The other day, I found myself in a conversation about violence. We were discussing gun ownership, the right to self-defense, and the morality of war. It seems that perspectives on violence often depend on which side of the conflict you're on.
This got me thinking about why violence persists in our world. Almost everyone agrees that war is bad, that peace is preferable. Most religions and philosophical movements advocate for non-violence. Even economists recognize the devastating impact of war on society. While some profit from conflict, the overall consequences are destruction, lost opportunities, and wasted lives.
Imagine how much further humanity would have progressed if we hadn't devoted so much time and energy to war. Think of the potential Einsteins lost, the cities destroyed, the resources diverted to rebuilding instead of advancing. If civilization is a dynamic entity, constantly growing and expanding its knowledge, then wars represent a tragic setback.
Looking back at history, it's tempting to conclude that violence is an inherent part of human nature. Wars have often driven technological innovation, with the threat of defeat and death spurring invention. As a byproduct, these advancements have benefited other areas of life.
This might sound like a cold, "survival of the fittest" argument, and I'm sure it will upset some. But Nietzsche wasn't wrong when he said, "What doesn't kill you makes you stronger." While he may have been referring to individual development, the principle applies to societies as well.
This brings me to the core of my argument: It's all about survival. Biology teaches us that life is driven by the urge to propagate, spread, and secure new territory. Evolution favors the species most adapted to their environment. Human society is no different. We use our brains to enhance our adaptability.
Initially, small human populations struggled against nature. As we grew more numerous and skilled at defending ourselves, nature became less of a threat. But then we turned on each other, driven by territorialism and the same primal urges as bacteria: spread and propagate.
But have we truly conquered nature? A glance at the bar chart on NASA's website listing Near Earth Objects (NEOs), or asteroids, reveals a sobering reality. Over 9,000 known objects are flying in Earth's vicinity. Can we truly say that nature, in the form of space, no longer poses a threat?
Dinosaurs and countless other extinct species would attest to the dangers lurking in space. Earth has experienced at least four mass extinction events, the last one wiping out the dinosaurs 65 million years ago. It's not a matter of if another catastrophic event will occur, but when.
This is why we must invest in space exploration. It's not just about humanity's survival; it's about preserving all life on Earth. Perhaps humans are the evolutionary step needed for life to transcend its planetary boundaries. As Robert A. Heinlein wrote in The Man Who Sold the Moon, "There is soo much space out there! So we don't have to suffocate down here."
The recent success of SpaceX's Dragon spacecraft, a private space endeavor, gives me hope. It's time to throw some diamonds on the moon and expand our reach beyond Earth. Our survival, and the survival of all life, may depend on it.
