I tried to find content about how relevant humans are to other life forms on earth and wonder what species (if there are at all) is totally dependent on humankind and would go extinct if we would vanish from the face of the planet?
This is probably a silly (and somewhat morbid) question. Yet how important are we to the ecosystem? Or have we managed to detach ourselves so far from mother nature during the course of evolution that we no longer matter?
