 Grieving all lives, one by one 
To what extent can the culture of memory forged in the wake of twentieth-century historical disasters inform the narrative of non-human loss ? In this period of mass extinction of animal and plant species, the slaughter and disappearance of other forms of life affects culture in terms similar to those of mass death : grief, melancholy, immeasurable loss. But this extension of the domain of grief to non humans raises multiple problems. How can we remember all the animal and vegetable lives lost, one by one, when the experience of so many human lives already escapes us ? How could literature or social sciences repair losses that we only apprehend in masses, or not at all?
