Along a remote stretch of the U.S.-Mexico border, two visions for the climate-changed future are unfolding.
The U.S. Border Patrol agent was positioned behind a rust-colored vehicle barrier, on the other side of the international boundary line. He stopped when he saw me, bent down and taking a picture of grass. I was examining a tuft of sacaton, one of the several varieties of native grasses brought back to life by one of the largest ecological restoration projects on the U.S.-Mexico border, at the San Bernardino Ranch, located about 12 miles east of Agua Prieta/Douglas.
