Along coastlines from the Pacific Northwest to Scandinavia and Japan, archaeologists keep finding the same strange landmark, huge piles of shells mixed with ash, bone, and broken tools.

People use them for anxiety spirals, breakup grief, and everyday stress, often because a human appointment is expensive or weeks away. The ethical questions are no longer theoretical.
