The online ocean science community has been vocally skeptical about the Ocean Cleanup, a device that aims to physically remove plastic pollution from the ocean. Drs. Kim Martini and Miriam Goldstein published a technical review of its feasibility over at Deep Sea News, and Andrew asked some important questions that have yet to be answered. Also, be sure to read environmental journalist Chris Clarke’s thorough overview of these concerns.
Overall concerns include a lack of understanding of the problem (including but not limited to the fact that much of the harmful ocean plastic is small and well-dispersed), insufficient structural integrity for a large object that will be deployed in the open ocean (which would result in the object breaking and creating even more ocean garbage), and the fact that this device is designed to aggregate objects of a certain size to remove them from the water but cannot distinguish between plastic and living things.
Mainstream media coverage has been noticeably less critical of the Ocean Cleanup, often presenting the idea as revolutionary and it’s creator as a genius.

I am not an expert in ocean plastic pollution. However, the uncritical tone of most mainstream media coverage of the Ocean Cleanup does not seem to correspond with my impression of expert opinion on this matter from speaking with expert colleagues who study this.
Through professional contacts, I developed a list of 51 ocean plastic pollution experts who work in academia, government, and the environmental non-profit sector, and I sent them some questions about the Ocean Cleanup. 15 (4 in academia, 5 each in government and the non-profit sector, and 1 in industry) agreed to participate in an anonymous survey. While this is not (and not intended to be) an exhaustive survey of the entire field of ocean plastic pollution, the broad agreement among a diverse group of experts is telling. Below, please see what they had to say through some representative quotes. Some respondents chose to provide an on-the-record quote, while many chose to remain anonymous out of concerns about reprisal.
I also asked Lonneke Holierhoek, COO of the Ocean Cleanup, to respond to these concerns. Her comments are included in each section.

Imagine, for a moment, that you’re in middle school. The spring formal is approaching and if you don’t have a date, you will literally die ohmygod. Your goal is “find someone to go to the dance with me”. You can’t just walk into the cafeteria and scream “SOMEONE GO TO THE DANCE WITH ME”. (I mean, you can, but…) You need to be tactical. You need to have a specific audience in mind.
A poorly defined audience (or one that is overly broad) is the root cause of the vast majority of issues I run into when I’m working with someone on their science outreach. From “I don’t know where to start” to “I can’t get anyone to listen/subscribe/come to my talk/donate,” my first question is always going to be “who is your audience?”. My next question is going to be “okay, now can you narrow that down”?.
The temptation is always going to be to have the broadest audience possible. If you aren’t appealing to EVERYONE you might miss out on potential opportunities! You could turn away a potential audience! You could miss out on the chance to be the most beloved science communicator that ever communicated!
How much of the ocean is really protected?
When the International Astronomical Union changed its definition of what constitutes a planet in our solar system in 2006, demoting hapless Pluto to a dwarf planet, the decision sparked fierce scientific debate and an outcry from the public. But after all was said and done, we earthlings now have a better understanding of our celestial neighborhood, with eight perfectly nice authentic planets, and a greater appreciation of what it takes to be in that exclusive club.
Now, the ocean science community may be facing its own “Pluto Moment.”
The International Union for Conservation of Nature (IUCN)—keeper of the Red List, the most comprehensive source on the conservation status of life on Earth—also sets the global standard for marine protected areas (MPAs). The IUCN has numerous subcategories of MPAs, from fully protected areas to those that allow some fishing or other activity, but in the group’s eyes all MPAs must be created with the primary goal of conserving biodiversity.
