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 clumsy 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.

It is, What world do we want to create in its place?
