Until about 13,000 years ago, Europe and North America were home to
a menagerie of massive mammals. Mammoths, camels, and lions walked
the ground that has become our cities and 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
wolves back to Scotland, and elephants to America's Great Plains as
stand-ins for their extinct native brethren. By reintroducing big
browsers and carnivores to colder climes, 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 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.
