The Caspian Sea: The World's Largest Lake Spanning Five Countries

The Caspian Sea: The World's Largest Lake Spanning Five Countries
The Caspian Sea, despite its name, is actually the world's largest lake by surface area. It is bordered by five countries: Kazakhstan, Russia, Turkmenistan, Iran, and Azerbaijan. The Caspian Sea covers an area of about 143,000 square miles and has a maximum depth of 3,363 feet. It is a unique body of water, being both saline and endorheic, meaning it has no natural outlets to the ocean.

Why is the Caspian Sea Called a Lake?
The Caspian Sea is often referred to as a lake because it is an endorheic basin, meaning it doesn't drain into any ocean or sea. It is also saline but not as salty as an ocean, which makes it unique among the world's large bodies of water. These characteristics set it apart from other seas and make it more akin to a lake from a geological and hydrological perspective.

Natural Resources and Geopolitical Importance
The sea is rich in natural resources, including vast reserves of oil and natural gas, making it a geopolitical hotspot. Fishing is another significant industry, with sturgeon and its prized caviar being the most notable catch.

Environmental Challenges
However, the sea faces environmental challenges such as pollution from industrial activities and overfishing, which have led to declining fish stocks. Conservation efforts are in place, often involving collaboration among the bordering countries, to protect its unique ecosystem and natural resources.

Tourism and Activities
The sea is also a popular tourist destination, offering activities like boating, fishing, and bird-watching.
