below and on your knowledge of social studies.
… Europe’s waterways were also a blessing. Its
rivers flowed gently into sheltered, navigable
bays. The Rhine is a wide, slow-moving river that
can be used as a highway for goods and people.
The Mediterranean is calm, almost a lake, with
many big ports. Compare this to Africa. Despite
being the second-largest continent, Africa has the
shortest coastline, much of which is too shallow to
build major ports. Most of its big rivers—fastmoving, dramatic, vertiginous [dizzying]—are not
navigable. Add to that the tropical heat and
propensity [tendency] for disease and food
spoilage, and you have a compelling geographic
explanation for African underdevelopment—
surely not the only factor, but a significant
one.…
