Opposition is growing at plans to dredge a UK sandbank known as the "ship swallower".
The 16 km stretch of Goodwin Sands lies 10 km off Kent in England.
The notorious sandbank is believed to have claimed hundreds of ships over the centuries, as well as downed aircraft from the World War II.
Now Dover Harbour Board (DHB) wants to remove millions of tonnes of sand and gravel to expand the port, endangering marine protection pledges, according to green groups.
