UN calls for 'urgent action' over oceans' 'deepening crisis'

The UN warns of a 'deepening crisis' in the oceans, which cover 70% of the planet and are critical to the global ecosystem, urging urgent global action against threats like global warming, pollution, and loss of marine life. A five-year report by 600 international scientists highlights the risk of an ice-free Arctic as early as the 2030s.
