Pondering the Future of Earth

(originally published in the Ukiah Daily Journal May 24, 2015)
Despite my retirement from teaching last June, I’ve continually realized how much is still to be learned – and taught in life. One of my favorite activities is what I call “mind meandering” here on this small earthen ball spinning in airless, chunky soup which we call space. Ahhh, here we go a-meandering…
Space, the last frontier – a nod to my fellow Star Trek fans – is a huge something to ponder with our little minds. All of those existential questions usually come to the surface: How did we get here? Where is here? Why am I here? Etc, etc…
Believe me, I have no answers, just theories – which is all anyone could really have, since we’ve not been able to view our universe from another vista point or read a book written by a space traveler (sorry, Douglas Adams’s Hitchhikers Guide to the Galaxy  doesn’t count as a reference book on this subject).
Although noteworthy earth and sky students Copernicus and Galileo studied and questioned our universe five hundred years ago, it has taken many more scientists and their proven theories since then to bring us to our modern understanding. The caveat is that a few more hundred years from now, humans will look back and again realize how much is yet to learn.
As I substituted for a middle school class teacher last week, I was impressed by the passion of a young student in the class, Jade. Hopefully, we all were made aware of how much we humans must continually learn during the lesson. We watched a video on Galileo, a practicing Catholic and amazing stargazer who chose to believe the facts of his heavenly studies which clashed with Church doctrine at the time, unfortunately transforming the Church into his nemesis.
Galileo claimed, “I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forgo their use.” A good philosophy even today.
Since humans have only been on this planet for a relatively short time, neither the medieval nor modern age has dealt with cataclysmic changes. It seems our planet has spun for millions of years between those earth-changing events. Yet, from many pulpits as well as scientific platforms, various authorities pontificate on the possible modes of destruction for which we are bound as a planet. But when? Some may say next month; others may predict major earth disasters a few millennia from now. Who knows?!
The big questions we’re asking today is HOW will we do ourselves in – will it be Fire or Ice that makes life on earth impossible? (poet Robert Frost has a comment on that.) And, what can we do to keep it from ending badly? Hmmmm.
Multiple storytellers have too many possible scenarios to count. And, scientists cannot come to a consensus on this point, either. It is one of the big mysteries - - and I hope we’re wasting our time and imagination, to be honest.
Post-apocalyptic movies have been around since the 1930’s, starting with Deluge and Things to Come – what? Never seen them?! Maybe you’d like more recent films like Mad Max – Fury Road (2015) where you’ll hear, “My name is Max. My world is reduced to a single instinct: Survive.” OK.
Or there’s a more plausible television series, Revolution, where a universal power blackout makes surviving too difficult for most who are dependent on electricity and internet; despite being violent and back-to-basics, it imagines that some of us would be on a “journey of hope” and a rebirth of sorts. Check it out on Netflix – only two seasons, 2013 and 2014.
I would like to think that we can continue to adapt and create ways to manage what’s happening to us and our home planet. It’s what we’ve been doing as a species since we came into existence.
In recent history, modern humans moved from problem areas like the Dust Bowl after long droughts or rebuilt populations and cities after Black Deaths and World Wars.
Some interesting studies mentioned in a Time.com article explore the idea that many of our human physical changes are due to not only genetics, but also to our cultures. The National Academy of Sciences posed that cultural factors tend to have much more prominent impact than natural selection in the shaping of future generations. So, everything from what we eat for lunch and the number of our offspring could affect the future of our species - as well as a lack of rainfall and ozone changes!
Should we make changes in our behaviors to do less damage to the future of young Jade and her descendants? Of course, but will that be enough? And, if it’s not, can we load up and move to a healthier planet somewhere in the heavens? Maybe. Who’s to say that will not be possible in another millennium?! Look at all the changes in us and our home since modern homo sapiens evolved about 100,000 years ago.
