A months-long water contact closure for Tijuana Slough National Wildlife Refuge and Border Field State Park shorelines has been lifted.
The shoreline from the U.S.-Mexico border to the south end of Seacoast Drive in Imperial Beach was closed because rainfall was pushing sewage- contaminated flows from the Tijuana River into the United States, according to the county Department of Environmental Health.
President Trump's promise to build a "great wall" along the US-Mexico border remains one of the central and most controversial promises of his presidency. But scientists from the University of Arizona are starting to unravel the effect that such a wall could have on a desert ecosystem it will cut through. The team is studying wildlife in the Sonoran Desert, which stretches across the border from Arizona into Mexico and is already divided by a barrier at the border. BBC science reporter Victoria Gill joined the team in a search for some of the desert's most endangered animals.
