Each commons must provide a healthy place for fish to live. The water must be free of pollutants and excess sediments, and in the face of global climate change, not too warm, or in the case of our oceans, too acidified. If this is what a healthy commons needs, how do we avoid the tragedy?
The price of oil has dropped to the point that old approaches and operations -- such as Arctic drilling and controversial pipelines -- make no sense and are obsolescent in the face to new competitive investment in alternatives.
The Pope has been especially clear and vocal about his views of climate change as a real, pervasive, and devastating factor in today's world and that our understanding and response to the problem is essential to the future survival of all people worldwide.
It's one thing to lament the continuing loss of the world's coral reefs due to rising ocean temperatures and acidity -- one study says they shrank from 240,000 square miles in 1997 to 108,000 in 2011 -- but it's quite another thing to put an actual price tag on that loss.
The world ocean is a sick sea. The symptoms are no longer deniable; the evidence mounts daily in nauseating waves of reported spills and leaks, dying reefs, depleted fisheries, and vast areas so oxygen-deprived that nothing lives. I keep looking for the good news.
Marine Protected Areas (MPAs) -- the national parks of the seas -- are being designated all over the globe. Which is fantastic news. Who doesn't want to give fish species verging on extinction a break?
COPENHAGEN -- Our climate models that predict how fast the glaciers are melting and the sea is rising don't take into account a lot of complex processes. Everything is happening faster than we thought it would.
How can we be largely unaware that such an important piece of the earth's ecological puzzle -- two-thirds the size of the continental U.S -- is disappearing?
For many reasons, water samples from different depths have to be collected and brought up to the surface for analysis in labs, and it can be difficult to preserve the integrity of these samples.
To go to Greenland was mind blowing, heartbreaking, painfully beautiful and terrifying, all at the same time.
When it comes to saving our oceans, I'm wondering: What would Pope Francis do? With his sprawling encyclical on the fate of our planet this month, the pope became an unexpected revolutionary. I never thought I'd see bold environmental leadership arise from this powerful, historically conservative institution.
Given the importance of seafood to our coastal communities, our economies, and as a major source of protein for people around the world, it is important that we conduct scientific research so we can better understand how various organisms will react to acidification in the coming years.
What would you do with $10 million to incentivize breakthrough technologies to save our oceans?
My primary job is to manage the teams, and when I first began working with them, I expected I'd have to breakup a headlock put on an engineer by a marine chemist.
The dying seas are an economic issue as well as a survival issue, and the corporate leaders of Legal Sea Foods and Taylor Shellfish of Washington will be speaking at the summit about preserving our fish stocks.
The finalist teams are global in scope, coming from four different countries (Japan, Norway, the United Kingdom and the United States).
