🗞️ Driving the news: A team from The Nature Conservancy (TNC) is leading a project to restore oyster reefs in Hong Kong
This initiative addresses the vital role of these reefs in supporting marine biodiversity and coastal resilience

🔭 The context: Oyster populations globally have significantly declined due to overharvesting, habitat destruction, and pollution, making them the most endangered marine habitat 
In Hong Kong, a century of urbanization and industrial activities has severely impacted oyster reefs.

🌍 Why it matters for the planet: Oysters play a crucial role in marine ecosystems as filter feeders, improving water quality
A single oyster can filter up to 200 liters of water per day, demonstrating their importance in maintaining healthy marine environments

⏭️ What's next: Efforts by TNC and the University of Hong Kong focus on research and conservation, emphasizing the need for standards and long-term monitoring in restoration projects

💬 One quote: “You can’t just call anything restoration. Restoration needs standards and long-term monitoring." (a spokesperson from The Nature Conservancy)

📈 One stat: 85% of global oyster reefs have already been wiped out, highlighting the urgency of restoration efforts.
