Africa covers approximately 20.3% of Earth's total land area, making it the second-largest continent after Asia (29.5%). The figure of 6% is a significant underestimate.
Africa's vastness encompasses 54 countries, 8 major biomes (Sahara, Sahel, savanna, rainforest, montane, Mediterranean, coastal, marine), the Nile/Congo/Niger basins, and immense mineral, hydrocarbon, and renewable energy potential. Its land area exceeds the US, China, India, and Europe combined.
