Poet, essayist and naturalist Diane Ackerman's new book "The Human Age" is a reflection on how people have changed the planet. She writes, "Our relationship with nature has changed...radically, irreversibly, but by no means all for the bad." While humans have "subdued 75 percent of the land surface," we have also collected DNA of vanishing species, manufactured body organs from 3D prints and gone to great lengths to restore ecosystems.
