A German submarine that sank off Denmark in 1917 still holds over 4,400 pounds of TNT; scientists find explosive leaking into North Sea

The wreck of a German submarine, UC-30, which sank off Denmark in 1917, is leaking over 4,400 pounds of TNT into the North Sea, according to scientists. This discovery has raised concerns about the potential environmental impact on marine ecosystems, as local sea life is absorbing explosive compounds. Danish divers are currently collecting water, sediment, and marine samples to assess the extent of this threat.
