Sharks risk losing their bite as oceans turn acidic: Study

Sharks continually shed and regrow teeth throughout their lives, replacing worn or lost teeth with new ones. That makes them particularly good at catching prey. However, these top marine predators could lose their literal edge as ocean acidification damages their teeth and makes it harder to keep and replace them, a new study says. “Shark […]

US court gives Māui dolphin charity hope in fight over seafood ban

Māui dolphins are a headache for Fisheries Minister Shane Jones, not least because he doesn't believe they exist.

There is ample and growing evidence of the harm #bottomTrawling causes in the ocean. Primarily to biodiversity but also to the oceans capacity to regulate climate. It is absolutely indefensible to continue this destructive, reckless practice in the middle of an ecological crisis. 🌊

“the ocean is already changing, and projected shifts in North Atlantic convection are a real concern. Even if a collapse is unlikely, a major weakening is expected, and that alone could have serious impacts on Europe’s climate in the decades to come. But the future of the Atlantic circulation is still in our hands.”
