Why don’t we grieve for extinct species?

We have no rituals for coping with extinction, ecological destruction or environmental loss. And that's a problem. Now, an impassioned group of artists and activists are trying to create them.

In early 2010, artist, activist and mother, Persephone Pearl, headed to the Bristol Museum. Like many concerned about the fate of the planet, she was in despair over the failed climate talks in Copenhagen that winter. She sat on a bench and looked at a stuffed animal behind glass: a thylacine. Before then, she'd never heard of the marsupial carnivore that went extinct in 1936.

"Here was this beautiful mysterious lost creature locked in a glass case," she said. "It struck me suddenly as unbearably undignified. And I had this sudden vision of smashing the glass, lifting the body out, carrying the thylacine out into the fields, stroking its body, speaking to it, washing it with my tears, and burying it by a river so that it could return to the earth."
