About George Leonard

George Leonard is Director of Strategic Initiatives at Ocean Conservancy. A long-time scuba diver, George knew he wanted to be a marine biologist at the age of 12 when he first watched Jacques Cousteau's TV special on the sleeping sharks of Yucatan in 1975. During his graduate work, he logged over 400 dives in 3 years, studying California's kelp forests, the undersea equivalent of a tropical rain forest.

Ocean Acidification: A Pain in the Arctic

Posted On May 17, 2013 by

No matter where you live, if you go outside and start walking north, at some point you’ll reach the Arctic Ocean. A vast expanse at the northern reaches of the planet, the Arctic Ocean supports a dizzying array of ocean wildldife, including the charismatic – and much threatened – polar bear. Most readers of The Blog Aquatic know that summer sea ice has been rapidly melting, caused by human-induced climate change from our ever rising global carbon emissions. Indeed, the concentration of carbon dioxide in the global atmosphere just broke a new record high.

But more poorly understood is that carbon dioxide is beginning to undermine the Arctic ocean itself through a process called ocean acidification. No less than 10 key scientific findings  can be found in a just-released assessment of ocean acidification undertaken by an international group of independent scientists.

The People have Spoken: Massive Pushback to Genetically-Engineered Salmon

Posted On April 26, 2013 by

Two and half years ago, genetically engineered salmon exploded on the national stage.  April marked another big milestone in the ensuing debate about whether genetically engineered animals will be allowed in the U.S. food supply.  This isn’t some esoteric, pointy-headed debate.  It really is about the future of food and what you feed your family. And as an ocean conservation organization, we are especially concerned about the consequences for the future of seafood, wild fish and healthy oceans.

The Food and Drug Administration’s final comment period has now closed on the agency’s draft decision to approve an engineered variant of farmed Atlantic salmon.  We hope you let your voice heard by submitting comments to the agency.

When Facing Ocean Acidification it’s Location, Location, Location

Posted On March 7, 2013 by

For us landlubbers, it is obvious that place matters.  My home town in central California is a pretty different place than say, Washington DC, where I often travel to advocate on behalf of ocean conservation.  The weather is different, the food is different, and the culture – not to mention the politics – is certainly different.

It turns out that place really matters in the ocean too, especially as it relates to ocean acidification.  Never heard of ocean acidification?  Check out some of my earlier posts to learn more about the basics.  But what we learned from scientists last week is that the chemical characteristics of the ocean vary greatly from place to place, and as a result some areas may be especially sensitive to increases in carbon dioxide and other drivers of acidification.  A team of oceanographers led by Dr. Aleck Wang sampled seawater from Texas to New Hampshire and measured the total amount of carbon in the water as well as what scientists call “alkalinity.” The ratio of alkalinity to total carbon is a measure of the buffering capacity of the ocean, or in layman’s terms, the ocean’s ability to resist acidification. What the scientists found was that the Gulf of Maine is much more susceptible to acidification than the Gulf of Mexico or the southeastern coast.  Continue reading »

Mark Lynas and GMOs: the Case of Genetically Engineered Salmon

Posted On January 16, 2013 by

When I was rambunctious kid, my mother always told me it was more effective to get someone’s attention with a whisper than a shout. Earlier this month, Mark Lynas, the well-known anti-GMO activist, got everyone’s attention by changing his long-held position on genetically-modified foods. But he didn’t scream it from the rooftops or otherwise perform a media-grabbing stunt like his famous pie-throwing incident. He calmly, thoughtfully, and yet forcefully explained in front of an academic audience in London how he had come to this change of heart.

In short, Lynas maintained he “had discovered science”. Over the course of an hour, he minced no words while eviscerating what he called the anti-science NGO community that has long opposed the development and deployment of GE crops – and of which Lynas was a leading figure for over a decade. The foundation of his argument was that there is now a scientific consensus that there are no health effects of genetically-engineered crops and after 3 trillion meals eaten with no demonstrable evidence of harm, “the GMO debate is over”. While many have countered Lynas’ treatise, there remain a host of unanswered questions about the environmental risks of GE animals – especially fish – should this technology proliferate beyond plants. Scientific consensus has not yet emerged and it is needed if a skeptical public is to accept GE fish.

The Seafood Seven? Senators Act to Delay FDA Ruling on GE Salmon

Posted On January 12, 2013 by

If you missed the Food and Drug Administration’s controversial ruling during the holidays – to recommend approval of an engineered variant of farmed Atlantic salmon as the first-ever, genetically engineered animal allowed for human consumption – you aren’t the only one.

It came as a surprise to conservationists, media and policymakers alike, and the ruling opened a surprisingly short public comment period that closes on February 25.

Thankfully, seven U.S. senators are standing up for the ocean and for healthy, sustainable seafood by sending a letter to FDA commissioner Dr. Margaret Hamburg today requesting a 60-day extension to the public comment period. The senators rightly believe that the public deserves more time to adequately review and comment on the FDA’s lengthy, yet intentionally narrow, report that will have far-reaching implications for the future of fish and the health of the seafood on our plates and in our ocean.

Ocean Conservancy commends the strong stance taken by Senators Begich and Murkowski of Alaska, Senators Murray and Cantwell of Washington State, Senators Wyden and Merkley of Oregon, and Senator Barbara Mikulski of Maryland.

FDA Misses the Boat in Signaling Approval of Genetically Engineered Salmon

Posted On December 28, 2012 by

Just as I was getting ready to head out for my Christmas break last week, my email Inbox signals that the Federal Food and Drug Administration (FDA) has released its recommendation to approve the first-ever, genetically engineered animal for human consumption. For those who track the FDA, they know this isn’t unusual – the agency often makes controversial rulings right before the holidays, when decision makers, media and the public are trying to have some well-deserved downtime with their families. It was a kind of an unwelcome, fishy Christmas surprise, nestled among the garland and mistletoe.

My latest piece for National Geographic explains just how dangerous this recommendation is and what Congress needs to do in the new year to make sure these controversial fish do not make it to the ocean. The U.S. is simply not equipped to deal with this scenario.

Dr. Lubchenco’s Return to Academia: A Personal Perspective

Posted On December 14, 2012 by

When Dr. Jane Lubchenco, Administrator of the National Oceanic and Atmospheric Administration (NOAA) announced this week that she was returning to Oregon State University for personal reasons, I wasn’t surprised. I had the pleasure of being a postdoctoral associate in her lab for a short while in the late 1990’s and I came to know how important her home on the Oregon coast was to her.

Over the last 4 decades, Dr. Lubchenco has built a remarkable scientific career which has ranged from intertidal ecology to serving as President for the American Association for the Advancement of Sciences (AAAS). As a recent Ph.D. in her lab, I benefited greatly from her scientific advice. But perhaps more importantly, as a father of two young children at the time, I benefited from her guidance on how to balance work and family.
