Giant Ocean-Trash Vortex Attracts Explorers

Scripps' Jim Dufour is advising Project Kaisei and its efforts to quantify the amount and condition of trash in the little-studied region.

"We need to do the chemistry and see how much plastic is reaching the water and the ocean sediments, how much is being broken into [these] tiny particles and ingested by marine life at rates we can't imagine," Dufour said.

The project will also explore clean up options, which aren't as easy as simply scooping up waste.

"It's a tough job. [Open-ocean] fish live under things like Styrofoam cups. If you simply drag a net you'll end up killing off a lot of the resources that you want to protect," Dufour said.

Close to Home

Kaisei's Woodring stressed that preventing more plastics from reaching the ocean has far less to do with illegal ocean dumping than choices made closer to home.

Eighty percent of the waste stream is land-based, explained Woodring, also a Hong Kong-based environment-and-technology entrepreneur.

"It's coming from rivers, streams, drains, gutters, and beaches within a mile or so of the shoreline."

In many parts of the world, particularly in developing nations, people have no means of disposing of the plastic bottles and packaging that have become ubiquitous parts of daily life.

Project Kaisei hopes to somehow assign value to that plastic, particularly the overwhelming majority that is never recycled.

Technologies that convert plastic to fuel, clothing, or simply more profitable plastic could give people a good reason to pick up all that plastic and make a profit from it.

"It's controllable," Woodring said. "We have to let people know that enough is enough, but it's not just a negative story about toxicity and wrecking our oceans. There is a huge amount of opportunity for innovation."

Plastiki

Innovation is a hallmark of David de Rothschild's expedition.

The environmentalist and Adventure Ecology founder will sail a boat made of recycled plastic—mainly discarded water bottles—from San Francisco to the garbage patch and beyond to Sydney, Australia, in coming months.

His craft, dubbed the Plastiki, is a nod to famed explorer Thor Heyerdahl, who led a 1947 voyage on the Kon-Tiki to test theories of Polynesian settlement by South Americans.

De Rothschild's voyage hopes to show people what can be accomplished by rethinking current uses of plastic.

"Plastic is not the enemy," said de Rothschild, also a National Geographic Emerging Explorer. (National Geographic News is owned by the National Geographic Society.)

"But it's our understanding of disposal and reuse that's to blame."

De Rothschild explained that Plastiki's construction has already jump-started research into a future "smart plastics" industry—before ever leaving port.

For instance, studies are underway on glues that could someday replace common marine epoxies and plastics that could replace non-recyclable fiberglass.

"The Plastiki [voyage] will be a great adventure, but I think more exciting is the ability to create a conversation on the issue of smarter plastics."
