Perhaps society’s biggest challenge, and arguably our largest failure, is the continuing loss of species from Earth.
We still have little idea of how many species exist on Earth. Only a fraction have been formally described, and even fewer assessed for their conservation status.
How do we conserve what we don’t know exists?

If Earth were a house, it would be as though we had listed the contents of only one room, and even then were not aware of their true value, while simultaneously the house was being demolished.
