Whatever else might be said about the borderlands, one truth is indisputable: 111 fares the land. For this crime against nature, Americans and Mexicans share equal responsibility: The ongoing abuse is a binational enterprise, at times part and parcel of the global economy. As Peter Stein-hart warns in his book Two Eagles, the “fine ecological balance is tipping,” plunging toward its “complete destruction, until there will be nothing left but those new steel fences the U.S. Border Patrol is erecting to keep Mexicans out.” Man has laid waste to a remarkable region, where plants, animals, and the land interblend in a wondrous, strange symbiosis.
