The loss of oxygen from the ocean due to climate change and nutrient pollution risks “dire effects” on sea life, fisheries and coastal communities, a global conservation body has warned
The International Union for the Conservation of Nature (IUCN) said on Saturday that about 700 sites had been identified globally with low oxygen levels – up from only 45 in the 1960s.
