Scientists have documented a significant decline in oxygen levels across Earth's waters, including oceans, lakes, rivers, and coastal areas. This deoxygenation threatens aquatic habitats and food chains, disrupting ecosystems.
It also compromises essential processes that regulate the global climate system.
Deoxygenation is closely linked to environmental problems such as global warming, pollution, biodiversity loss, and rising ocean acidification. These factors collectively degrade aquatic environments and heighten climate-related risks.
Experts stress the urgent need to tackle deoxygenation within broader ecological conservation and climate mitigation efforts to safeguard water quality and biodiversity.
