the trump administration has declared a national emergency along the us-mexico border. construction of a new 30-foot-high steel border wall began in august, 2019 in organ pipe cactus national monument. environmental activists are calling this new construction a national tragedy and are mobilizing to prevent the ecological and cultural destruction of this unesco biosphere reserve on tohono o’odham tribal land. laiken jordahl, borderlands campaigner with the center for biological diversity, organized a protest against the border wall on the 30th anniversary of the fall of the berlin wall. jordahl believes that if enough people can mobilize and protest, a growing national movement can put pressure on the government to tear down the border wall and protect the 100+ endangered species that call organ pipe home.
