New ocean uses may create new concerns. Now we have to worry about deep sea mining.
What are the impacts of dredging the deep sea for minerals? I don't know, but I doubt anyone else knows either. Given the lack of care exercised in the early days of ocean fishing, I'm not confident that deep sea mining will be carefully managed.
But I suppose I really shouldn't worry since concerns about impacts are already being dismissed as "knee-jerk environmentalism" by a geologist promoting deep sea mining. Yeah, and Silent Spring is still being attacked by some.
Let's hope that cool heads prevail and that ocean mining gets a thorough review before widespread dredging begins. Go to digistar and see for yourself their view of the future of ocean mining.
