Book excerpt: The Anthropocene defines the here-and-now time period on Earth of indelible (and possibly irreversible) human disturbance to the natural world, from habitat destruction and mass extinction to global climate change. To ameliorate and repair the damage that threatens the world's dwindling resources and our very existence, humanity is enacting massive interventions to fuse modern technologies with long established natural processes. Advances in genetic engineering have put us on the cusp of directly shaping the DNA of every living organism (including ourselves), as well as determining the evolution of completely novel species. The author invites the reader to explore how humans have manipulated the ancient forces of evolution and the future possibilities of genetic engineering for conservation and rewilding, de-extinction, and even the creation of viable populations of entirely new species. To entertain such possibilities of synthetic biology, he forces us to wrestle with the threats and ethical conundrums that surround the unintended consequences, as well as the values that humanity places on authenticity in nature. In so doing, this accessible and thought-provoking book explores the potential future of life on planet Earth.
