Is deep sea mining bad for the environment? 🔊
The search for minerals is leading some corporations to begin mining the ocean floor, but scientists warn that this could devastate fragile ecosystems that will have repercussions that we still don’t understand. What is going on in the deep sea? What precautions...
Safeguarding our ocean ecosystems from tipping points
Interview with Professor Simon Thrush (head of the Institute of Marine Science, University of Auckland) Your research focuses on ecosystem tipping points. What are they? A tipping point is a sudden, abrupt, often dramatic change in the way that a natural...
Q+A: Why are shark populations in decline?
