We live at a time in which scientists race to reanimate extinct beasts, our most essential ecosystems require monumental engineering projects to survive, chicken breasts grow in test tubes, and multinational corporations conspire to poison the blood of every living creature. No rock, leaf, or cubic foot of air on Earth has escaped humanity's signature. The old distinctions--between natural and artificial, dystopia and utopia, science fiction and science fact--have blurred, losing all meaning. We inhabit an uncanny landscape of our own creation. In Second Nature, ordinary people make desperate efforts to preserve their humanity in a world that seems increasingly alien. Their stories--obsessive, intimate, and deeply reported--point the way to a new kind of environmental literature, in which dramatic narrative helps us to understand our place in a reality that resembles nothing human beings have known.
