Ocean Deoxygenation
Ocean deoxygenation, also known as hypoxia, is a growing issue caused by climate change, pollution, and nutrient runoff from agriculture. This process reduces the amount of dissolved oxygen in seawater, posing serious risks to marine life.
Many marine organisms, including fish, crabs, and other invertebrates, rely on dissolved oxygen to survive. Low oxygen levels can also trigger the release of toxic chemicals, such as hydrogen sulfide, which further endangers marine ecosystems. Hypoxia can disrupt food chains, leading to cascading effects that reduce biodiversity and overall ecosystem productivity.
Addressing ocean deoxygenation requires concerted efforts to reduce greenhouse gas emissions, minimize pollution and nutrient runoff, and protect critical marine habitats to sustain healthy and resilient oceans.
