There are many "ends", the world has been here through more than a few.
We are in a circular renewal of humanity, and we are right in schedule. A crisis will happen, mother earth will trump us all and we will be forced to reexamine, reaccess and find new ways to interact, new ways to convene and new ways to understand our existence. It will be earth shattering - no pun intended. Forget what you think you know, forget it all, we have consumed too much of everything and now we must start anew in our minds, and in our psyche.
And only the strong will survive.
