Marine life, fisheries increasingly threatened as the ocean loses oxygen – IUCN report
International Union for the Conservation of Nature
The loss of oxygen from the world’s ocean is increasingly threatening fish species and disrupting ecosystems, a new IUCN report warns. Ocean oxygen loss, driven by climate change and nutrient pollution, is a growing menace to fisheries and species such as tuna, marlin and sharks, according to the report released today at the UN Climate Change conference in Madrid.
