Dead Sea

The Dead Sea, bordering Jordan and Israel, is one of Earth's most extreme ecosystems. As the lowest point on land (430m below sea level), its hypersaline water—almost 10 times saltier than the ocean—prevents most lifeforms, earning its "dead" name. Yet hardy microbes and minerals like magnesium thrive here. Famous for its buoyant waters and therapeutic mud, the sea is shrinking rapidly due to water diversion. This unique salt lake, surrounded by stark desert cliffs, remains a natural wonder and a stark reminder of environmental fragility.
