Researchers have identified more than 1,000 barrels of nuclear waste on the seabed of the northeast Atlantic Ocean, including off the coast of Galicia, Spain. These barrels, some dating back over four decades, are remnants of wartime and post-war nuclear disposal practices by various countries. A French expedition recently geolocated over 1,800 radioactive barrels near Galicia, following the discovery of an additional 600 barrels in the area. The containers are deteriorating, raising concerns about potential leakage and environmental risks to marine ecosystems. The issue highlights the ongoing environmental threat posed by decaying war-era ships and their toxic cargoes on the ocean floor, which has often been overlooked by authorities.
