Biodiversity loss and climate change are the two most pressing issues of the Anthropocene. They are interconnected and need to be addressed together. Limiting global warming to ensure a liveable climate and protecting biodiversity are mutually supportive goals, and achieving them is essential to provide sustainable and equitable benefits to people. Unfortunately, most actions to preserve biodiversity rely on some action on plants and animals while an important kingdom, fungi, are ignored and given little consideration in planning despite the vital role they play. To support the emergence of actions for a productive, sustainable and resilient nature, the non-governmental organisation Fungi For Nature (FFN) was created to take into account fungi and their interactions.
