The need for biodiversity champions in psychiatry: the entwined crises of climate change and ecological collapse

The past 20 years have seen the disappearance and degradation of biodiversity on earth at unprecedented rates. This phenomenon shares similar drivers to those behind climate change yet requires its own solutions. The twin catastrophes of climate change and biodiversity loss demonstrate how our health is bound up in the vitality of this planet. There has been an increasing effort on the part of healthcare professionals to appreciate this relationship, as evidenced by the growing influence of planetary health as a discipline. However, the health impacts of biodiversity loss have been less focused on than those brought on by climate change. Psychiatry's appreciation of the interface between environments and our health, alongside the evidence for the connection between nature and mental health specifically, prompt psychiatrists to ensure that the institution of healthcare throws its influence equally behind solutions to climate change as well as biodiversity loss.
