Fishers fear it will completely block the remaining freshwater flow and further increase salinity levels, harming fish breeding and survival.  \n• Pollution Concerns: The article mentions existing industrial pollution in the Narmada and Gulf of Khambhat, highlighting the overall environmental stress on the region.  \nArticle summary  \n• [https://www.downtoearth.org.in/news/environment/fourth](https://www.downtoearth.org.in/news/environment/fourth)global-mass-coral-bleaching-great-barrier-reef-severely-affectedcorals-seen-dying-94913  \nArticle Summary  \n• The article discusses a significant coral bleaching event at the Great Barrier Reef (GBR), confirmed by Australian authorities. The event, which is feared to be the fourth global mass coral bleaching, has affected a vast area of the reef, larger than Italy. Aerial surveys conducted over two-thirds of the GBR Marine Park revealed that over 300 inshore, midshelf, and offshore reefs are experiencing bleaching, with some corals dying.  \n• Climate change is identified as the primary threat to the GBR and other coral reef ecosystems worldwide. The GBR, stretching over 2, 300 km and comprising around 3, 000 individual reefs, is experiencing bleaching events due to high sea surface temperatures exacerbated by climate change and El Niño conditions. The article emphasizes the urgent need for addressing climate change to protect these vital ecosystems  \nThe high seas are areas beyond 200 nautical miles from the exclusive economic zones of coastal countries.  \n[https://www.downtoearth.org.in/news/environment/countries-hope-to-bring-bbnj-or-high-seas-treaty-into-force-by-](https://www.downtoearth.org.in/news/environment/countries-hope-to-bring-bbnj-or-high-seas-treaty-into-force-by-)[ ](https://www.downtoearth.org.in/news/environment/countries-hope-to-bring-bbnj-or-high-seas-treaty-into-force-by-)[2025-only-2-have-ratified-it-so-far-94909](2025-only-2-have-ratified-it-so-far-94909) .  \nArticle summary  \nThe article discusses the challenges and goals surrounding the recently adopted international treaty focused on protecting biodiversity in the high seas (areas beyond national jurisdiction) . Here's a summary:  \n• Treaty in Focus: The BBNJ (Biodiversity Beyond National Jurisdiction) Treaty, agreed upon in March 2023, aims to establish regulations for the conservation and sustainable use of marine life in international waters. The treaty aims to increase the percentage of protected areas on the high seas. Despite covering more than two-thirds of the global ocean, only 1 .44 per cent of the high seas are protected.  \n• Challenges of Ratification: As of March 2024, only two countries have ratified the treaty. This is a critical step for the treaty to become legally binding.  \n• India's Role: While India hasn't ratified the treaty yet, it expressed support for its implementation at the Blue Leaders High-Level Event on Biodiversity Beyond National Jurisdiction.  \n• Concerns and Importance: The article highlights the urgency of pr","cbCaimrNIz1wPiOQ","https://ap.wps.com/l/cbCaimrNIz1wPiOQ","pdf",3833123,35,"English","# Marine and Gulf Ecosystems\n## Seasonal anoxia in the Gulf\n## Bhadbhut barrage and impacts on fisherfolk\n# Coral Reef Stress\n## Great Barrier Reef mass coral bleaching\n## Climate change and El Niño drivers\n# High Seas Governance\n## BBNJ treaty goals and ratification challenges\n# Hydropower Storage (Concept Note)\n## How pumped storage projects work","[{\"question\":\"What environmental issue is described for Gulf waters during summer months?\",\"answer\":\"Seasonal oxygen depletion (anoxia) turns deeper Gulf regions into a marine desert.\"},{\"question\":\"How does the Bhadbhut barrage relate to the problems faced by fishers?\",\"answer\":\"It is expected to worsen conditions after reduced freshwater flow from the Sardar Sarovar Dam, increasing salinity and harming fish breeding and survival, threatening fisher livelihoods.\"},{\"question\":\"What is the BBNJ treaty intended to achieve and what is the main legal challenge mentioned?\",\"answer\":\"The BBNJ treaty aims to regulate conservation and sustainable use of marine life in the high seas and expand protected areas.
