Africa is the second largest continent, covering about a fifth of the world's landmass. It stretches equally to the north and south of the equator and is made up of many different kinds of landscapes and ecosystems.
Africa consists of over 50 states, many of which became independent in the 20th century. The whole continent was ruled by European powers until the world wars. Today, many nations still suffer from the lack of democratic elements. Dictators and military leaders rule politically unstable countries, in which there are no free elections.
The continent has great deposits of the world's most valuable minerals and raw materials, including diamonds, coal, copper and gold. However, Africa is the least developed of all continents. Food is often scarce and droughts hit many regions on a regular basis. Diseases spread throughout Africa, life expectancy is low and poverty is widespread.
