The Solomon Islands' caretaker Prime Minister Rick Hou is threatening to "blacklist" the companies involved in a 100-ton oil-spill near a UNESCO World Heritage Site. "My government is prepared to go as far as putting the companies on a black list internationally if they do not take on their responsibilities," he told a press conference March 7, without elaborating on how this would actually sanction the companies involved. He did say the lease for the Bauxite mine could be suspended. Hou, who faces an election next month, has called in Australia's assistance to clean up the spill, which he described as causing "irreversible damage," acknowledging his country's resources were inadequate for the task. "The impact on the marine life and the coral is already massive with much of it irreversible," he said.
