Until about 13,000 years ago, North America was home to a menagerie
of massive mammals. Mammoths, camels, and lions walked the ground
that has become Wilshire Boulevard in Los Angeles and foraged on
the marsh land now buried beneath Chicago's streets. Then, just as
the first humans reached the Americas, these Ice Age giants
vanished forever. In Once and Future Giants, science writer Sharon
Levy digs through the evidence surrounding Pleistocene large animal
("megafauna") extinction events worldwide, showing that
understanding this history-and our part in it-is crucial for
protecting the elephants, polar bears, and other great creatures at
risk today. These surviving relatives of the Ice Age beasts now
face an intensified replay of that great die-off, as our species
usurps the planet's last wild places while driving a warming trend
more extreme than any in mammalian history. Inspired by a passion
for the lost Pleistocene giants, some scientists advocate bringing
elephants and cheetahs to the Great Plains as stand-ins for their
extinct native brethren. By reintroducing big browsers and
carnivores to North America, they argue, we could rescue some of
the planet's most endangered animals while restoring healthy
prairie ecosystems. Critics, including biologists enmeshed in the
struggle to restore native species like the gray wolf and the
bison, see the proposal as a dangerous distraction from more
realistic and legitimate conservation efforts. Deftly navigating
competing theories and emerging evidence, Once and Future Giants
examines the extent of human influence on megafauna extinctions
past and present, and explores innovative conservation efforts
around the globe. The key to modern-day conservation, Levy
suggests, may lie fossilized right under our feet.
