A Pale Blue Dot*

These days, two major themes dominate the news: violence and climate change. There is endless news about wars, bomb explosions, vehicles mowing down pedestrians, or armed men shooting or randomly stabbing people to death. Every day, too, you can hear news about how huge parts of forests are being cleared, the thinning ice sheets, the rising temperature, or the extinction of a species. Regardless whether you watch the local or international news, you are sure to find at least one story connected to either of these two.

Times like these, I cannot help feeling fearful for the future — if humankind even still has one considering the rate of how people destroy each other and nature in the name of politics, power, and so-called progress. If only people realized that all those are insignificant in the grander scheme of things.

In 1994, Carl Sagan, an American cosmologist and author wrote the book, “Pale Blue Dot: A Vision of the Human Future in Space,”* and in it, he gave a different perspective of Earth, a perspective I wish all people would appreciate.

“From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us.

On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner.

How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.

Our planet is a lonely speck in the great enveloping cosmic dark.

In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate.

Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.

To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we’ve ever known.”
