According to the book of "Genesis," the creation of the world and the creation of beings happened within a week. Today, based on science, we know that these two milestones are unimaginably far apart! The evolution of Earth's biosphere can now be traced back several billion years. The future of our physical universe is considered even more extensive, perhaps even infinite. However, despite these expanded horizons, both the past and future timelines have shrunk. Pessimistic estimates of how long our civilization must endure before it collapses, or even before it experiences a final "apocalypse," are becoming increasingly intense every day. The Earth itself may endure, but humans will not survive the scorching of our planet by the dying Sun, nor perhaps the depletion of Earth's resources.

In the twenty-first century, humanity is more at risk than ever from the misapplication of science. And the environmental pressures caused by collective human actions could trigger disasters more threatening than any natural hazards.

Our primary concerns naturally relate to the fate of our current generation, and the goal of all is to find a way to reconstruct the threats to the future of humanity. But for me, and perhaps for others (especially those without restrictive religious beliefs), a cosmic perspective reinforces the imperative to cherish this "pale blue dot" of the universe.

The subject of this book is directly related to the fact that humanity is at greater risk than at any previous phase in its history. The wider world has a potential future that could even be infinite. But will these vast time periods be filled with life, or will they end up as empty as the first barren seas of Earth? The choice may depend solely on us, and the game is now being played seriously, this century!
