The scale of the biodiversity crisis laid bare
Briefly

Ehrlich and his colleagues present powerful evidence of global wildlife decline and more extinctions to come, underscoring the urgent need for conservation efforts.
The authors emphasize how population extinction leads to species extinction, exploring the cascade of effects within ecosystems, citing the Steller's sea cow as an example.
Grief for what has been lost permeates the book, with the authors sharing personal anecdotes that highlight the profound impact of wildlife decline.
The well-known extinction of the Steller's sea cow illustrates how the local extinction of one species can precipitate the demise of another, altering ecosystems.
