Russia is home to some of the world's longest and most significant rivers, including the Volga, Lena, and Ob. These rivers play a crucial role in the country's ecosystem, economy, and transportation, providing vital resources and routes for trade and travel. The Volga, often referred to as the national river of Russia, flows through central Russia and is the longest river in Europe. The Lena and Ob are also essential, draining vast areas of Siberia and supporting diverse wildlife and communities along their banks.
