Where humanity is going, there are no roadmaps. The terrain is unlike anything we’ve seen before. The changes sweeping the Earth right now are literally planetary in scale and so filled with complexity that few among us even have a semblance of knowing what is actually going on. This makes it very difficult to navigate the troubled waters of the 21st Century.
Here are a few examples of things our species has not known in the three million years we’ve existed as “tool using” hominids:
- Emergence of a Globalized Economic System :: In the last 500 years, a vast web of intercontinental trade arose spanning several empires, evolving into nation-states, and now becoming a truly globalized meshwork of supply chains, trade agreements, human migration patterns, and so forth.
- Extraction and Consumption of Fossil Fuels :: The last time a species gathered up the waste products of a prior era and consumed them to grow itself we had a mass extinction event. And that was more than two billion years ago! I am referring to the cyanobacteria who excreted oxygen and changed the biochemistry of the Earth. Humans are doing this again by disrupting natural carbon cycles with the combustion of fossil fuels.
- Explosive Population Growth :: There are now more than 7.4 billion living human beings on Earth. Our population exploded in the last 150 years, well beyond anything in the history of our species. And now we are watching the rapid depletion of vital resources as this huge population gobbles them up — literally as food and metaphorically as the built environments of our globalized civilization.
- Crossing of Critical Planetary Boundaries :: The Earth has maintained incredible amounts of stability for billions of years through a vastly complex meshwork of self-regulating feedbacks. Thresholds exist (called “planetary boundaries” by the earth scientists at the Stockholm Resilience Institute) that if crossed will remove this self-regulatory capacity. There is now ample evidence that human activities have pushed us beyond as many as four of these critical operating boundaries for a globalized economic system.
- A New Pace and Scale of Complexity :: Most of our history was lived out in small tribal communities where each person might know as many as 150 people. Rapid changes, when they happened, were either catastrophic (volcano wipes out village) or disruptive (drought conditions cause the tribe to migrate into a new area). But they never happened at the pace and scale we live with today. As complexity scientists will be quick to tell you, scale matters a great deal! There are qualitative differences in the interdependencies, cascading patterns, and unexpected phase transitions for large, volatile dynamic systems — intuition about smaller systems misleads and confuses more than it helps.
- Entering A New Geologic Era :: Humans have enjoyed an unusual period of climate stability in which to birth agriculture, build cities, weave trade networks, and grow economic empires. That 11,000 year period is known by geologists as the Holocene. The same geologists now agree that human activities brought the Holocene to an end in the 20th Century. We are now in the “age of humans” dubbed appropriately as the Anthropocene. Our footprints on the Earth will be visible in the very chemical makeup of the planet’s crust hundreds of millions of years from now. This is how unprecedented this time in history really is.
