nobody will notice

Nobody would notice, nobody would care. If one grain of sand would disappear. Or if one star would stop shining. Neither would anybody search for one missing flower. Nor would anyone cry over one missing fish. I know for sure, that nobody would care if one ant would disappear. Absolutly nobody would be sad over one strand of hair was gone, if one leaf is less on a tree or if one fly less was alive. Nobody would notice, nobody would care. So why do all those things when one human out of 8 billion dies?
