Ecological grief
Ecological grief (or eco-grief), or in particular climate grief, refers to the sense of loss that arises from experiencing or learning about environmental destruction or climate change. Environmental grief can be defined as "the grief reaction stemming from the environmental loss of ecosystems by natural and man-made events." Another definition is "the grief felt in relation to experienced or anticipated ecological losses, including the loss of species, ecosystems, and meaningful landscapes due to acute or chronic environmental change." For example, scientists witnessing the decline of Australia's Great Barrier Reef report experiences of anxiety, hopelessness, and despair. Groups impacted heavily also include young people feeling betrayal from lack of environmental action by governments and indigenous communities losing their livelihoods.
It was among the strongest feelings of grief I have ever encountered. The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna... things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind. It filled me with dread. My trip to space was supposed to be a celebration; instead, it felt like a funeral.

Environmental disruption, such as the loss of biodiversity, or even the loss of inanimate environmental features like sea ice, cultural landscapes, or historic heritage can also cause negative psychological responses, such as ecological grief or solastalgia.
