When did humans begin to need containment and separation? What happened to cause the first human to create a barrier with the intention to cause harm to another human or animal attempting to cross it? They say barb wire was invented by someone in Ohio in 1867, but maybe this was the first time someone claimed credit for the idea. But when I see barb wire, I see war, I see possible harm, I see alienation, separation, a big NO, you are not welcome here. And sadly, this is how we mostly live our lives today, with borders, with walls, with barb wire.
