A recent segment of the border wall constructed in southern Arizona has raised concerns beyond just immigration issues, according to the Center for Biological Diversity. The organization highlights that the wall and accompanying road in California Gulch are obstructing critical streamflow necessary for the survival of the Sonora chub, a rare desert fish.
The Sonora chub, described as a small, chubby fish with unique red coloration during breeding, is now facing the risk of extinction due to the new infrastructure. The Center's senior scientist emphasized that the fish's existence relies on accessing water sources on both sides of the border, genetic exchange with Mexican populations, and migration after droughts, all of which are hindered by the recent construction.
