Every 60 seconds, what amounts to roughly a garbage truck full of plastic makes its way into the ocean. That means that over the next year about 8 million tons of plastic will enter the ocean, creating a massive amount of marine pollution.
It’s estimated that if we don’t do anything to address this source of pollution, there will be one pound of plastic for every three pounds of fish in the ocean by 2025.
Preventing further damage to our oceans will require a coordinated global effort, and the United States has a vital role to play in leading this charge.
True confessions: I’m secretly a total Harry Potter nerd. Okay, maybe it’s not so secret… (#TeamHufflepuff anyone?) Which is why I did a literal happy dance in my living room when I saw Emma Watson’s gown for last night’s Met Gala.
The following is a guest blog from Dr. Chelsea Rochman, who is currently serving as a Smith Postdoctoral Fellow in Conservation Biology.
For decades, we have heard concerns regarding the entanglement of marine mammals and sea turtles in marine debris. We see images of seabirds, turtles and whales washing up with bellies full of trash. And more recently, we see constant media attention on microplastics—small pieces of plastic debris less than five millimeters in size. Marine debris is everywhere. It is reported from the poles to the equator and from the surface to the seafloor. It has been recorded in tens of thousands of individual animals encompassing nearly 600 species.
With such vast and abundant contamination, comes a perception that marine debris is a large threat to the ecology of our ocean. As part of a working group at the National Center for Ecological Analysis and Synthesis (NCEAS) facilitated by Ocean Conservancy and focused on marine debris, I worked with a group of scientists to ask if the weight of evidence demonstrating impacts matched the weight of this concern? The findings of our analysis have just been published.
It’s getting really bad. Practically every kind of animal, from plankton to whales, is now contaminated by plastic. It’s in the birds, in the turtles, in the fish. At the current rate, we could have 1 ton of plastics for every 3 tons of fish by 2025.
This is nobody’s plan. It’s not the plan of the plastics industry, it’s not the plan of the consumer goods industry and it’s certainly not the plan for those of us who love and need the ocean. Nobody wants this.

If you have been reading my recent posts, you have noticed that I have been discussing the emerging science on plastic pollution in the ocean and exploring what we need to do to stem the tide. It started in February, when a groundbreaking study showed that 8 million tons (nearly 17 billion pounds) of plastic flows into the ocean each year, mostly from a small number of Asian nations where local waste management can’t keep up with rapidly growing plastic use. Then scientists estimated that nearly all the worlds’ seabirds will be contaminated by plastics by 2050 unless conditions don’t change. And a study published only days later showed that half the globe’s sea turtles are likely to suffer the same fate. Today, we need to think carefully about the latest study, showing that plastics can be found in many of the fish that we eat. We don’t yet know if eating plastic-laden fish negatively impacts our health, but today’s study is another brick in the growing wall of scientific evidence that demonstrates that plastics are a major threat to the global ocean and ultimately, ourselves.

I got a kick out of Groundhog Day, the comedy starring Bill Murray and Andie MacDowell that was released in 1993. With Murray waking each day to relive Groundhog Day alongside Punxsutawney Phil and his co-anchor, the movie was lighthearted and fun. But the science of ocean plastic pollution is starting to feel a lot like Groundhog Day. And the storyline is becoming much more troubling with each new publication.
This week a new study in the peer-reviewed journal Global Change Biology calculates that over half of the world’s sea turtles have ingested plastic; this follows on the heels of a publication last month by some of the same scientists that predicted that nearly all of the world’s seabirds would be contaminated with plastics by 2050 unless action is taken soon. With each new publication, the case for a global strategy to stem the tide of plastics into the world’s oceans becomes ever more vital.
You have likely seen the pictures of albatross chicks chocking on plastics. These images are tough to look at and the death these birds suffer from ingesting plastics is gruesome and painful. Albatross consume a whole range of plastics that float in the ocean, from cigarette lighters, to toothbrushes to shards of plastics from a huge variety of other plastic products. As a conservation organization, Ocean Conservancy is deeply troubled by the impact of plastics on these magnificent birds. But how pervasive is this problem, really? A new paper in the peer-reviewed journal PNAS gives us a disturbing answer. It turns out plastics in seabirds is a very big deal. It is global, pervasive and increasing. And it has to be stopped.
