"A distinguished geologist and a popular science writer Charles Frankel turns his attention in his latest book to the mass extinctions on our planet, considering what the past can tell us about the future. Explaining Earth's past mass extinctions, Frankel suggests that, each time, a decrease in biodiversity created fragile conditions that eventuated into widespread and cataclysmic disappearances. The rise of mammals led to the rise of humans, who, over the past 200,000 years, have become their own geological force, forever affecting the bio-environment, from the massacre of megafauna in the Ice Age to the impoverishment of soils and pollution of waterways and air, to the unwitting transfer of invasive species from one part of the globe to another. After a compelling account of the latest research, Frankel ends with speculations on planetary peril and whether the widespread extinctions, climate change, and loss of biodiversity that we are currently experiencing can be slowed or even reversed. His answer inspires hope and urgency. If humans can redirect and curb some of our basic behaviors (like the obsession to kill and consume other species), we might stand a chance. Still, he eloquently explains that, even if we succeed in this, our way of life and evensome of our ways of being human will be transformed forever. As extinction repeatedly shows those who survive, life is not eternal"--
A compelling answer to an important question: Can past mass extinctions teach us how to avoid future planetary disaster?
On its face, the story of mass extinction on Earth is one of unavoidable disaster. Asteroid smashes into planet; goodbye dinosaurs. Planetwide crises seem to be beyond our ability to affect or evade. Extinctions argues that geological history tells an instructive story, one that offers important signs for us to consider. When the asteroid struck, Charles Frankel explains, it set off a wave of cataclysms that wore away at the global ecosystem until it all fell apart. What if there had been a way to slow or even turn back these tides? Frankel believes that the answer to this question holds the key to human survival.
Human history, from the massacre of Ice Age megafauna to todays industrial climate change, has brought the planet through another series of cataclysmic events. But the history of mass extinction together with the latest climate research, Frankel maintains, shows us a way out. If we curb our destructive habits, particularly our drive to kill and consume other species, and work instead to conserve what biodiversity remains, the Earth might yet recover. Rather than await decisive disaster, Frankel argues that we must instead take action to reimagine what it means to be human. As he eloquently explains, geological history reminds us that life is not eternal; we can disappear, or we can become something new and continue our evolutionary adventure.
