During WW2 the German Army placed 1.4 million landmines on the south-west coast of Denmark as part of their defence line. Until recently approximately 10,000 remained in an out-of-bounds area on the peninsula. Amazing! Shifting sands, the drift of the sea and local wildlife made it difficult to clear the area.
The minefield was finally cleared in 2012.
Another good news story. Unfortunately the clearing work still goes on in many countries around the world.
