 50 years.
