People always think there's this huge hundred-foot-high barrier that separates doing good from doing bad. But there's not. There's nothing. There's not even a little anthill. You just take one baby step in any direction and you're already there. You've doing something awful. And your life is changed forever.
I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer. And perhaps with better cause, for while a buck pulled down by wolves can be replaced in two or three years, a range pulled down by too many deer may fail of replacement in as many decades.
