At Sea with 5 Gyres - Cuppow Co-Founder Joshua Resnikoff
Our own Joshua Resnikoff spent the first week of June joining the 5 Gyres Institute on their 2015 S.E.A. Change Expedition to the North Atlantic Sub-tropical gyre. The purpose of this mission was part of a larger ongoing effort to assess the overall global abundance of floating surface microplastic debris.
The collection of this debris has been termed “plastic smog” by 5 Gyres founders Marcus Eriksen and Anna Cummins, and its is not currently wholly understood. Through sea surface trawling and team-based spotting, the 5 Gyres crew is able to develop large datasets that aid in evaluating the true scope of the problem. This work has directly led to the first-ever state microbead legislation, caused 16 major cosmetic companies to remove microbeads from their products, and is the basis for a co-sponsored national bill being debated right now!
Based on the findings of Eriksen, Cummins, and many other field researchers, models suggest that 250,000 tons – some 5.25 TRILLION pieces - of microplastic are currently afloat in our oceans.
Large microplastic pieces have also been demonstrated to act as chemical sponges, adsorbing chemicals from the ocean that result in concentrations of up to 1 million times more than the water around them. As fate would have it, they share a size class with mesozooplankton, one of the cornerstones of the maritime food chain. In some parts of the world, such as the Sargasso Sea in the North Atlantic, large microplastic exist in 40-fold higher concentration than the plankton. Local feeding fish are unable to tell the difference between the two; they eat the plastic, bigger fish eat the feeding fish, and humans eat the big fish. As we pollute our oceans, we are quite literally poisoning ourselves.
Unique to this problem is that it is singularly human-caused – there can be no debate or off-set for naturally occurring phenomena. The creation of single-use disposable goods from a super-durable material is counterintuitive. This is the demonstrably shortsighted result of poor product design, poor waste management systems, and a lack of human accountability. We are only 50 years into our experimentation with plastic as a resource, and its potential negative effects are now irrefutable.
Despite this, when used responsibly, plastic empowers humankind with better medicine, efficiency in materials and goods transportation, and even the ability to travel into space. Therefore we cannot define ourselves as anti-plastic, but must take the stance of anti-pollution. We must end our dependence on single-use disposable plastics and do better to utilize the positive aspects of this reusable, durable material.
