" We can only miss what we once possessed. We can only feel wronged when we realize something has been stolen from us. We can’t miss the million-strong flocks of passenger pigeons that once blackened our skies. We don’t really miss the herds of bison that grazed in meadows where our suburbs stand. And few think of dark forests lit up with the bright green eyes of its mammalian lords. Soon, the glaciers will go with the clear skies and clean waters and all the feelings they once stirred. It’s the greatest heist of mankind, our inheritance being stolen like this. But how can we care or fight back when we don’t even know what has been or is being taken from us? "
