Namibia faces a number of challenges providing health care to its citizens. The country has a dual system of public (serving 85% of the population) and private (15%) health care providers. In the financial year 2006/07, Government and private health expenditure combined accounted for 8.3% of the country's Gross Domestic Product.
A river is a large body of water that flows over land in a long channel. Most rivers begin high in the mountains or hills. A river's source may be a melting snowfield or glacier (although in Namibia we generally rule these 2 options out!), a spring, or an overflowing lake. As a river flows in its channel, it receives more water from streams and other rivers, and from rainfall. At the end of a river is its mouth, where the water empties into a larger river, a lake, or an ocean.
At 824,292 km2 (318,261 sq mi),Namibia is the world's thirty-fourth largest country (after Venezuela). After Mongolia, Namibia is the least densely populated country in the world (2.7 inhabitants per square kilometre (7.0/sq mi)).
