They say that history repeats itself. The strictest form of the claim is like the world view of the aboriginal Yir Yoront, for whom every generation is a repetition of the one before. Even if our Western world view cannot admit such stasis, many people would say that the rise and fall of civilizations is a story that has repeated itself many times, and many future civilizations will walk on the ashes of this one.
However, when it comes to the history of human civilizations, history will never repeat itself again. Our species is on a one-way road, and if our global society collapses, no future Homo sapiens will enjoy the benefits of industrialized society.
Empires may rise and fall, but the modern world is intrinsically interconnected, and as a civilization we rise and fall as a globe. We are interdependent: were it not for international trade, most regions could not feed themselves, much less build and support their own industries. The stories of future history are confined to a single narrative.
So what happens if the global economy collapses and trade ceases, and each region is left to pick up the pieces on its own? These enclaves would not have the benefits of readily available resources that our ancestors enjoyed when they started our journey in industrialization. We have exhausted readily-available high energy sources: new sources of energy, like shale gas and tar sands oil, require immense technology to access. They would be trapped in perpetual pre-industrialization.
Add to this the harsher climate, destabilizated ecosystems, and exhausted ores that we are bequeathing to them, and their lives will be mean indeed. The planet will recover, given 50 million years or so, but far too late for our species.
What if we colonize other stars, with virgin resources and the room to collapse at our leisure? Those planets will have their own stories, and maybe there we can avoid becoming to big to fail, but colonization is a one-way process. Without a way to travel or communicate faster than light, our futures will be disconnected.
By the way, this also limits our use of any Prime Directive on Earth. Non-industrialized cultures cannot achieve development on their own-- not that any culture ever did. We are in this story together, taking it forward because there is no way back.
So, let's celebrate our dependence. Our lives and the lives of all our descendents depend upon it.
