As the question was originally put in the famous Drake Equation
(formulated in 1960-1961 by Frank Drake, Professor of Astronomy and
Astrophysics at the University of California—Santa Cruz), what is the average
lifetime of a civilization advanced enough to be detectable by intelligent
beings located on other planets? In answer to that question if polled on the
streets, many if not most Americans would likely express the opinion that it
would last thousands of years. But, what if, as the historian of science, Michael
Shermer, predicts, the average lifetime of a technological civilization is only
300 years?
A logical follow-up question is, why would high-tech civilizations only
last a relatively short time? If we use our present circumstances as a guide,
many might conclude that technological civilizations that fail do not recognize
until it is too late that the civilization had become ecologically unstable and
self-destructive. In other words, by the time a species has developed
technology capable of communicating with intelligent life on other planets,
they most likely also have created and are using that technology to destroy
their environment and thus the foundation of their civilization. The dark
thought we must consider is that when short-term economic gain (meaning
self-centeredness and greed), ignorance, indifference, and system-wide
inertia—once a system has moved in a specific direction in terms of allocating
resources it is extraordinarily difficult for it to change direction—take
precedence over ecological health, the results are predictable, disastrous, and
nearly impossible to reverse.
That prospect means that the far greater majority of all high-tech
civilizations might disappear within 300 years of becoming high-tech owing to the
above listed self-destructive propensities. The bottom line is whether Earth’s
current civilization has what it takes to work through the technology-ecology
conflict we are currently experiencing to the other side in a way that ensures
survival for thousands of years. To aid this mini-test, we’ll assume our base
year for calculation is the approximate start of the Industrial Revolution, 1800
CE.
The reality should be easy to see. In today’s America, many millions
believe global warming/climate change, smart growth, green development, and
sustainability are made-up nonsense and constitute socialist attacks on
individual freedom, liberty, and property rights. Many if not most of those same
people also believe that their elected representatives should get rid of the US
EPA or, at the very least, scale it back until it is ineffectual in preventing
corporations from doing whatever they please in terms of the environment.
In the U.S. today, many millions are determined to stop or eviscerate federal
programs that address the 5.14 billion metric tons of CO2 (2017 estimates)
Americans inject into the atmosphere every year. They are determined to ignore
the meaning of methane released by the Arctic’s melting permafrost, deny the
rapidly increased rate of melting of Greenland’s glaciers and Arctic sea ice,
deny the implications of ocean acidification and heating, and ridicule the
science that documents the rapidly changing geographic range of species that
result from global warming.
Who are the people who sneer about global warming? They are voters who
have given rise to the current malaise in the White House and in Congress. Americans
like them form what is perhaps the most critical reason the U.S. has rejected
coherent and effective policies to decrease air and water pollution,
biodiversity loss, and environmental destruction that threaten our prosperity
and our quality of life. People holding that worldview have elected national
representatives who refuse to allow the U.S. to engage in international
agreements that seek to cut CO2 emission on a global scale.
Although most of us don’t want to think about it, my personal conclusion
is our high-tech civilization has already hit the critical tipping point and is
on the decline. On those rare occasions we do think about it, we tend to throw
up our hands in frustration because solutions are too hard to figure out or too
far into the future to worry about. Yet, in reality, we seem hell-bent on
ensuring Carl Sagan's chilling but prophetic words are fulfilled: “Extinction
is the rule. Survival is the exception.” The trouble is the vast majority of us
just want to go on living the sweet life as though tomorrow will never come and
we will never have to pay the price for our profligate behavior.
Guess what. That tomorrow is around the corner but it will affect the
coming generations far more than us. You should be relieved if you are more
than 30 years old in 2018 but not so relieved if you have children or if you
are over 65 and have grandchildren. Those children are the ones who will have
to live with the decisions we’ve made. Isn't it comforting for us to be able to
push the risk into the future and on someone else and not worry about
consequences?
With all the physical evidence, it is hard not to see a bleak future
when you look at our present conditions. Acidifying oceans. Rising sea levels. Warming
climates. Increasing drought. Dying coral reefs. Increasing mercury levels and
anti-biotic resistant diseases. Every place on Earth has been adversely
affected by human agency. Countless species have been lost; others are
endangered and are standing on the brink of extinction due to habitat loss.
The way our species has developed over the last several hundred thousand
years has ensured we focus the far greater majority of our attention on
immediate or short-term challenges, like threats to our current well-being, and
basically ignore long-term, slowly emerging issues, like climate change, habitat
destruction, or global population growth. What was once an evolutionary
advantage has morphed into something far different, far more deadly to our
survival.
Here’s my prediction. We are a species with nearly countless individuals
who are willfully blind to the consequences of our current actions and will
wind up destroying our high-tech civilization with a fatal combination of greed
and indifference. Our epitaph should be:
Although once we ruled the Earth,
we lacked the intelligence to survive.
