There is, unfortunately, only one Planet Earth, or Spaceship Earth, if you prefer, since we’re all traveling through our galaxy on it. Thought about a certain way, we’re its crewmembers, yet instead of cooperating effectively as its stewards, we seem determined to fight one another. If a house divided against itself cannot stand, as Abraham Lincoln pointed out so long ago, surely a spaceship with a disputatious and self-destructive crew is not likely to survive, no less thrive.

In other words, in waging endless war, Americans are also, in effect, mutinying against the planet. In the process, we are spoiling the last, best hope of earth: a concerted and pacific effort to meet the shared challenges of a rapidly warming and changing planet.

Spaceship Earth should not be allowed to remain Warship Earth as well, not when the existence of significant parts of humanity is already becoming ever more precarious. Think of us as suffering from a coolant leak, causing cabin temperatures to rise even as food and other resources dwindle. Under the circumstances, what’s the best strategy for survival: killing each other while ignoring the leak or banding together to fix an increasingly compromised ship?
