Alarm at seabed destruction from SA phosphate mining

The Daily Maverick reports that the South African Department of Mineral Resources has granted three prospecting rights over vast areas of the sea floor that could signal the start of a process to grind up the seabed to extract  nada phosphate. The resulting sediment would be dumped back into the water column as liquid “dust”, posing a threat to ocean ecosystems, fish and fisheries. What it would do to the seabed is almost unimaginable.
