Africa evokes images in people's minds. To some it brings to mind pictures of colourfully attired tribes, grassy ‘veldt’ plains dotted with wildlife, rivers and sunsets. For others, it means mines and minerals and diamonds while for still others it evokes images of disease, poverty and starvation. Extending over 8,000 km from Cape Agulhas (South Africa) in the South to Cape Angela (Tunisia) in the north is the continent of Africa with 54 countries. It is the second-largest continent with 30.4 Million square kilometres, over 1.2 Billion people and a mind-boggling linguistic, ethnic and cultural diversity. Along with Arabic, English, French and Portuguese, there are nearly 2,000 native languages spoken in Africa with Arabic being the most widely spoken language! It also surprises many that two-thirds of Africa lies in the Northern Hemisphere, though in popular perception Africa is in the southern hemisphere. Africa also straddles not only the equator but also the prime meridian making it the only continent situated in all four cardinal hemispheres.
