🌊 73% of the world's 16,491 Marine Protected Areas (MPAs) are contaminated by sewage-derived wastewater, with tropical regions like coral reef zones being significantly worse (87-92% affected).

💧 Wastewater introduces a mix of pollutants that cause eutrophication, harm coral reefs and seagrass, and have been linked to coral disease and neurological issues in marine life, with significant human health and economic impacts.

⚖️ While MPAs are valuable, the study emphasizes that area-based protection alone is insufficient without addressing water quality. The global "30 by 30" target for ocean protection by 2030 is at risk if pollution isn't tackled.

💡 Solutions like advanced wastewater treatment plants, Membrane Bioreactor (MBR) systems, constructed wetlands, wastewater reuse legislation, and IoT monitoring are available and being deployed to combat this issue.
