An 11-Billion Pound Plastic Gorilla is in Our Ocean

Posted On February 12, 2015 by

Walk along a beach or waterway and you’re apt to see a food wrapper floating on the water or glimpse a beverage bottle made of plastic hovering near the shore. Read an article about the ocean gyres, the so-called “garbage patches,” and you’re likely to hear about the vast amounts of plastics that are polluting the seas.

Three years ago, researchers at the National Center for Ecological Analysis and Synthesis (NCEAS) set out to quantify – for the first time – the amount of plastic waste entering the ocean from land-based sources.  Their research shows staggering results – with annual plastics inputs into the ocean exceeding 4.8 million tonnes and possibly as high as 12.7 million tonnes (approx. 11-26 billion pounds). Because the quantities are growing rapidly due to increases both in population and in plastics use, there may be as much as 250 million tons (550 billion pounds) of plastic in the ocean within another decade.  These findings were published today in the February issue of Science and provide more in-depth information about what is happening with plastics in the ocean.

Once plastics enter the marine environment they disperse across our global ocean. There is no one single entry point for ocean plastic pollution. In fact, the global problem is comprised of a myriad of local inputs from beaches and waterways around the world. But the recent research shows that the largest amounts of plastic in the ocean come from a relatively small number of rapidly developing economies. In fact, 83 percent of the plastic waste that is available to enter the ocean comes from just 20 countries; chief among them are China, Indonesia, and the Philippines with the United States rounding out the top 20. The economies where plastic inputs are greatest are those where population growth and plastics consumption is severely outpacing waste management capacity. In many of these geographies waste collection is simply nonexistent.

Interview: Building an Ocean Cleanup Brigade in Bangladesh

Posted On February 11, 2015 by

Ocean trash.  Marine debris. You’ve heard it’s a problem. An ever-increasing amount of plastic pollution is entering our ocean every day. Surprisingly, many countries around the world lack the most basic trash collection services. As incomes rise, people are able to afford more and more plastic goods. But in many countries, the ability to collect and manage waste isn’t growing at nearly the same rate. As a result more plastic is ending up on beaches, in rivers and eventually the ocean.

We’re lucky at Ocean Conservancy to have an incredible network of passionate and devoted coordinators and volunteers through our International Coastal Cleanup who work tirelessly to keep their local beaches and waterways free of harmful plastic debris. Just last week, I had the honor of interviewing our Bangladesh Country Coordinator, Muntasir Mamun, about the problems with marine debris and how the Cleanups in his country have been successfully recruiting more and more volunteers.

OC: Why are you so invested in our ocean’s health?

Muntasir: Bangladesh is the biggest delta on Earth and has one of the largest natural sandy sea beaches. Due to over population, Bangladesh is heavily threatened by the impact of trash. Moreover, thousands of rivers are going across my country and ending up being at the ocean. So, the trash being in the rivers (intentionally or unintentionally) are going to be in the ocean. Not only that, geographically Bangladesh is one of the most vulnerable countries from the impact of climate change.

Momentum Builds for Ocean Change

Posted On February 10, 2015 by

There’s been a recent spate of good news about people dealing with the global problem of ocean acidification at the local level.  Over the past month, the Maryland Ocean Acidification Task Force and Maine Ocean Acidification Commission have reported on what ocean acidification means for their states, and what each state can do to protect its local ocean.  These are the first comprehensive state reports on the east coast to put forth suggested actions addressing acidification.

Both commissions included scientists, fishermen, shellfish farmers, state agencies, elected representatives and community groups who are especially concerned about their shellfish farms and wild fisheries, especially blue crabs and American lobsters. I attended the Maryland Task Force meetings too.

During the meetings over the summer, we heard of shellfish farmers in Maryland seeing lower baby oyster production levels.  Even though the cause has remained a mystery, no one could rule out ocean acidification. This lower amount of oyster seed still remains unexplained, but everyone agreed that the marine resources and coastal communities of the state are too important to be left in such uncertain conditions.  In fact, the Maryland report includes recommendations for increasing ocean acidification research and monitoring so the state can understand just what is happening.

BP Trial Highlights Lasting Offshore Impacts in the Gulf

Posted On February 2, 2015 by

Last week during the ongoing BP trial in New Orleans, the testimony of Donald Boesch, a professor of marine science at the University of Maryland, was a real call-to-arms for ocean-lovers. Much of the impact to marine fish, habitats and wildlife has been “out of sight, out of mind” and in many cases off limits to the public.

Through Boesch’s testimony, the U.S. prosecutors hope to highlight the seriousness of the BP Deepwater Horizon oil disaster—one of eight factors that will determine the level of environmental fines the judge will set—and make the case for fines as high as $13.7 billion. Boesch painted an alarming picture of potential marine impacts, with deep-water corals and other living creatures on the seabed of the Gulf covered in oil.

Breaking Arctic News

Posted On January 28, 2015 by

Yesterday, President Obama issued permanent protections from future oil and gas drilling for some of the Arctic Ocean’s most significant marine areas. The President’s action is an important and positive step to limit risky drilling, and will help protect the Chukchi and Beaufort seas, including vital walrus habitat at the Hanna Shoal.

At the same time, however, the Bureau of Ocean Energy Management (BOEM) issued a draft proposed program that calls for additional oil and gas lease sales in other areas of the Arctic, even though oil companies have not shown they are able to operate safely and responsibly in the Arctic. Extreme conditions like changing sea ice, fog, and high winds make meaningful cleanup all but impossible. A disaster like the Deepwater Horizon in the Arctic would devastate marine wildlife and jeopardize food security in Alaska Native communities.

Join us in sending a message to BOEM: No Arctic Ocean drilling.

Stand against reckless drilling in the Arctic Ocean. Tell BOEM not to sell Arctic oil and gas leases in the 2017-2022 program.

BP Back in Court

Posted On January 20, 2015 by

BP once again must appear in court today as the final phase of the BP trial begins in New Orleans. This is the third phase of a multiyear trial to determine how much BP and other responsible parties should pay for their role in the BP Deepwater Horizon oil disaster in the Gulf of Mexico. Just last Thursday, the Judge issued another ruling, finding that 3.19 million barrels of oil were released into the Gulf. This means that the maximum fine BP will face is $13.7 billion. This final phase of the trial will focus on eight factors, as required by the Clean Water Act, including BP’s history of prior violations and the seriousness of this violation.

A key factor in court will be BP’s efforts to minimize the harm. In other words, did BP do enough in responding to the disaster to justify lowering their fine? Yes, BP took efforts to stop the flow from the well and the spread of oil, but BP also lied about the rate at which oil was spewing from the well.

The economic impact of the penalty on BP will be interesting to watch as well. The court will need to determine whether this inquiry focuses on BP (the parent company) as a whole or only on its subsidiary, BP Exploration & Production, known as BPXP. BP is expected to argue that the recent dip in oil prices should be factored into this inquiry. (This assertion, as you might expect, has been met with criticism.)

Tasting Ocean Acidification

Pink shrimp raised in tanks that simulate the more acidic ocean expected in the future just don’t taste right, according to a recently published research paper from Sweden.  For the first time, a scientific study has looked at the effects of future ocean conditions on the taste of seafood.

Teaming up with a professional chef, the researchers cooked and served local shrimp that had been raised for three weeks in high carbon dioxide conditions alongside shrimp raised in regular conditions. Volunteer taste testers then tried both kinds of shrimp and scored them on appearance, texture, and taste.

Ocean acidification didn’t affect texture at all, but it significantly hurt the shrimps’ appearance and taste scores.  Shrimp raised under regular conditions were more than three times as likely to be rated the best shrimp on the plate, and the shrimp raised with high carbon dioxide levels were about three times as likely to be rated the worst on the plate.
