Evolution, energy, and ethics are the core elements that will guide us along the challenging path toward the Life Era: the first - evolution - because a good understanding of our universal roots and of our place in the cosmic scheme of things will help us create a feasible future course; the second - energy - because our fate will bear strongly on the ways that humankind learns to use energy efficiently and safely; and the third - ethics - because global citizenship and a planetary society are crucial factors in the survival of our species.
