“[Humans] are like an asteroid strike. We have the impact of an ice
              age.” Or perhaps a Thanos finger snap. In a geological instant, humans
              are causing waves of extinctions, changes to species, and upheaval in
              nature. Anthropo is Greek for “human,” so some scientists suggest we
              call our time the Anthropocene.
                  As evolutionary biologist Chris Thomas writes, “We are living on
              a fundamentally human-altered planet, and there is no longer any such
              thing as human-free nature.”
                  In other words, we have already transformed our world so radically
              and extensively that not doing anything isn’t really an option anymore.
              If we want to solve a particular problem or heal the damage we’ve
              caused, often our only choice is to keep transforming the world using
              every tool we have. While genetic engineering isn’t always the best or
              only option, we can’t avoid making decisions. Even choosing not to act
              has consequences.
                  Science journalist M. R. O’Connor writes, “Humans are in the
              midst of an unplanned experiment of influencing the evolution of the
              planet’s biodiversity. . . . And which animals we prioritize, and how we
              choose to save them, tinkers with the biosphere as a whole.”
                  Stewart Brand—the cofounder of Revive & Restore, which is
              helping de-extinct the passenger pigeon—captures this dilemma even
              more dramatically: “We are as gods and have to get good at it.”
                  Sure, Brand sounds like a Hollywood-ready mad scientist. But he
              describes the situation well. Genetic engineering has given us the power
              to alter life as we see fit, and if we decide to use it, we must get good
              at it.


              GENETIC ENGINEERING: NEW TOOLS
              FOR AN OLD GAME
              What exactly is genetic engineering? It often sounds like magic: a
              scientist tinkers with the unseen, swirls a beaker, and—poof!—a new
              creature is born.
