Words of lost hope and unsolvable problems have been circulating the past few days in response to an article highlighting Ivan Macfadyen’s sail from Melbourne to Osaka. In the article, this long-time sailor describes the waters of his Pacific crossing as desolate and without life, “… for 3,000 nautical miles there was nothing alive to be seen.” Macfadyen goes on to describe in detail that in place of the missing life were abhorrent sights and volumes of garbage.

Reactions on social media have included words such as sad, scary and heartbreaking. But most of all, I’m concerned about posts like this one:

Tweet from Coast Road: I'm outta ideas. What do we do now?

It is clear that our ocean is facing unprecedented times and growing environmental challenges. In many places, we’re treating rivers and coastal waters like refuse pits for our unwanted waste. We are catching too many fish, and we are putting too much carbon dioxide into the atmosphere, where it is finding its way into the ocean with troubling consequences. However, I’m not yet ready to throw in the towel, and it troubles me that this article leaves people feeling hopeless. We know that if people are left with despair, they have little motivation to work toward solutions.

While I cannot discount or confirm Mr. Macfadyen’s accounts of his journey, we should be careful in our interpretation of his personal story. While it is a powerful observation, it is only a single observation. Science—the thorough, replicated and verified collection of ocean observations—must be the foundation upon which we understand a changing ocean and from which we advocate and empower society to strive for solutions.

As a marine scientist at Ocean Conservancy, I have been to the North Pacific Gyre, Gulf of Alaska, Caribbean Sea and Sea of Japan researching and cleaning up ocean trash. In all my travels, never have I seen debris conditions so voluminous or severe, nor have I heard of such atrocities from my scientific colleagues. Don’t get me wrong—there is stuff out there—a lot of it. But the bulk of that material is comprised of small, fragmented plastics that lie just below the water’s surface, posing a range of ingestion threats to turtles, birds and fishes. To more fully understand the impact of plastics on ocean health, Ocean Conservancy has brought together the world’s top scientists to quantify the extent and impact of the global marine debris problem. This global synthesis should provide new insights into this global problem.

Mr. Macfadyen also incorrectly states that there are no organizations trying to solve the problem of marine debris. In fact, a large number of concerned people, engaged governments, independent scientists and passionate nonprofit organizations are working diligently to address these complex issues. Ocean Conservancy is joined by a community of hard-working and passionate conservation organizations such as Surfrider, 5Gyres Institute, Algalita Marine Research Institute, NRDC and Plastic Pollution Coalition that are deeply committed to the fight to stop plastics and trash from reaching our beaches and waterways.

I am not downplaying the struggles our ocean faces. Plastic pollution, ocean acidification and commercial overfishing are serious problems that must—and are—being addressed. But if we want to truly confront these issues, we must be principled and scientifically grounded in our strategy. And if we want people to join the fight and feel like their efforts are worth something, we must empower them with ideas and hope, not fear.

We need a “Mythbusters” for Marine Debris Fri, 04 May 2012 17:46:17 +0000 Nick Mallos

Plastic doesn't just disappear; it breaks down into smaller and smaller pieces. Scientists are just starting to understand the impacts fragmented plastics have on our ocean. Photo credit: NOAA

A “gigantic floating island of trash.” The media has been full of stories about an ocean drowning in plastic for years. It’s great that public awareness about ocean trash has skyrocketed, but awareness built on fundamental misconceptions won’t lead to durable, long term solutions—particularly with respect to plastics. What we need now is rigorous scientific analysis of both the scope of the problem and the best ways to solve it.

I’ve been to—and sailed through—the North Pacific Gyre and the reality is that there is no huge, floating island of trash twice the size of Texas – instead, large areas of the Pacific are a sort of trash soup containing lots of small bits of plastic. And I mean LOTS. Of course to most, the size or viscosity of the trash in the ocean misses the point. Trash shouldn’t be in the ocean; it’s a problem we can and should collectively solve.

But as a scientist, I know that compared to other areas of ocean research, the science of marine debris is still in its infancy and evolving quickly. There is a lot we still don’t know but some new research is troubling. Just last month, researchers published findings that show that plastics may not be just at the surface, but may be widely distributed in deeper waters. While we do not know exactly how much plastic is in our oceans, these findings indicate plastics may be more widespread than previously thought. Because global data on marine debris are fragmented, scientific synthesis is needed and predictive models will be necessary to fully quantify how much plastic is in the ocean, where it is, and what its impacts on marine ecosystems are.

At Ocean Conservancy, we want science to drive the debate. That is why we are supporting a scientific working group at the National Center for Ecological Analysis and Synthesis to improve the state of the science of ocean trash. This work is just getting underway but is sure to help inform what we can all do about trash in our oceans.
