The canaries in the coal mine are there as a warning to us, and THEY ARE DYING.
The dying of canaries, of delta smelt (tiny fish ridiculed by anti-environmentalists) and other species large and small are warning that we, too, will have our day.
Almost all large mammals that existed at the dawn of human civilization have been hunted to extinction, and the few large mammal species that still remain (elephants, rhinos, hippos) are all teetering on the brink.
Previous mass extinctions were caused by external forces.
The mass extinction now in progress is caused by human activity.
Humans are killing off our fellow earthlings of other species.
