Here’s another: All of us humans have myriad other species to thank. Without them, we couldn’t exist. It’s that simple, and we can’t afford to ignore them, any more than I can afford to neglect my precious wife—nor the sweet mother Earth that births and hold us all.
Without us, Earth will abide and endure; without her, however, we could not even be.
~Alan Weisman, The World Without Us
