“This effort will only intensify in the years and decades to come as we go from being space-bound again to even Moon-bound and Mars-bound with our eyes set forward to being a galactic species.”
Carl Sagan’s ‘A Pale Blue Dot’ Speech
As much as we try to ignore it, pay it no thought, or just let it fade into the background of our priorities, Planet Earth is our only current and future home. When I say ‘future home’ as well, I may be met with some skepticism given the exciting recent events in putting man and woman back into space with success. This effort will only intensify in the years and decades to come as we go from being space-bound again to even Moon-bound and Mars-bound with our eyes set forward to being a galactic species.
However, while this excitement is commendable and our goals of being an interplanetary species a revolutionary event that could transform human life, I think we all need to remember that even though this effort to touch down on other planets including Mars may be a decade away, it will be quite a while still where people in large quantities can explore, live, and settle down in a planet not named Earth. You can practically guarantee that by reading this article in the year 2022 that it is very remote that we will be able to see humanity transcend Earth to live on other Earth-like planets in our lifetimes.
While I personally believe that Earth in our galaxy is not the only habitable planet, finding one that is, being able to go there, and then sustaining ourselves there will be the challenges of not years or decades but centuries forward. It is a noble pursuit and one that is likely to occur in the far future. My concern during this renewed era around space travel and interplanetary focus is that we stand to lose our only planet’s hospitable climate while we try to find others like the current one, which we are so blessed to have.
Multiple reports out there especially recently cite that we may be past the point of no return already when it comes to pulling the planet back from the depths of climate change activity already in motion. Our Planet Earth or as the great Carl Sagan would say, the ‘Pale Blue Dot’ is in danger of only having a century or less left where it is hospitable for humans to live there comfortably. Natural disasters are clearly getting worse, droughts, wildfires, flooding, torrential downpours culminating together to create something out of a Biblical prophecy on top of the fact that the Polar ice caps melting has accelerated alongside unseasonably warm temperatures in the Arctic.
While we marvel at putting impressive rockets into space that can land vertically after being thousands of miles away, our planet is going through a stage five fire alarm and basically ringing the warning signs for us to collectively do something about the current climate crisis. We do not know how fast this crisis will accelerate and how bad it will get and when it will be unsustainable for Earth to be a hospitable planet, but we can measure that in decades and not centuries. We race to get to space and to find a hospitable planet other than our neglected and vengeful home of record, but we are at a disadvantage in my view. We do not have centuries to fix our climate crisis, but mere decades or even a decade as some have argued. Our ability to find an Earth-like planet for which humanity would have to relocate in mass would not take place for centuries and not decades.
I am not writing this article to solve the climate crisis or to illustrate what we all should do to combat it; I believe we know what to do in our lives and what we should tell those in power to implement but rather my fear is that we have lost sight of the importance of why Planet Earth is so precious and worth fighting for. There is no better illustration of the gravity of our current fight to save Earth than the humble video recorded speech of the late famous American astronomer, Carl Sagan, who summed up the sheer importance of why ‘here’ or ‘Earth’ matters so much in the grand scheme of the Cosmos. “That’s here. That’s home. That’s us.”
The ‘A Pale Blue Dot’ speech by Mr. Sagan highlights the totality of how Earth captured the human experience from across the globe among the tens of billions of people who lived on our planet including every hunter, forager, creator, destroyer, king, peasant, mother, father, and hopeful child. Everyone who has existed has lived on Earth on a ‘mode of dust suspended on a sunbeam.’ Mr. Sagan highlights the cruelties and violence that we have committed and continue to commit against each other to control a small part of the ‘pale blue dot’ we call Earth. The delusions of grandeur, the great ego we all struggle with, and how we think of ourselves as greater than the vastness of space and the endless infinity that surrounds us outside of our banal conflicts and glories.
Carl Sagan makes the point that in 2022, “The Earth is where we make our stand.” We can visit other planets like Mars or our own Moon, but we cannot live there yet. Mr. Sagan highlights the need to preserve and cherish ‘the pale blue dot’, which is still the only home we have ever known. To be kind to one another, to treat one another with respect, and to realize that the significance of our lives and of our place in the universe is quite minimal when you consider the vast never-ending spectrum of the cosmos. The Voyager 1 took the photo of the miniscule ‘pale blue dot’, otherwise known as Earth, over thirty years ago on February 14th, 1990, which inspired Carl Sagan’s speech and then book on what it means to see Earth from space to realize how small yet precious it is to have our home in the galaxy, and that it is the only known one we have in our universe.
As much as we try to distance ourselves from the fact that we are quite small and insignificant outside of ‘pale blue dot’, we occasionally should use that photograph to remind ourselves of how significant the Earth is to humanity and how we would not be surviving as a species without it as our home since the dawn of man and woman. If we choose not to preserve and protect for future generations, it will be a sad day with ancestors henceforth will have to leave a dying Earth to hope for a ‘better’ world, which may not even exist for us. All the love, death, goals, hopes, dreams, pain, pleasure of what it means to be human has taken place on our only home of Earth. The speech was a wakeup call to people in 1990 to take our only home of Earth more seriously and it will continue to be that clarion call for 2022 and beyond as the warning signs grow louder and more ominous if actions are not taken to combat the climate crisis.
While the movement to preserve Planet Earth has been around since at least the 1960s with the growth of environmentalism, Sagan’s ‘pale blue dot’ speech has inspired and continues to inspire those of us who realize how grave of an existential threat climate change is to humanity and how vital it is to protect this only home of ours. Sagan would not argue with those people who are trying to get us into space currently and to the parts unknown of our galaxy, but he would also remind us not to neglect our only home, not to abandon it to certain devastation, nor destruction, and to fight to keep it as a hospitable home for future generations. “Every human, who has ever lived, has lived on Earth,” he makes clear in the ‘pale blue dot’ speech and if the Earth is thriving, humanity will also have the chance to thrive too.
