40,000 Seagrass Plants for the Baltic
Sea Shepherd Germany’s crew and over 120 volunteers planted 40,000 seagrass shoots across 5,000 m² of the Baltic Sea. These underwater meadows are “ecosystem engineers”: they absorb carbon, protect coastlines, and serve as nurseries for countless species. Monitoring dives show the plants are thriving, with growth far beyond expectations. Every blade planted helps bring new life and resilience back to the Baltic.

Philippines Safeguards a Coral Treasure
Panaon Island, home to some of the world’s healthiest coral reefs, is now a legally protected seascape covering 61,204 hectares. The area shelters endangered whale sharks, sea turtles, and vital fish nurseries while supporting local communities. The new law sets ship speed limits, strict zoning, and community-led management to keep the reefs thriving. It’s a milestone for the Philippines’ 30x30 conservation goals — and a win for both people and marine life.

French Cities Take Tuna off School Menus
Eight cities — including Paris, Lyon, Grenoble, and Montpellier — have removed tuna from school canteens after NGOs exposed unsafe mercury levels. Current EU rules allow tuna to contain far higher mercury than other fish, posing risks for children. Until limits are lowered, these municipalities are protecting students’ health while calling for stronger national and EU safeguards. It’s a bold step showing how local action can drive systemic change.

Scotland Expands Seabed Protection
Scotland has banned bottom trawling across nearly 60,000 km² of offshore seabed, including five Marine Protected Areas now fully shielded from this destructive practice. Fragile ecosystems like burrowed mud habitats and cold-water reefs will benefit, supporting biodiversity and healthier seas. Conservationists celebrate this as a milestone, while reminding us that inshore waters remain vulnerable. It’s a strong signal that large-scale protection is possible — and must keep growing.

Microbes Show Ocean’s Hidden Resilience
Scientists discovered that marine microbes swap about 250 genes per liter of seawater every day — a powerful process that helps ecosystems adapt to change. These tiny organisms recycle nutrients, clean water, and give the ocean resilience against warming and pollution. The findings also challenge how we define species, showing just how dynamic ocean life really is. Even the smallest forms of life are playing a big role in keeping the ocean alive.
