"Vices and frailties correct each other, like acids and alkalies. If each vicious man had but one vice, I do not know how the world could go on."

We can break the mountains apart; we can drain the rivers and flood the valleys. We can turn the most luxuriant forests into throw-away paper products. We can tear apart the great grass cover of the western plains and pour toxic chemicals into the soil and pesticides onto the fields until the soil is dead and blows away in the wind. We can pollute the air with acids, the rivers with sewage, the seas with oil - all this in a kind of intoxication with our power for devastation at an order of magnitude beyond all reckoning.
