During the campaign, President Donald Trump threatened to withdraw from NAFTA, calling it “a disaster since the day it was devised,” write Alyshia Galvez and Nicholas Freudenberg in an op ed in the Dallas Morning News. But last week, he said he will “bring NAFTA up to date through renegotiation.” However, neither Trump nor those on either side of the trade wars has given any hint that they know about one of NAFTA’s most distressing consequences: its adverse impact on the health of the Mexican people. For those who believe that fair trade agreements can benefit all, the goal should be a renegotiated NAFTA that puts the well-being of all North Americans first. A trade agreement that favors sustainable agriculture, labor mobility and a food system oriented toward health — not corporate profits — would be good for us all.
