A few years ago, I took a philosophy course and one day my professor asked the students of the class to raise their hands if they would want to live forever. Not a single student raised their hand. No one but me, that is. I wasn’t sold on the whole immortality deal, but I was at least interested. I wondered if this hypothetical offer was enforced or endorsed. In particular, I wanted to know if I could choose to die at some point in the future when I’ve finished, or at the very least grown tired of, exploring the infinite expanses of both the universe and of the mind. His response was no, so my choice was no. Just as the eternal immortality of heaven and hell seemed unappealing to me, eternal immortality in our world was not a goal of mine.

But still, I chose to explore the possibilities. I thought for at least a moment that immortality would be a good thing. No one else did. What the fuck is wrong with everyone?

When I finally opened the door to that question, the professor asked a few others why they wouldn’t want to live forever and none of them gave the answer I thought. I assumed that most of them, being philosophy students, had thought it out in great details. But no, they all said it was because of global warming.

Global warming. Seriously.

More abstractly, they all talked about the disastrous effect humanity has had on earth thus far. They didn’t think they would want to live forever when 100 years from now the world would be a desolate wasteland destroyed by the cruel banalities of man. More reasonably some thought that earth would survive but humanity would likely be extinct in the near future and then they would be alone forever. To wit, a majority of the students believed not only that humanity would be gone within their lifetime, but that earth would be irrevocably damaged by us.

Our planet survived an impact with a Mars-sized planet. Without ten thousand more years of technological improvement humanity could not irrevocably damage the planet even if we tried. We could destroy the majority of life on the planet and possibly all of it, but life would grab hold again. It’s tenacious like that. That innate tenacity in combination with the intelligence of our species is what makes us the dominant species of our planet. We’ve made many mistakes over the millennia, and with each new generation’s greater reach and power those mistakes become more and more dangerous but we’re not done yet.

There has been talk recently of what might happen if the Yellowstone Caldera erupts as it did 640 000 years ago, because of a recent increase in tectonic activity there. The level of damage that would cause is beyond catastrophic. Ash from the eruption would blanket most of North America and change the climate of the entire planet in ways far more drastic than the accumulation of greenhouse gases we’ve contributed in the past 200 years ever could. It’s hard to imagine just how much the world would change because of an event like that, and yet I’m not worried for the future of humanity. I’d almost certainly die, but humanity would persist.

It seems like the environmentalists have managed to scare the shit out of the world. Gone is the quixotic optimism for the future of the 50′s, replaced by the dour nihilism of now. We talk of alien archaeologists examining our cities thousands of years from now wondering what killed us, but we’re not going anywhere.

We’ve reached a point in our evolution where our intelligence is almost a detriment. Given the comfort of our more base needs, we have more time to think and greater minds with which to think. And so we think of what can go wrong. Each new generation imagines new terrors capable of destroying us with their free time. These thoughts of dread can paralyze us with fear of the inevitable or they can spur us to imagine new solutions. Lately there has been far too much of the former and not enough of the latter.

Here’s what I know about the ultimate fate of humanity. We will go away. There will come a time when no humans exist. That is inevitable. But the question is when. Do we want to give up and whimper away in the next hundred years, or do we want to keep growing, keep getting smarter, keep fighting until the end, until the universe dies around us?
