The little-known history of how the Sahara was transformed from a
green and fertile land into the largest hot desert in the world The
Sahara is the largest hot desert in the world, equal in size to
China or the United States. Yet, this arid expanse was once a
verdant, pleasant land, fed by rivers and lakes. The Sahara
sustained abundant plant and animal life, such as Nile perch,
turtles, crocodiles, and hippos, and attracted prehistoric hunters
and herders. What transformed this land of lakes into a sea of
sands? When the Sahara Was Green describes the remarkable history
of Earth’s greatest desert—including why its climate changed,
the impact this had on human populations, and how scientists
uncovered the evidence for these extraordinary events. From the
Sahara’s origins as savanna woodland and grassland to its current
arid incarnation, Martin Williams takes us on a vivid journey
through time. He describes how the desert’s ancient rocks were
first fashioned, how dinosaurs roamed freely across the land, and
how it was later covered in tall trees. Along the way, Williams
addresses many questions: Why was the Sahara previously much
wetter, and will it be so again? Did humans contribute to its
desertification? What was the impact of extreme climatic
episodes—such as prolonged droughts—upon the Sahara’s
geology, ecology, and inhabitants? Williams also shows how plants,
animals, and humans have adapted to the Sahara and what lessons we
might learn for living in harmony with the harshest, driest
conditions in an ever-changing global environment. A valuable look
at how an iconic region has changed over millions of years, When
the Sahara Was Green reveals the desert’s surprising past to
reflect on its present, as well as its possible future.
