Where here ends

Most of our sense of what is acceptable was formed for a small world. A village, a street, a family. In a small world, what one person does stays roughly where they did it.

A family that drives out past the edge of Riyadh for a cool night of camping and leaves a few bags behind the dunes is being careless, not catastrophic. The wind takes some of it. The sand covers the rest. One family is a small mark.

But there is no longer one family. There are thousands of cars on the same tracks every weekend in the cool months, each one making the same small decision, each one feeling it is only them.

The same arithmetic runs through a lot of ordinary life. Is one message to everyone in your contacts a harmless nudge, or a habit that, multiplied, turns every phone into noise? Is leaning on the horn at a green light rude, or just loud, when a whole city does it at once? Is a seller pushing something he knows does harm wrong in a single sale, or only in the millionth?

Our instincts do not answer well, because they were tuned for a place where the consequences came back to your own door. Now they mostly land somewhere else, on someone we will never meet, and they arrive in bulk.

So where does my patch stop and everyone else's start? At what point does my freedom become somebody else's problem?

I do not think there are tidy answers. I do think these questions have stopped being philosophical. At this scale, they have become urgent.
