"Joel Greenberg plays the role of scientist in A Natural History of the Chicago Region, exhaustively and objectively listing what was here. Sometimes with a heavy heart, and sometimes with humor, he explains who changed it, who destroyed it, who preserved it, and what we should do about it now. . . . It sticks with you when you look at the ground, or at the water in the lake (and in your glass), and at the plants and trees all around. When you go fishing, when you go hiking, when you go to work. Because you know what's 'supposed' to be wherever you look."
