Beneath the world's waters, an invisible crisis is deepening: dissolved oxygen is vanishing from oceans, lakes, and rivers at a pace that scientists now place alongside climate change as a civilizational threat. Driven by warming temperatures, agricultural pollution, and disrupted water circulation, this silent suffocation is already reshaping life in places like Lake Victoria, where nearly half the lakebed periodically loses the oxygen that fish and communities depend upon. The crisis does not announce itself with floods or fires, yet its consequences — collapsing fisheries, rising food price
Global oxygen crisis in waters threatens fish supplies and food security
Fishing communities around Lake Victoria, particularly women fish traders, face declining incomes and food insecurity as fish catches shrink due to oxygen depletion and environmental degradation.
