Ocean deoxygenation, also known as hypoxia, is a growing problem caused by a combination of climate change, pollution, and nutrient run-off from agriculture. This phenomenon reduces the amount of oxygen available in the water, leading to severe consequences for marine life. Many marine organisms, such as fish, crabs, and other invertebrates, rely on dissolved oxygen to breathe and survive. Deoxygenation can also trigger the release of toxic chemicals, such as hydrogen sulfide, that can harm or kill marine life. Moreover, the disruption of the food chain caused by hypoxia can have cascading effects on entire ecosystems, leading to declines in biodiversity and productivity. Addressing ocean deoxygenation requires concerted efforts to reduce greenhouse gas emissions, minimize pollution and nutrient run-off, and protect critical habitats.
