Healthy oceans are essential but are threatened by pollution, overfishing, climate change. Goal 14 aims to conserve oceans by reducing pollution, protecting ecosystems, addressing acidification, regulating fishing. The objectives are to prevent marine pollution, sustainably manage coastal areas, minimize acidification impacts, effectively regulate fishing. Targets include increasing protections, benefits for small island states, subsidies reform, international law enforcement, sustainable fishing. Research shows main pollutants are microplastics, sewage, plastic bottles/bags, fishing waste. Local and international cooperation is needed to sustainably manage oceans.
