Eco-anxiety is a form of anxiety triggered by a sudden awareness of the path to destruction that the world is taking. It might be the latest announcement on the number of species that are disappearing or the amount of water that is headed our way from the melting ice in our retreating glaciers, but whatever it is it produces panic attacks and depression, probably made worse by a feeling of helplessness. It is also referred to as climate anxiety.
Associated with eco-anxiety is climate grief, which adds to depression and anxiety a sense of deep sadness about the state of the world. The sight of a young girl sobbing as she demonstrated to persuade the government to do something about climate change was a clear example of climate grief.
