US envoy takes aim at illegal fishing

The United States on Wednesday put a spotlight on global efforts to combat illegal fishing at the UN ocean conference, steering clear of the controversy over its pullout from the Paris climate deal.

President Donald Trump's envoy to the conference, David Balton, said the ocean and its resources are "under tremendous pressure from a variety of threats - including illegal fishing, marine pollution, and ocean acidification."

"Illegal, unreported, and unregulated -- or IUU -- fishing around the world is jeopardizing international food security and economic growth, and threatening marine ecosystems," said Balton, the US deputy assistant secretary for oceans and fisheries.

The UN's first ocean conference opened Monday under the shadow of the US exit from the 190-plus nation pact aimed at combating global warming.

The United States, the world's biggest carbon emitter after China, signed the agreement last year under the previous administration, but Trump has argued that the deal would harm the US economy.

UN Secretary General Antonio Guterres opened the conference with an appeal to countries to put aside national gain to save the oceans and avert a "global catastrophe."

"Pollution, overfishing and the effects of climate change are severely damaging the health of our oceans," he asserted, singling out plastic pollution as particularly harmful.
