From the back cover:

When some future historian shall sit down to summarize what the present generation of Americans has accomplished, his climactic sentence could read, "Of the waters, they made a cesspool; of the air, a depository for poisons; and of the good earth itself, a dump where rats nuzzled in piles of refuse."

In the same mood he may write on: "Fixated upon the idea of production -- even knowing their god as the Creator -- they curiously forgot everything thus produced must be either returned upon itself that the cycle could continue, or else must be given proper disposal. Indeed they cheaply polluted their environment -- earth, air, and water -- until there remained no decency of life. For who dares his death willingly to defend a garbage dump? So, finally -- seeing disorder and ugliness, drinking from tainted streams, breathing stench, and choking on fumes -- as a people, they shriveled. And their land lay, for a while, desolate."
