That moment when you experience sudden and traumatic environmental change … your favourite tree being cut down, your forest has just died of heat stress, a wild fire is consuming your landscape, the bulldozer is demolishing your loved streetscape or you witness an oil spill that smothers all life on ‘your’ beach. This is not post-traumatic stress disorder; this is not chronic solastalgia, this is acute earth-based existential trauma in the here and right now.
We need a word for this gut feeling, this mental anguish. I think tierratrauma is a good first effort and it can be contrasted to eutierria, a concept I have already offered as a catch all for “that oceanic experience” or the feeling of oneness between self and nature. If we can have eutierria, then we can also have tierratrauma.
