Final answer:
Africa's geography has pros and cons. Pros include diverse environments supporting settled human communities and conditions for agriculture. Cons include arid or infertile land and barriers to movement and exchange.
Step-by-step explanation:
Africa's geography has both pros and cons. Some of the pros include its diverse environments, which range from deserts to rainforests, and have historically supported settled human communities. Well-watered regions, such as the grassy plains of the savannas, have provided conditions for agriculture and the growth of populations. However, there are also cons to Africa's geography. Some areas have arid or infertile land, making agriculture difficult. Additionally, regions like the Sahara desert have acted as barriers to movement and exchange between different parts of Africa.
