A former EPA official has hailed outgoing Secretary of the Interior Zinke as a policy hero for his final act in office, and said that last week's shutdown of the Colorado River has put an end to upriver human trafficking by "wetdeck delta coyotes" running boatloads of methamphetamine and gang members into the American heartland from Mexico's Sea of Cortez. The official, who spoke on condition of anonymity, emphasized that the shutdown was " a win-win " because it also cut the downstream flow of deadly plastic drinking straws into the Pacific Ocean.
